Having problems with your 2001 Buick Century ?
Engine oil in the cooling system. flushed radiator, oil slowly coming back. no coolant is getting in the engine oil. does not seem to have any combustion gases in the cooling system. transmission oil cooler tested ok. do not have a engine oil cooler, or a power steering oil cooler. the engine is a 3.1 liter.
Sounds like a bad head gasket.
