Sorry to interrupt the flow of info guys, but I'm fairly new at diesels, can anyone explain to me or point me in the right direction on how you determine the amount of timing chain stretch one has on his vehicle? Thanks...

The 1990-95 six-cylinder 3.5L engines (OM603.97x) all have a stronger version of the head, and these very rarely have head or gasket problems. However as you probably know, *all* those 3.5L engines had weak connecting rods, which oval out the cylinders, requiring a MUCH more expensive fix - which is NOT a DIY project like the head. Luckily, the 3.5L engines provide good used heads for the 3.0L! :p They're scarce and not cheap ($800-$1200 typically, used, with cam & lifters if you're lucky).

I'd still like to know what the newer and better engine number is for the 3.5L engines. OM603.97what?

There is one at work here, W126, a white one, and I just love the car.

Thanks
