601-1363 napa SBC oil cooler gasket kit

[tompumped]

I just replaced an old motorcraft oil filter gasket that had maybe 50 thousand on it which I used to seal the obsolete gasket for the oil filter cooler to block. I purchased napa 601-1363 and apparently in the kit there is one red o ring that fits best.

The red one fit better than the black one of similar size. I guess i'll find out if it lasts. The motorcraft gasket had to be retorqued at one point, because the oil filter bolt was so loose I could turn it with my fingers.

I had no idea rubber can flatten that much and take set. When I pulled that gasket today it was the thickness of the original but the rubber was smushed out the sides.

The head in that location almost completely dried out a thick oil filter gasket in short time. I'd like to believe the o ring I just installed is of better material.

The oil cooler has a metal "standoff rim" on the back, so when you find the right size and thickness of the rubber gasket the "rim" of the oil cooler is tight against the block so as to keep the bolt tight.

I've done it twice the other way and both times I didn't use the correct procedure to rig it, by botoming out that lip. I was underneath and I didn't see the oil cooler bottoming out, resulting in improper torque. They did last though, but I retightened them once each.

Hi Tom,

Is your red O-ring you put in your oil cooler from the NAPA kit seems to hold well since 2015 ? (Mine had started to leak a little bit...)

Thanks,
