1992 Cadillac El Dorado Repair Question
ENGINE KNOCK 1992 Cadi Eldorado 4.9L
Here is what my oil cap looks like? I see some white on the cap, but when I look inside the engine or pull the oil dip stick, it all seems fine...
Here is the engine:
I have been told things like a head gasket, leak in a manifold, pull spark plugs to look for water, exhaust leak??? Can anyone please give me more information?? THANKS MUCH!! Marty
The radiator, if the tranny cooler lines attach to it, can leak tranny fluid into the radiator! Check your transmission fluid! If you have a small bit of white oil on the cap, change pcv! As for the knock, connecting rod or wrist pin!

man oh man, if coolant is getting into the oil, the intake manifold gasket is leaking, remove the valve covers and pressure test the cooling sys to check this and if you have a knock from it replace the engine dont let someone replace the gasket it will cost you more in the long run
