Engine problem
2002 Buick Rendezvous 65000 miles
----------------------------------------------------------------
Recently, my engine overheated and the heater stopped working. I took it to the Buick service shop last week and was told I needed to replace the intake manifold gasket as it was leaking (I had almost no engine coolant). The shop filled it up with engine coolant on Friday last week and I scheduled an appointment to have a new gasket put in Thurs this week. On Monday this week, the car overheated again and I needed to add another gallon of coolant. I didn't drive the vehicle again except for taking it to the shop this morning. I got a call today saying that the engine oil shows signs that engine coolant has leaked into the engine (the oil appears as a chocolate milk-like substance). The options given to me are: 1) replace the gasket and hope that this solves the problem, 2) inspect all cylinder heads for cracks and replace as necessary or 3) replace the engine to the tune of $5k. Needless to say, none of these options are particularly attractive to me ... what concerns me even more is I'm not confident that the Buick service shop has properly diagnosed the problem. Help!
