1992 535i w/Dinan enhancements 6 cyl 5 spd. I just noticed oil in the coolant kind of a blueish grey. I have no performance issues, no water in the oil, or sign of water in the oil pan, it's been running great .
From the forums I probably have a oil to coolant system leak in the head gasket. ( Mechanic quoted me $800 for flush $2100 for gasket)
Is the a best practices for flushing the cooling system?
yes true blue and Bars Leaks looking for a how to guide?
