Really bad exhaust smell at start up
Ok every1 there is a bad smell right when I start up my car. Smells like somethings burning. The smoke is a blue color but a few seconds after start up it doesn't smell or smoke. Is this something to worry about?

Re: Really bad exhaust smell at start up
If it only does it after sitting for a while like overnight it is probably just leaking valve guide seals. This is very common on a lot of GM heads. If that's what it is, I wouldn't worry about it much as long as it stops smoking after a few seconds. It's more embarrasing than anything.
