I5 07
for some reason i noticed this. Then started looking into. i read that its something to do with the pvc. which h3 is on the valve cover. so i took a air hose and blew air down the driver side because i read that is what gets clogged and it was really bad. I notice the smoke is still coming even after trying to fix. any idea what else it could be? could it have gotten clogged again?

 

The positive crankcase ventilation (PCV) is a simple system that introduces filtered fresh air into the crankcase. The PCV uses the engine's vacuum to pull air through the crankcase and reintroduce it back into the intake manifold.

 

do you know why i would still be getting smoke

 

How does fresh air get into the crankcase? When you turn off the engine?

 

 

Valve cover inlet/outlet/intake ports needs to be cleared for the engine to breathe properly.

 

dead engine. Lots of burnt gases. Look at the exhaust pipe, there will be a lot of soot.

 

Oh, I've read here on the forums that the pass side port is like a backup to the driver side port. Maybe the pass side acts as a backup only when the driver side is not functioning. Thanks.

 

You need both, pass side=fresh air intake & drivers side=intake manifold vacuum.
Watch this:

 

installed new valve cover. Still having the issue…. any ideas?
