I had the M157 5.5 Bi Turbo and I know of 3 other owners - none of us had any issues , not exactly a cross section but....Having done a bit of research on this,it would seem the engine would need the additional oil check valve,tensioners and guides fitting according to the mercedes tips(from 009368 to 017984)
In reality,how common a problem is it?
And how much to have the tensioner and guides fitted?
The car has fmbsh and relatively low miles(58k)
