2002 M1123 6.5 Oil Filter Housing Gasket & Oil Cooler Gasket

Hummer Guy said:

Does anyone have the NAPA part number to the oil cooler seal/gasket and the oil filter housing gasket? I have a small leak around the oil filter when the truck is running. I changed the oil cooler line about 2 years ago and the leak finally came back, I prefer to just replace the seals instead of the whole line

I’m not sure if I’m understanding your Question correctly, but the 90* adapter that the oil filter screws to has a set of gaskets. I bought this kit from HPG. I don’t believe the “kit” is a military part as I couldn’t order it from Mac motors.

$15 from HPG. My leak belowView attachment 948179
