About it being a serious problem I really dont think it could be possible I mean I guess anything is possible but the motor only has about 30k since rebuild. I sure hope its nothing I have to take it out for. I was told leaky valve cover gaskets and they replaced them for free since it was part of the tune up I had done by them about two months ago. I will try the exhaust checks as soon as I get it back from the shop. If I find anything I will let you guys know. Thanks for all the inputs. -How hard is it to replace the cable that controls the opening and closing of the defrost vents?
