Alright today I noticed that there was smoke coming out of the filter that I have on the valve cover for venting. Not a lot of smoke but there was a little. Dont know what would cause this? Is this normal or should I be worried. Also pulled the dipstick and there was a little smoke coming from the dipstick tube as well???

 

what kinda smoke?

cause the other day i saw the same thing from my motor from the vent as well.. but it was like light smoke. not dark oil burning smoke.

 

same thing here.

 

Maybe just internal condensation burning off. How long did this last for? Mine used to do the same thing when I had the rocker cover vented to the atmosphere.

 

It is normal for a boosted app to have a little bit of blowby. How do you have your pcv setup? If its all vented like mine then you will see a little bit more than if you have your intake pulling a vac with a checkvalve.

 

Oh ok, yeah I have filters on both valve covers, been that way for over a year. Probally been doing it the whole time just never noticed. Thanks.

 

Yup! Its your PVC setup. I had the same problem. I redid my catch can and it stopped. It was a white smoke coming from the valve covers.

 

What kind of set up are you running, any pics?

 

I also was venting to atmosphere

 

No pics right now. But very simple homemade catch can. At first I had both valve covers going to the catch can and then venting to atmosphere. It was smoking. Then I took the filter off the catch can, then ran a hose to the intake. Problem solved. I have not installed the Turbo yet on the avalanche. When I do, that hose will go after the Turbo filter.
