Everything seems fine car has a complete service history from mazda since new there is 84k on it now . Am I in the clear at that mileage or is it still an issue
Thanks
As Steve suggested, get in touch with Mazda and demand the pucker history on the car. Mazda has an online system instead of the usual service book and the online system does not record any warranty work or in fact, any parts that have been fitted. All it tells you is that the car was serviced and that is all - which to my mind is not a 'Full Service History' by any stretch of the imagination! Car manufacturers have always been secretive, but not declaring information such as that should not be allowed. In this age of so called 'open information' the car industry is lagging behind - I wonder why?
It could well be that all the work has been carried out, however, if you bought the car from a Mazda dealer at a price that you considered to be cheap, then suspect that the work has NOT been done and at any time you could have a serious problem on your hands. Engines within the declared VIN range (which is not difinitive by any means) have known to fail at miliages as low as 20,000 and as Steve said, over 120,000. It all depends on how the car was run prior to you owning it. Lots of M6 Tourers were supplied to sales reps., managers etc. and even company directors, some of which thrash their cars as they know it's someone elses problem if anything goes wrong. If yours has an auto gearbox it's a good bet that it wasn't thrashed, however, to my knowledge, no survey has been done comparing number of incidents and at what miliage - manual GB to Auto GB - only Mazda themselves know those facts.
I don't know how much of this thread you have read, or if you are aware, that when this problem first come to light, Mazda themselves had no idea how best to deal with it. Cars with very worn camshafts were dealt with as per the dealers usual procedures - i.e. flush the engine once, fit new camshafts and away you go. It was only later was it realised that the vacuum pump and turbos were almost certainly contaminated with swarff (millions of tiny pieces of metal) thrown into the engine as the unhardened camshafts were in effect being 'shaved'. Those dealers that are lets say, more careful than others, decided to introduce a double or even triple engine flush, after checking all the other parts of the engine for 'swarff'' and in some cases this did the trick by flushing out all the metal debris.
It is also known that some dealerships, mostly those that sell and service other makes of cars, use synthetic engine oil, which to these new Mazda engines (2012 onwards) is pure poison, as it corrodes the rubber rings and seals. Those vehicles filled with that type of engine oil have had DPF problems as well as loss of power and early engine wear, whether they have correctly hardened camshafts or not. The 2017 user handbook actually says that only the Mazda approved engine oil must be used, however, as already stated, most Mazda dealerships sell other makes of cars and service all makes the same way - i.e. engine oil is generic and is stored in a central tank.
was talking to two airheads who'd no idea what a camshaft and couldn't even tell me what warrantee work was ever carried out on my car
