So when I drive my car in town it smells bad... I really don't think its an exhaust leak. I have no cat.

I've thought for a while that I may have a bad valve stem seal because of smoking on cold start. Could bad valve stem seals allowing oil to be burned and no cat be causing my smell??

I'm not exactly how it all works but hopefully its that simple. I plan on getting a head from Clearwater cylinder head soon.
