There is no mix of coolant and oil. It goes away after warm up. I am thinking that it is condensation in the exhaust. Last night the exhaust had a rotten egg smell. It did not do it today though.(Yesterday was warm, Today was colder?)
I put some fuel system cleaner in it and filled my tank last night.(I was on E-nough driving)
Any ideas on the cause. I am hoping condensation.
Thank you.
