I have been trying to figure what my pcv valve isn't working. I noticed that the cork gaskets were pushed out and leaking oil. So I started looking at the pcv and noticed that there was a lot of oil around that area too. I replaced the Crankcase beather filter, pcv, hose and grommet and I still don't have any vaccum when I take the pcv out of the hole. If I take the pcv valve off of the hose I get plenty of vaccum. I don't know if it's the pcv valve or not but I don't think that it is. I was told to look at the check valve on the break booster. I don't know what that has to do with it but I don't know what else it could be. Any idea's?

 

easy check of the pvc is to shake it up and down it should rattle. if it doesn't its cloged they are cheap so check it if doesn't rattle get a new one.

 

I've replaced the pcv valve twice. I have been thinking about everything that has happen since I got the car in april. I remember one day the car was running like it had a cam ( a wild cam ). When I got home I noticed that the pcv was out of it's hole. Once I put it back in the car went back to it's smoothness. Now all I have is blown valve cover gaskets and no vaccum from my pcv valve, unless I take the pcv valve out of the hose.
