Guys I am back :D, and I have something to ask regarding the 330D E92.
The E92 330D comes with 2 engines, the M57 and the N57.
The M57 is the one that was used in the E46 330D (which a friend made over 300,000 KM on it) made of iron and as far as I know it's bulletproof
And the N57 is the new one made out of aluminium, much lighter with less emissions.
However I heard that the new N57 shares the same timing isues with the other N series like the N47, N46, N42 etc. And they even put the timing chain at the back of the engine, so more labor and bigger problems.
While the old 231 HP M57 doesn't have this timing chain issue and the timing chain is at the front. Also has bigger emission (which I don't care, no emission laws here).
So what do you guys think, will the M57 be a better option than the N57 engine?
Are there any actual drawbacks of the M57?
