OM603 with #10 casing?

[Peter4]

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,

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".

Get out of here Really????

Hay, maybe there is a #10, how is it that they started with the #14? Where is 13 12 11 10 9 and so on down, hmmmmmm???? BB

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.
