hi bcredliner, Thank you. i want to say it odorless. I have stuck my nose into the engine bay to see if its burning oil and not much smell like burnt oil. This morning, after i parked its smoked, then went away, then 2minutes later, smoke again.. kind of like. oil is dripping onto something and burning. this also happens dle at red lights. It's only white smoke not thick. would the coolant be leaking elsewhere causing the white smoke besides from the expansion tank area?
No i have not had a chance to bring to indy to find out the source. Would you recommend things like liquimoly temporary? i was reading other post for their valve seals, but seems like their time of smoking is different.
thanks again
