MOT fail thread

Fuel efficiency, noise and I think the original expectation was the belts would last longer if anything :p

Good to see they did a thorough life test of the belts when designing them then. I'm sure car companies would use paper mache for doors if they could to improve emissions.
 
The belts do generally last well if the following is true:

If diesel, the DPF gets hot every run - so that oil doesn't get diluted with fuel when it clogs up
If service intervals are stuck to exactly or sooner
If service is only done with the manufacturer approved oil

However, if any of those things is not true then the belt will deteriorate and fail.
 
Engineers must have known running rubber through oil at high speed was a stupid idea, it's a terrible design. But it improves mpg/emissions figures very slightly, so the accountants want it.

No matter how careful you are with it I don't think you'll avoid some debris getting in to the oil. You will only extend the failure to a later date.

What do you think valve stem seals. And engine seals are made of?

Well obviously they aren't made of the same stuff and it's a well proven design. Wet belts are not...

We know wet belts disintergrate and destoy engines, that isn't even up for debate. You can't even check it easily to see how bad it is.

It really isn't worth the few quid one can get for doing dodgy MOT's, and believe me, plenty of people ask (and as happened the other day, and that guy was told by me to **** off and get off the premises).
99% of the time, it's always the same kind of people.

Just to add, if a tester completes a test in less than 30 minutes too often, then it's red flagged to the DVSA, and then they start to check ANPR records as to where the car actually was at the time of test, then they come down on you like a tonne of bricks.

Fraud which could get people killed. 16 weeks, suspended.... Weak. Also only banned from testing, but they can do other work on cars. Like pretend to fix things highlighted on an MOT.

There is a lot of this going on especially around those dodgy looking used car dealers you see tucked away on industrial sites.

I won't argue with you there.
We used to do work for quite a few small car dealers, but they can get very aggressive when we add advisories/failures.
Now we only deal with one, because they do everything that's advised or failed no questions + their cars are prepared properly.

An acquaintance of mine, bit dodgy himself to be honest, has a thing on the side of buying MOT fails cheap and bodging them through an MOT (he isn't the worst for it but I definitely wouldn't hold much to his quality of work or ethics) but he was saying the other day he has had a massive rise in the last few months of requests for 2 things:

-Dodgy MOTs (he doesn't do MOTs himself).
-People with two of the same make/model car wanting to transplant things like injectors, brake discs, tyres, etc. etc. which he has clocked as people buying a used car the same as their existing car which is in better condition than their own, swapping the better stuff over and then returning the car :( and/or then going back to the seller to get those things fixed at their expense.

I have a colleague whose allegedly done that with a Ford KA. Bought a better car and then swaps good parts into the bad one.
 
Seems to be the common scam when people sell on places like Motorway at the moment, couple of days later they start getting hassle from the buyer saying it's broken because they've stripped all the good bits off and put their crap back on it.

Anything dodgy around brakes or safety related checks should result in severe punishment!

I guess wet belts also have a massive surface area in contact with oil, are are under tension, seals typically are under compression so might be a large factor.

Theyre different materials subject to completely different environments and forces.
