Here is some good info on the Oil cooler by Genscriptor.

I went through the Oil Cooler puking oil into the Cooling system a few years back.
Better to do the new "O" Ring and paper gaskets with the engine sitting in front of you.
There is a metal tab on each end to pry off the end caps.
I polished out the inside of the caps with some very fine wet/dry sand paper maybe 1000 grit, to make sure there was nothing to nick the new "O" Rings.
I used my 20 ton HF Press and Syl-Glyde for the lube get the them to seat. Did one end at a time, with lower end on a piece of hard wood I had. Just make sure you are pushing on even and straight.
If the end caps aren`t perfectly lined up, they will rotate.
I found a remanufactured MC Cooler, one on RA and the other on Parts Geek. Now all I see are the Dorman Coolers.
Might be a good idea to remove the bolts on the valve Covers, blow out the holes with Carb Cleaner, and blue Loc-Tite them. Seems to keep them tight longer w/o the oil leakage.

Came across this oil cooler thread in one of my folder of saved stuff.
