Its not cloak and dagger, its just that i cant just come out and say something bold because i will be shot down in flames by a few companies and attract the wrong sort of attention.
Tin foil hats everyone......
There seems to be a serious weakness in the pistons used in the EA888, they can crack and fall to pieces.
Now it can happen to anyone tuned or stock, it was looking like one tuner in particular was causing cylinder 3 or 4 to crack lowering compression significantly to cause misfires. But now I have seen cases on bone stock motors.
The cracking tends to happen on the piston edge and sometimes it is so minor it will only drop compression by half a bar, you wouldn't even realise its happened, the car will drive and perform glitch free for thousands of miles or maybe just ten before it 'goes' and requires a rebuild.
Its looking like VW are aware of the problem but in typical big manufacturer style ignoring it, the cynic in me believes this because they have got such a wide compression threshold for when they deem the engine requires a rebuild. So they wont touch it until the engine completely chews itself, this is because it might just last long enough to be outside of warranty.
So what do we do?
I suggest everyone worried does a compression test, if cylinder 3 or 4 are showing to be half a bar or less than the others.... shoot me a PM
Why is it only 3 and 4?
I have no idea, but i have seen about a dozen cases now and they have all been 3 and 4... mostly 4.
So there you go flame me down, call me paranoid or take the mickey because i used a science class term from saying newton-metres (i prefer ft-lbs btw)
