How to Find a Good Mechanic

Are you struggling to find a good mechanic? This blog tells you the important information you need to know on how to find a good mechanic that suits your Automotive needs.

Cars have become complex computerised, self learning  complicated electronic machinery. They take skill & expensive machinery to maintain & service.

First step is to get rid of the image of the greasy pot-bellied unshaven bogan in overalls with the filthy greasy rag hanging out of his pocket. That image should have been killed off in the nineties & yet its ironic how many times I speak to  people who have this concept & in turn do not become my customers.

The Automotice Doctors

Mechanics are the Automotive industry doctors.

Automotive Problems are complex & can be very expensive so they need a correct procedure & correct diagnostic techniques to isolate a problem.

It is so frustrating when customers want immediate solution & price over the phone for a complex problem without or for- going a correct diagnostic process.

Characteristics of a Good Mechanic

  • A good mechanic enjoys fixing problems.
  • A good mechanic uses a process to isolate the problem.
  • A good mechanic uses attained facts, logic & can back up his theory.
  • A good mechanic does not guess what is wrong!.
  • A good mechanic invests in the very best equipment.
  • A good mechanic uses the very best parts
  • A good mechanic continues to do the latest courses, study develop new techniques.
  • A good mechanic knows how to market his own business & refuses to use Marketing companies because he believes & is strong enough to market his own brand & his/her own business!
  • A good mechanic does not have to use cheap service specials, gimmicks ,shop a dockets or raffle bicycles in lieu of reviews.
  • A good mechanic has honest unfiltered google reviews.(even negative ones)
  • A good mechanic likes to explain so you can learn about your car.
  • A good mechanic loves his job.
  • A good mechanic has a huge tool cabinet of every tool you can imagine.
  • A good mechanic likes to teach.
  • A good mechanic has always got a project going on.
  • A good mechanic has a mission statement.
  • A good mechanic has a brand & logo, something other than a friggan spanner!
  • A good mechanic knows his/her limitations & calls on other people/businesses for help.
  • A good mechanic is committed to his trade for the long haul.
  • A good mechanic drives a 300hp+ v8-(ok maybe just a little bit of boganism)
  • A good mechanic never stops learning.
  • A good mechanic never brags
  • A good mechanic likes to help people.

How to find a good Mechanic

Whether you use my business or not here is what to look for.

Anyone who loves what they do wants to put back into the community. Trying to find some one you can trust & depend on is scary & takes a leap of faith.

Please do not blindly go onto marketing cheap sites, instead read.

Invest a bit of time learning about your car and be wary of reviews. Look deep in these reviews as the saying goes a little knowledge is power!

I hope this has helped.

The Dangers of Cheap Car Servicing

In our latest blog, we talk about the dangers of cheap car servicing. Keep reading below to become educated in wanting the best for your machine.

Running a business is very tough & difficult especially during the COVID-19 pandemic businesses trying to get work resort to gimmicks & marketing companies to try to get themselves work.

If you do not care about your car then go onto the marketing website & click onto the loser businesses that cannot market their own business.

First let me say this:

“Nobody of Business does something for nothing. There is always a catch!”

To use a shady shop a docket from a supermarket receipt & expect that service to only be the price that was originally advertised is naive at best!

When customers insist on cheap servicing or try to screw businesses down to pay less or supply their own parts, but want high quality work are delusional fools & personally I do not want them as customers.

This type of customer just mentioned, does not really respect or understand the complexity of cars. 

The dangers of Cheap Car Servicing

Since 2006 cars have become very complex.  components are more precisely manufactured & machined with finer tolerances they rely on quality well filtrated lubrication (Variable Camshaft system is an example).

Quality synthetic oil is expensive- this is no gimmick & quality oil filters is a absolute must. I cringe at the crap filtration components my opposition use- cheap crap- I recently had a shady salesman trying to tell me how much profit I can make using his no brand filters- he was abruptly exited out of my business with my a steel cap  boot strategically positioned at his google one star.

Air filters- The use of cheap rubbish air filters is like letting sandpaper- wear away your engine.

Fuel filters –The use of cheap fuel filters allow moisture & algae to block fuel injectors- this is critical with diesel.

Marketing Companies

Marketing companies are similar to car/life insurance & travel accommodation companies- they use the same format- cheap, save you money is their selling point- while slugging the loser business with a percentage. The other issue is that take all your vital information & get paid by the loser workshops & yet do not do any of the work! pretty smart heh!

Cheap Car Servicing

Cheap servicing at a shady mechanical workshop is desperation at best. The shop a docket should be a record of what you bought at the supermarket or used as toilet paper.

It is ironic that businesses that use shop a dockets get so many bad reviews. Hey people what do you expect, something for nothing? 

Cheap servicing is just a front so that the business can upsell you on other components to try & make up for the loss of the initial service . All while using the cheapest rubbish oil & filtration components.

Yet the most vital running components which actually propel the vehicle is lubricated with inferior components. This is stupidity at best.

What makes Manny`s Mechanical Repairs different?

  1. We like to help people.
  2. We love making cars go better.
  3. We use the best oil, The best filtration components.
  4. We use the best Diagnostic/Tuning/ Emission equipment
  5. We continually learn& grow- develop- better skills-THIS NEVER STOPS!
  6. By continuous disciplined servicing we ensure you get the best market value for your vehicle making your ride a profitable asset not a unroadworthy liability.
  7. Probably the most important point is my customers are friends- not customers,

Why you ask? Because we all share the same passion which is getting the best results for your car!

Getting Ready For A Road Trip

As the COVID-19 virus starts ease in Australia, many of you are eager to get out and about again. We have put together this blog with helping you get ready for a road trip when the virus lockdown is lifted.

As the world is dealing with this Covid -19 virus, Australia has been lucky to be an Island nation. Actually we are a huge Island nation.

Australia is ¾ the size of North America with only 26 million people compared to America`s 300 million, So we have vast distance with miles & miles of road.

Travel Restrictions Easing

As I write this blog The Federal Government is starting to ease travel restrictions.

Which means a bit of freedom at last, while the Aviation industry is still grounded, 

People will start getting into their cars & go for a road trip. Anything to get out & get some fresh air.

First – How far is the trip?

How far do you want to travel and what type of roads and terrain will you be driving on and in?

100km, 200km, 1000km, 2000km or possibly over 5000km.

Second – Is your car up to the challenge & load required for such a trip?

Example – I cringe when I see people go on a long road trip with a 18 year old car with over 250 000km with no accurate service history.

Simply the car is old, Yet for a turbo diesel Toyota Landcruiser, this is nothing.

 What you really need is a accurate assessment of your vehicle for the trip ahead.

Why You Must Keep Your Car in Safety Certificate Standards

Car accidents takes an average of 300 lives a year on Queensland roads alone (Nationally around 1200 lives are lost) and that’s why you must keep your car in Safety Certificate standards at all times.

If you use the 80/20 Pareto principal this then turns to average of 1150 serious accidents on Queensland roads per year.

To think this cannot happen to you is naïve at best!

Car Accident Investigation Team

A car accident where there is a serious injury or worse will call in a Accident Investigation Team who use facts & logic of some 1000 or more points to find out the exact cause of the accident.

Generally, this is divided in categories of –

  • Driving characteristic or error
  • Environmental – Bad roads, poor visible signage
  • Mechanical defects

The investigation provides accurate Data which is passed to Local, State or Federal Governments, The Police, The Department of Transport & Insurance Companies.

Car Safety Certificates

As the driver you are responsible for the way you drive & for keeping your car in safe standards without faults.

If by chance a mechanical fault is the contributor or cause of the accident, then the insurance company may not give you a pay out for your policy.

Simply go into any Car Insurance Company & read their Terms & conditions.

“How do I know if my car is in Road worthy or Safety Certificate Standards?”

Good question.

The Answer is you do not know unless you have a proper Safety Certificate Examination by a qualified Examiner.

“But I just had my car serviced it should be ok shouldn’t it?”

Should is a dangerous word because it`s not based on facts.

 Truth is a service is not a inspection its merely a routine of maintenance done at different levels depending on the skill (or lack there) of the service technician & how much you are willing to pay.

If you take car to a tyre shop or a muffler shop or get cheap shop a docket specials or use a cheap undercutting marketing website or worse use a cheap lazy mobile mechanic who is so lazy to jack up your car (the ‘she’ll be right mate’ attitude will not be good enough).

You are only deluding yourself & opening up yourself for serious consequences in the event of a accident.

Why You Must Keep Your Car in Safety Certificate Standards

As a car owner:

  • I would demand a thorough safety inspection on my car at every service with a written report & signature
  • I would demand to know who is working on my car?
  • I would demand to know what credentials has this technician.?
  • I would demand to know has the workshop the appropriate equipment & what quality parts are you using & are you using the correct oil.
  • I would get clear & concise information on what has or has not been done to my car written down in a clear legible manner with signature.
  • I would demand the best I can afford.

Manny`s mechanical repairs specialises in excellent thorough inspections with every service. We also record your emissions, computer scan every car, load test batteries, record battery charge & alternator output we thoroughly go over your car can also measure torque & horsepower!

When it comes to your car or that for your children who are driving – pay for the best, it may save your life!

My favourite saying is this:

‘If you cannot measure it, Then you cannot manage it!’

Only through Periodic systematic organised transparent checking can you be assured your car is safe.

Emission Testing North Brisbane

2020 has started with ridiculous heat, a national drought & terrible bushfires in Victoria, New South Wales & parts of South Australia. 

Not a good time to take a holiday in Hawaii..

Due to these events that have just mentioned, here at Mannys Mechanical Repairs, we have decided to lead the charge with implementing emission testing North Brisbane.

This testing will happen on all vehicles when serviced & repaired and on safety certificate inspections.

Vehicle Emission Testing

We have just upgraded on a new Gas Analyser to measure vehicle emissions on Petrol, Diesel, LPG & Natural Gas-

We can supply a print out on the state of your vehicle emissions at idle (sitting in traffic) & at 3000 rpm (cruise modes).

CO: Carbon Monoxide

The combusted dangerous gas that can kill in high concentrations. The lower the reading the better generally we are looking less than .5% with a good catalytic converter this can be down to 0%

HC: Hydrocarbons

is the unburnt fuel- left in the combustion process- This is a major polluter & effects the ozone layer. Hydrocarbons are measured in parts per million (ppm) the lower the better!

Co2: Carbon dioxide

Carbon Dioxide is a result of the combustion process- the higher the percentage the better combustion process which means the engine is running efficiently- still high levels of carbon dioxide cause Green house effect – possible global warming

O2: Oxygen

is measured- excess level of oxygen means there is a possible exhaust leakage which can effect emission readings or a engine fault. Though the gas analyser is a balance system- if there is a abnormal reading it will show irregular readings on the other settings.

NOx: Nitrogen oxide

This one is the bad one- a mixture of nitrogen & oxygen added with fuel hydrocarbons(Diesel)  Nox is released under extreme combustion heat- To combat this manufactures add a EGR- Exhaust gas recirculation system to cool & lower NOx .

 NOx gases causes Acid rain & Asthma.

Lambda & Air/Fuel Ratio

The ideal air/fuel Ratio for petrol is 14.7:1, Diesels can range from 14.5 :1 to  20 :1 That is 20 air molecules to 1 fuel molecule. lambda is a nominated reading by the engine software calibrator but generally a lambda of 1 is 14.7 :1 reference

Emission Testing North Brisbane

By reading the above, you can be assured we take our work seriously.

Global Warming is serious stuff and we can do our part to ensure vehicles are properly serviced, tuned & keep the polluters off the road.

 Manny`s Mechanical Repairs is leading the way!

“IF YOU CANNOT MEASURE IT.. YOU CANNOT MANAGE IT!”

Let’s make Greta happy!

Ford Specialist Enoggera

Manny’s Mechanical Repairs is your Ford Specialist Enoggera. We specialise in servicing, repairs and tuning.

Fords I Have Serviced

Ford Ba-Fg XR6

The “Barra” is probably the best engine built in Australia. After the disaster of the AU in late 1999-2001, Ford came bouncing back with the Barra engine, Dual overhead cam; then added with a turbo this engine became legendary & still is sought after today.

Huge power can be gained from this 6 cylinder master piece.

We here at Manny`s have fixed issues with variable solenoids, ignition issues, fuel pressure regulators & faulty injectors. Check past videos

The Boss V8

The XR8- 5.4 litre double overhead cam is my personal favourite. Nothing beats low down power like a V8, but these engines need tweaking.

Extractors, high flow exhaust, under size pulley; we have all the equipment & the specialized tooling to tune & replace the dreaded rear end differential bushes, tooling to support the engine & fit extractors & tune your vehicle with SCT Software.

FORD XR5

This 5 cylinder Volvo Duratec engine hot hatch is a favourite.

Issues with alternators, Cooling system, timing belts are no problem with Manny Mechanical Repairs.

Ford Mondeo – Turbo diesel

The Ford Mondeo is one the best cars that came from England. This turbo diesel vehicle handles smooth & has great fuel economy.

We have all the specialised equipment to service, replace timing belts & high pressure pump test equipment to keep this classic going.

Ford Focus- Petrol & Turbo diesel

The focus is a good little car. We have had to deal with issues with cooling systems, leaking radiators & cracked header tanks. With the Turbo Diesels we have had to replace high pressure fuel pump & a lot  of issues with catalytic converter pressure diaphragm sensors.

We have dedicated equipment to replace timing belts.

Ford Fiesta

The Ford fiesta is a great little budget car. Common issues with the fiesta are; overheating (due to seized thermo/radiator fans), thermostat housing leaking, header tank cracks & radiators leaking, engine breather bypass hoses deteriorating effecting idle issues & Fuel economy.

What is a Catalytic Converter?

The last two blogs have been about air flow at high engine speed through variable valve timing(  keeping the intake valve on longer @ higher speeds) The other blog was on precise relation & correlation between the valves and crankshaft through a timing belt.

Today I will talk about Catalytic Converters.

In the last 6 moths a number of customers have come into the workshop & Mannys Mechanical with the engine light on. Once scanned the dreaded fault code P0420 Catalyst system below threshold has been recorded. What does this mean? and why is it so expensive to fix?

What is a Catalytic Converter?

In 1986, Australia outlawed anti- knock agent Tetraethyl – Lead made it compulsory for cars to use Unleaded petrol. Also cars were fitted with catalytic converters in the exhaust system. A catalytic converter converts harmful unburnt fuel (hydrocarbons) into a inert gas.

A catalytic converter uses precious metals to react with the incoming exhaust gases in a ceramic monolith with a honeycomb structure.

The catalyst itself is most often a mix of precious metalPlatinum is the most active catalyst and is widely used, but is not suitable for all applications because of unwanted additional reactions and high cost. Palladium and rhodium are two other precious metals used. Rhodium is used as a reduction catalyst, palladium is used as an oxidation catalyst, and platinum is used both for reduction and oxidation. Ceriumironmanganese, and nickel – this list pretty well explains the expensive metals used & hence the cost.

There are a few different catalytic converters – a two way & three way. For catalytic converters to be effective the temperature must be around 426celcius. Which is why they are usually incorporated in the exhaust manifold & this is also the reason why oxygen sensors also have heating elements.

The picture above shows Kamahl holding a brand new Catalytic Converter incorporated with engine pipes to suit a Subaru Outback $2698.00 – yet they sell on Ebay for $400.

Would I buy from Ebay?

Not in your life. You will be lucky to get 4 months before it fails again. Heaps of after- market cheap rubbish do not use the precious metals listed above to last.

What do they mean P0420 Catalyst below threshold?

Generally there are two Oxygen sensors – a pre-catalytic converter & a after catalytic converter. They do a few jobs (Look at KAMAHL holding the cat` you will see one small hole and a extension where the oxygen sensors fit)

  1. They monitor how much oxygen is in the exhaust emissions and they measure is the catalytic converter reaction buy monitoring the change of state (threshold). If  the post cat sensor mirrors the pre-cat sensor, then the catalytic converter is not doing its job the fault code P0420 is registered. This information is monitored & compared through the computer in a term called closed loop.

What Causes the Failure?

There are number of reasons that can cause failure of a Catalytic converters. Vibration is probably the biggest killer. Exhaust systems have engine pulses which travel thousands a time a second these pressure waves can eventually break away the inner supporting structure-excessive over-fuelling through poorly tuned engines, coolant is one of the biggest killers- when a vehicle excessively over heats causing coolant to get in the exhaust system. Age, I am seeing vehicles around the 10 year mark coming in with this problem/fault code.

It’s so expensive to fix should I worry about it?

Well Yeah! When engine and emission lights come on, your vehicle is immediately un-roadworthy & if these hooligan climate activists have their way about climate change (running around half naked chaining themselves to toilet blocks & moving TRUCK WHEELS) will eventually  force Governments to crack down on vehicle emissions.

This could mean you, the car owner & me the automotive repairer will face some serious fines if the repairs are not carried out immediately.

What this does do?

It puts serious stress on. Say single mothers  to get their cars fixed straight away, whether they can afford it or not-..I would love to check  the car emission status on all these screaming activists & see how well kept their cars are- people in green house glass houses should not throw stones!

I hoped this has helped- Manny

What are the VVT or VTEC Letters on your car?

The last blog the topic was on the timing belt & the importance of the correlation of exact timing between the camshaft & crankshaft. In this blog, we explain what are the VVT or VTEC Stickers on your car.

The key to engine power is air flow/air density. The trick is to get as much air molecules compacted into the engine cylinder as possible when the piston goes down the cylinder on the induction stroke.

The pictures below shows a easy pathway for the air to travel (In this great cutaway example). The more air the greater force generated on the piston during power combustion, resulting in more torque at the crankshaft. The amount of air filling the cylinder is known as volumetric efficiency. 

VVT or VTEC Stickers

The intake valve is the gate way for air entering the engine cylinder. This is the V part of the initials in VVT. The valve is controlled by the camshaft either directly on top or by a push rod & lever shown by the different example photos. The camshaft has two important roles:

  1. It lifts the valve off its seat to a specified distance (valve lift or valve curtain area)
  2. It keeps the valve open for a certain time (valve duration)

 So all this thermodynamics is good but the problem is volumetric efficiency described above.

Most car engine revolutions (revs) about 7000rpm the speed of the piston is so fast that there is not enough time for enough air to fill with cylinder in milliseconds, so eventually the engine runs out of air at high rpm resulting in loss of power.

Then in the late Eighties Honda came up with Variable cam shaft profile. This is the other V in the initials. In the late eighties the Honda engines were so good with immortal drivers of Ayrton Senna , Nigel Mansel , Alain Prost, that they kicked butt out of the opposition.

The Variable part allows the camshaft to open the valve longer & even higher at different rev ranges also by being able to control exhaust valves emissions. Technically the intake valve can be opened longer at precise high engine speeds allowing more air to enter the cylinder. The volumetric efficiency as described before can go higher than a 100% normally aspirated, but add a good turbo like Honda did back in the 80`s, they were getting over 1000hp from a 1.5 litre engine with over 160% efficency!

There are many variants of control applied in The Variable Valve Timing (VVT). The most common is oil pressured phasers which are computer pulse width activated via a oil pressured activator. The Hondas use a pin locator and Holden use a special lifter to deactivate cylinders in their AFM vehicles.

VTEC Car Maintenance

If you have a car that has VVTOR VTEC, well then use good quality synthetic oil!

The trend of car manufacturers is to make smaller capacity engines which mean lower emissions but with excellent power output.

What are the VVT or VTEC Letters on your car?

Variable Valve Timing is now nearly in all makes & models.

Manny`s Mechanical  Repairs helps you understand more about your vehicle.

We invest in the best equipment, we go to the best courses, we continually use the best parts, the best oil & use the best skill on your car.

I hope this has helped.

What is Timing Belt?

Have you ever wondered what a Timing Belt is? 

Engine breathing & more important air flow is the heart & soul of good performance of a internal combustion engine.

How a Timing Belt works

I have selected 3 pictures to try to capture the job of a timing belt. The quintessential word here is “TIME”.

A brief run down:

In a nutshell the engine is a air pump with a piston moving up & down. The down speed of the piston causes a negative pressure (vacuum) and air enters the chamber via a intake valve (this can be through one or two valves) –  Induction Stroke.

The intake valve closes at a precise time, when the piston moves up it compresses the air & injected fuel (compression stroke) and the spark plug fires, causing a combustion process resulting in a flame front & high pressure. The combustion pressure forces the piston down at a precise time sending torque down the crankshaft turning linear force into rotating torque (power stroke).

As the pistons ends the downward travel, the exhaust valve opens at a precise time. The piston then moves back up pushing exhaust gases out the exhaust valve (exhaust stroke).

Why Do I have to Replace the Timing Belt

Timing is the issue & it has to be precise. To open & close valves at the precise time in relation to piston position, this requires a timing belt. These timing belts are due to be replaced approximately every ten years or at 60 000km – 100 000km. Some makes have different time intervals, so please refer to your repair manual for the exact times.

Stretched timing belts can throw the whole series of engine stroke events totally out of sync with the valve events, resulting in poor performance, poor fuel economy even possible engine failure!

Why so expensive to replace?

Replacing timing belts should also incorporate replacing the water pump. Some vehicles may require the engine to be removed from the car to replace the timing belt.

Many manufactures require special holding and locking tools to hold engine components in the exact position to install the belts. This can be very expensive just to get the right tools to do the job.

What is a Timing Belt?
