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.

What is Your Hourly Rate?

It amazes me how many people ring me up for a immediate quote on a car which has major issues without giving me the chance to thoroughly inspect the vehicle and get a detailed analysis of what the real problem is. These penny pinchers ring one workshop after another until someone gives them the cheapest price possible. It’s easy to pick these type of people by their initial question- “ AND WHAT IS YOUR HOURLY RATE ?”

For a job to be done properly it requires skilled labour which is the backbone of any quality, successful job and the price has to be paid – YOU CANNOT GET SOMETHING FOR NOTHING!

Many years ago I took one of my ex-wives to court because she would not give information about the well-being of my daughter. In the initial interview with my solicitor, I stated my case and then asked “AND WHAT IS YOUR HOURLY RATE?” My Solicitor laid back in his plush leather chair, crossed his arms, squinted his eyes and barked back at me, “DO YOU WANT TO SEE YOUR DAUGHTER OR NOT?”
“OF COURSE I DO, WHAT A SILLY QUESTION” I said defensively,
“THEN GET THE MONEY & DO NOT ASK ME MY FOR MY RATE!”

Bang… Talking about getting hit right between the eyes, but his words ‘GET THE MONEY’ kept ringing through my ears and something miraculous happened, I kept focussed, worked harder than I ever did before and presto I got the money, won the court case and got to see my daughter.

Watching my solicitor perform in court with confidence and poise was money well spent.

Skilled labour in any profession or sport takes years and years of practice. It’s doing that counts, not study or reading books. Organised refined labour is what gets the job done.

And there are no short cuts. The price has to be paid in any profession.

The surgeon who performs microscopic robotic surgery; the bricklayer who can lay hundreds and hundreds of bricks perfectly; the doctor administering a catheter to give a patient relief; the mechanic who can tune an engine for peak power and good economy; the nurse who showers, cleans and puts fresh bed linen on to give the patient dignity and hygiene; our brave soldiers fighting overseas so we can have peace in this country… all this is skilled labour and the full price has to be paid.

This is why I hate reality home improvement or renovation shows. I believe these misguiding television shows have a duty of care to perform especially in handling asbestos, dangerous other materials and of course they do not show the tedious hard work that trained professionals do because this will be boring and we cannot have that-people will switch channels to Family Feud.

Here is the irony. People who have mastered their profession make it look easy!

SO WHY DID I WRITE THIS BLOG?

I will give you the answer. A week has just passed since another dreadful balcony has collapsed, killing and maiming people at a Christmas party. The coronial inquiry will get the answers, but how many more people need to die or be injured because of shoddy workmanship or unscrupulous people wanting renovations and not wanting to pay the hourly rate for work to be done properly?

Miserable people who systematically try to screw down quotes from struggling tradesmen are the biggest cancer to the economy. What this does is force the tradesperson to buy rubbish from China. China is a Communist government with a Capitalist business ethic and they deliberately hold their currency low so they can export their rubbish to the world, they have no shame or respect for quality.

I refuse to fit Chinese parts to any cars I repair (experience here) unless it a Great Wall.

Any person who tries to screw me for price or tries to manipulate so that I cannot do my job properly to a set standard is not one of my customers and will know it.

GET THE MONEY, GET THE JOB DONE RIGHT. IT COULD SAVE YOUR LIFE!

Capped Price Servicing – What is the Truth?

In my last blog, I talked about CONTINUAL IMPROVEMENT, how skills and an ongoing desire to be better is essential for better customer service without the gimmicks.. Which brings me to CAPPED PRICE SERVICE .

Capped Price Servicing was introduced by major car dealerships to try and reverse the poor customer retention rate which car dealerships created themselves through sky high servicing costs and poor customer service.
Their gimmick is simple – NO SURPRISES AND FIXED BASIC PRICE SERVICING.

Car dealerships do not make money selling new cars, their source of positive cash flow comes from spare parts, selling useless extended insurance and warranties (read the fine print), trade in cars (traded in at low price and sold high) and of course car servicing.

The truth is quality new cars do not need much service upkeep in their first 3-5 years or 50,000km which aligns with the dealership service plan. In other words they are only stating the obvious.

So what is the catch?

There has to be a catch right?

Car dealerships and franchises work on volume, while the profit margin is quite small, but because they do so many of these low skilled services (that’s how they make their profit) consequently brings a low skill technician. (I recently had one of these moron technicians working for me and let’s just say Hasta la vista BABY!)

The catch is cars are an ongoing load bearing rotating piece of a machinery. Anything that rotates on a car can and will wear. I WILL REPEAT THAT -ANYTHING ON A CAR THAT ROTATES CAN AND WILL WEAR. Tyres, fanbelts brakes, suspension, internal engine components, water pumps unless you park your car in a garage and let it sit there is the only way you can avoid wear and tear.

Pricing though important should not be the main focus to the diligent car owner. Now with turbos, direct injection and variable camshafts, it is critical to have the best oil, best tyres, the best quality filters. A dirty air filter can affect your ca’s performance, engine wear and fuel economy and yet is perhaps one of the most overlooked service component.

To the serious car owner your car should be looked at as a investment, no different to your home.

Your car is a vital piece of equipment, especially when it comes to picking up children from school, family and work commitments. Invest in your car. Do not  be swayed by capped pricing only to be  slugged like a wounded bull  when your service schedule is over or when your car is due for tyres and brakes.

Yes pricing is important, but a good quality technician who knows your car personally, has track records, works to a system and is totally open and transparent while using the best parts and has the best equipment WHICH HE USES ensuring motoring piece of mind.

Continual Improvement

Recently I was called by a concerned parent from New South Wales who had sold a car to her Son. The car was brought to Brisbane and had to have a safety certificate. The inspection was done at a competitor’s workshop and a failure was issued. The vehicle required $1,200 worth of repairs. The concerned parent was confused because their local mechanic had always serviced all their cars and HE SAID – THE CAR WAS OK… they trusted him… so who was telling the truth?

The vehicle was brought to my workshop and an inspection was performed and ‘YES!’ all faults were verified. My competitor did his job right and his quote was reasonable.

So where is the problem? The problem is with the old dinosaur/fart of a mechanic, THE GOOD BLOKE MECHANIC OR THE FRIEND OF THE FAMILY MECHANIC who has won over generations of family dynasties with his great bloke she will be right mate mannerisms – THESE MECHANICS SHOULD BE OUTLAWED and why? – simply one word… HUBRIS.

We live in a fast and complex world. Your car is more vital today than ever and your car is becoming more complex so reliability must be a high priority. No public transport, taxi or uber can take the place of a car when it comes to children and vital appointments which require to be met with in a set time.

A good technician/mechanic continually invests time in study and working to a system with a organized checklist. A good technician has the guts to invest money in the best diagnostic equipment $5,000- $40,000 a year whether he can afford it or not. A good technician analyses every car and ensures that it is up to safety certificate standard or gives a detailed report and quote what requires to be done. A good technician/mechanic FOCUSES ON SOLVING THE INITIAL CUSTOMER COMPLAINT and does not go for the easy upsells (easy money). Simply a good technician wants to be and is better every day, but most of all good technicians are committed and disciplined.

Just because a Dinosaur Mechanic says that he or she has 35 years of experience means absolutely nothing… what… 35 years of doing oil changes? Please retire.

Workshops that offer gimmicks, cheap heavily discounted services or have some other enticements are totally useless. The smooth talking service advisor who has not touched a spanner in 5 years is there only to sell and generally gives you a headache because they talk so much rubbish. These big mouths got out of the game because they are pretty boys that could not handle the hard work and discipline required to be good in their field.

The truth is nothing beats up to date hard earned skills, disciplines a systemised attitude of continual improvement and a genuine passion to be better educated for what they do and perform. Good technicians/mechanics are never satisfied because there is always a better way.
