1995 Saturn SL1 Question: i have Oil leaking into the antifrezze?
i have oil leaking into the antifrezze causing a gray sludge and overheating..i have taken apart the engine and the headgasket is fine..wut else could be the problem...and there is no out side cracks on the block? - Visitor
most cracked blocks you cannot see the crack with your eye. the bottom line is you need a motor replacement. Roy - mastertech6371
It's common on these engines to develop hairline cracks at the camshaft journals. When the engine / cyl. head warms up the crack(s) will open allowing engine oil mix with coolant. You can fix this problem by replacing the cylinder head assembly. There is a TSB describing this problem. If you post an e-mail I'll look for it and send it to you. Zee - ZeeTech
have you checked your oil cooler in the radiator? It can cause the same problem - Visitor
