Another typical problem with 603 engines is failure of the head gasket between the timing chain gallery and #1 cylinder. In that failure, engine lube oil is pumped into the #1 cyl. Massive clouds of oil smoke and sometimes lube oil coming out of the tailpipe but no loss of coolant or residual cooling system pressure.

I run a "603 engine" it is one of the best and most reliable car engines anyone, including MB, have ever made.

I am talking about the venerable naturally aspirated 603.912 of course, but it is still a "603".

It is imperative that people get their facts right, which always means avoiding all abbreviations and short-cuts, of which this "603 engine" is a classic example.
