I'm rebuilding my engine. The machine shop guys said replace the oil cooler, the local VW guru said its fine?
What should I do?

Assuming it isn't plugged, that is.
Also clean out and straighten the fins for optimal air flow.

I don't think the crankcase on this engine has ever been messed with, it has 74,000 miles

I would add... if it's not leaking, and it's original VW, then yes, keep it.

If it truly had 74,000 miles, I wouldn’t even be getting into the crank case!
If a factory oil cooler has not be run on an engine with a failure that lead to grit in the oil, I would reuse it until the end of time. Or until it leaks.
It doesn’t leak, does it?

No leaks maybe this sucker has 174 on it it was hemorrhaging oil. My vw guru pointed out to me the places oil was coming out between the cylinders and the crankcase. What is the best way to clean this oil cooler?

This ^ is an amazing sentence ...
Stick with the original cooler until it has provided you evidence that it is done.
I clean them with GumOut spray, shake, drain, GumOut, shake, drain, GumOut, shake, drain, until the drain runs clear.
You may want to pressure test it if you have questions about its integrity.
