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????
