Occasional smoke/smell coming from valve cover?!?

JAWzN54 · 05-13-2016, 07:26 PM

Ok, so its been happening on and off for a couple weeks now. Sometimes I'll be ok for days at a time and others it seems to happen every time I slow down or stop.

So, I took it to my buddies shop to get it on a lift and we didn't notice anything "leaking" per say but what I did notice was subtle hints of smoke coming from around the valve cover/oil cap.

What is this? How do I fix it? and is it in emergent need of attention?

Thanks

Probably a leaking/cracked vcg/vc. Pull the spark plugs and look for oil, and oil underneath the engine cover

This a costly fix?

Around 300 - 400 to replace the gasket I think

The whole kit from ecs is bout 400 I think, then diy. Be like 1000 at the dealer.

This requires lots of tools and is quite difficult. Not to mention you can break clips and still even then not get a perfect seal on the gasket. Don't attempt the DIY unless you're patient. I got lucky my first time

Ok..well I'll prob get it done by a mechanic being that this car is new to me and I don't want to jack anything up..but this is what I thought it was.

It's a lot of work but not that difficult. Took me about 4 hours the first time to replace the gasket. Later my valve cover had a crack in it so I had to replace the whole thing :valve cover and gasket . Only took me 2 hours the second time.
