    Default Oil Coolant Line Leak at Filter Housing

    Hey guys, new to the forum and excited to be here, hopefully I can gain and give some knowledge and ideas. Now down to business, I'm sure this has probably been discussed on here before, so hopefully someone can point me in the right direction. I've recently bought a 93 burban as a toy, radiator leaked so when I replaced that, I also decided to replace the oil coolant lines. Now I've got a leak on the top line and I can't get it to quit!!! New line, clips, O ring. Anyone have any other ideas????

    Leaking at fitting? At trans or radiator? I am assuming transmission oil cooler in radiator.

    It's the engine oil cooler, located on the oil filter housing.

    sounds like you need an adapter housing gasket set. a few o rings if it's like the old 350's
