I have noticed recently that after driving our 2006 Equinox for a little while and then parking in the garage, it smells like old dirty oil. I changed the oil recently and didnt notice anything abnormal like chunks or similar and there's no leaks. Its the 3.4L and has 80k on it so I was thinking maybe sludge but pulling the oil cap looks normal down in the valve train. I do notice occasionally the remeniscant, short lived sound of a Cummin's diesel engine when it starts cold. The only other thing I can think of is excessive blowby but I don't know how to diagnose that.
