Where's my engine number?

Where's my engine number? Got one on the timing gear housing, but..... Where's the OTHER one?? I want to compare the 2 and see if the short block has been changed out like I was told. If they changed the short block and kept the same timing gear cover, the numbers will be different. If the block is the original one, the numbers will be the same. Cummins says something about the oil cooler, but I can't see anything. Here's what they say:

"NOTE: If the engine dataplate is not readable, the engine serial number can be identified on the engine block on top of the lubricating oil cooler housing. Additional engine information is available by reading the ECM dataplate."

Now, I can see the oil cooler, just not the engine number. It's supposedly on top of where that oil filter bolts to the block. But I see nothing there. Do I need to take a toothbrush to it or what?

They may mean the oil to water cooler for the transmission that is under the exhaust manifold.

Also, read the quote you posted again.... "Additional engine information is available by reading the ECM dataplate."

My ECM dataplate fell off and is hanging on the wall in my office. I believe it has the ESN on it, but in the event that they did a shortblock it is almost certainly the same ECM.

Might be worth a try. I'll look at it. Does yours have the ESN on it?
