Oil Cooler Fitting Seals

[tom_sprecher]

Did you weld aluminum fittings onto the cooler thereby eliminated the flat area and seal altogether?

At this point the cooler is junk and it should work fine after that.

Just replace it. Check out Pegasus.

or like someone else said 2nd gen cooler, check out car-part.com. Around Pgh, PA there were several 2nd gen coolers ranging from $50 to $150.

After doing what you described you described in the first post without even thinking there would still be a crack running the length of the threads on the inside and having the cooler leak again we tossed it in the trash and threw a 2nd gen cooler on the car. We had 3 or 4 sitting on a shelf so it was a no brainer. Even if you have to buy one they can usually be had for $50 or less. The inlet and outlets aren't as convenient in the 1st gen chassis but it's not a deal breaker.

If I had a sentimental attachment to the cooler I'd start by welding the fittings to the bung as well as repairing the crack. Will be the only way to stop the leak for good.

Welding did not work as the end tank was too corroded and difficult to clean where the bung and end tank get real close. I tried to get another one today but it turns out what I have been using is actually a RX-3 oil cooler and the 1st gen unit is about 2 inches longer. With the way I mount it there is no way it will fit and I really don't want to re-fab the mounts and duct work if the 1st gen unit is prone to cracking.

I'll see what I can get aftermarket wise, but I think this kills my chances of racing this weekend at Road Atlanta. There's not enough time to get everything and make it.
