Have water in the oil on my 1993 400e. I'm assuming it is a head gasket, or do these cars have another common failure point that might cause that? If it is a head gasket, the parts store has 2 different engines on file 010591 and 010592. I've looked high and low in the engine bay to figure it out, where is the number located? I just recently bought this car and it doesn't run so I'm slowly piecing it together because otherwise it's in great shape.

Thanks in advance and I look forward to learning on this forum!

How does this reference to the 010591 and 010592 numbers on the parts store engine list?

The numbers your are referencing are EPC footnote numbers both for a left side head gasket.

There are 2 foot notes in EPC for the part numbers, 029, 030, Each footnote comes up with a different number similar to the ones you show.

and there are actually 2 different part numbers per side

See my screen shot of EPC footnote 029

EPC can be confusing when there are several choices to make for the same PN type.

I would go to a Mercedes dealer with the VIN, and let them tell you which ones are the latest and correct P/N's.

I have read in forums to avoid removing 119 V8 heads at all possible costs, it is said to be a huge job, and not for a beginner DIYer.

I would make damn sure the problem is the head gaskets before tackling this project..

personally I would look for a dependable Indy mechanic who is experienced with 119 motors...good luck

N update numbers.

Thanks for the engine code advice, everything has to be so difficult! So I held off on the head replacement, though it does look easier than I imagined. Running it a bit with some new plugs, and some injector cleaner to see if the cloudy oil returns. I will say now that it any runs, anything above 15 mph is super impressive!

The M119 is really an easy engine to work on....
