Good on you for fixing it yourself...no matter how getto it might be. :wink:
Thanks for that idea of using gasket sealer, I had same problem and used some gasket seal over the old gasket that was cracked in 2 spots that caused the leak, all good now. That area of the oil cooler is a pain in the ass to work on! 😬Figured I would update on this problem. I gave up with Hyundai and their warranty, pulled the oil cooler myself and cleaned it all up. Oil cooler was fine with no damage. I wound up using a small bead of liquid gasket along with the original rubber O-seal (ghetto i know but why not)......couple thousand miles and no leaks. Ill never understand why the little rubber seal that is on the cooler cannot be purchased separately. I found a few oil filter gaskets that almost matched but decided it was not worth the hassle.
