Can't find my engine serial number

[RoadTripper2084]

At the risk of looking foolish, I can't seem to locate the serial # tag on my Cummins C8.3 engine.

I figured lots of folks here probably know exactly where I should look.

I have the C8.3 engine, which I believe is also known as the "6CTA" series.

This is what Cummins says about it:

I can't really access the spot on the top of the left-side of the block, I took a few pictures but couldn't see anything.  They mention that "the long narrow metal tag is attached to the front cover/gear housing...".  Any ideas where I would look for that?

Your picture looks like for a 5.9 Cummins 

 

I believe my data plate on our 8.3 was on the front cover top near where the oil hose attached. To looking at engine from rear of coach, it’s top right

Yes up behind this area on the top right if I remember correctly. Looks like this
