Featured Replies

Did a weber swap now im getting oil all the way up the hose that connects the valve cover to the air filter housing

Is this normal? Any fixes?

Not normal.  You are going to have to post some pictures or a diagram of how you have the PCV system set-up.

well i just swapped it so I really didn't put that much thought into it. I have the passenger side valve cover hooked to the air filter on the weber the driver side has a pod filter on the valve cover and the pcv is just hanging out. Just went down to the parts store and got a new PCV gonna throw that on today

is it driver side valve cover to pcv then pass. side cover to carb?

drivers side goes to a three way fitting with pcv and air cleaner, see in this pic, the air cleaner hose is much smaller diameter. pass side is just straight the air cleaner.

Driver's side house that goes to air cleaner must be smaller diameter than hose from driver's side to pcv

You can put a catch can in the line before the air filter if you have to. Is your motor high milage?

Hard to say when i got it the guy said it had 150 thousand because the head blew on the original engine and he just swapped in a different ea81

the odometer reads 210 thousand so i dunno but its in pretty decent condition except the exhaust

so I got the appropriate pcv setup now but something seems strange

I was kinda under the assumption that clean air goes in passenger side valve cover and gets the blow by gasses and out the drivers side cover to pcv

 

When i disconnect the hoses off the valve covers both are blowing

but shouldnt the passegner side be drawing air in?

it will only work right when it's all hooked up. you are right both sides will blow out when you pull both hoses. put it together and don't worry about it.

Pass head hose goes to air filter. Drivers side goes to pcv. Tee in a small breather.
