forgive the ignorance

Postby metalmulishiaS13 » Sun Aug 17, 2008 10:13 am

I have been looking at the various threads on PCV valves and catch cans. For those of you that haven't completely blocked off your PCV and you have the cheap ebay catch can. Do you just route the PCV back to manifold vacuum?

sorry for the stupid question, I tried finding pictures of where that hose would go, but some of the older posts the pictures wont show up now.

Are you running a catch can with a breather on it too? If so, that installation is incorrect. You are pulling unmetered air in through the breather through the motor and into your intake.

both valve covers route to a catch can and the can routes to the intake pipe.

i ran my 26 covers into a greddy catch can then to a 80deg fittign in my dump pipe to scavenge the crankcase pressure when the dump is open, when the ext dump is open is usually when im beating on it so i figured that where the vacume would b ness
