That's what the "word" was at that time; no talk of bad chains then, though.

If an original 3.5L OM603 engine has made it 20yrs/150Kmi and currently

Many did have issues though (usually just outside of the warranty, IIRC)
& I'm not sure if a definite answer of why this was occurring has ever
been found out.
The only theory I know that explains the fact that #1 rod is almost always
the first to fail is head gasket failure and oil going into cylinder #1.
OM601/602/603 always tended to get head gasket leaks at the front, the
larger bore of the 350 seems to increase the likelihood of the oil going
into the cylinder instead of outside the engine.
