Thread: losing antifreeze and exhaust fumes in overflow and idling ruff

Bad LIm usually put oil in the radiator, what connects to the LIM? EGR, hence the smell. That's what would make me look at the LIM.

Would you mind explaining how the LIM gasket where oil doesn't even pass through it can put oil into the radiator. Let alone the only oil possible to be near the lim gasket has zero pressure because it's returning to the oil pan and the coolant is pressurized to 16psi.

PS..I'm looking at you with one eye cocked and wondering....can I have some of that stuff you got?

O_o Wut u talkin 'bout Willis?

Rico, I talked to Bill about this in chat. My diagnosis was based on experience with an N/A 3800 in a 95 olds delta 88. Had oil in the coolant, not red, grey. LIM gaskets were toast, did lim and uim gaskets flushed the coolant system and have run the car over 20,000 miles with absolutely no problems since. I understand the coolant system is under pressure, I can't come up with any other explanation for the problem though, if it was head gaskets the oil would have showed back up in the coolant, it hasn't.
