OM603 with #10 casing?

There have been posts concerning the #14 series OM603 six-cylinder engine heads, and their apparent greater tendency to crack. However I'm looking at a car that has a number #10 as part of the casing number, and I'm mystified. I was under the impression that #14 was the original, flawed series on the OM603.

Any of you diesel maniacs have any insight into this mystery?

Thanks,

Peter4

The casting number that is referred to is the second to last group of two digits. Most of the heads have the last two digits as a "10"

The "14" would be the number just prior to the "10".

It could also be a "15", or a "17" or a "22".

Mr. Carlton may have it right. I did specify to the seller to look at the two digits preceding the last two, but he may have misunderstood me!

It's amazing how quickly people respond on this forum. I think I was right to use the term "diesel maniacs."

Then again, Mr. Carlton might be wrong. The seller sent me the full number on the casing which is:

603 070 10 01.

The mystery is still a mystery.

If the seller is looking at the proper place on the cylinder head, which is right above the #2 injector, below the crossover pipe (you need a mirror to read it properly), then you have definitely got a head that we have never seen before. If that is truly the case, go back and read post #3.

Just make sure he is reading the number off the head and not off the crossover pipe or somewhere else on the engine.

Maybe the seller has bad eyes and is mistaking a 0 for 8? 14's were the original their is no lower number.
