i've noticed that my breather on my valve cover has been covered in oil, its the filter type and i've got ford racing valve covers w/ victor jr heads solid lifters. my buddy said that the lifters splash oil but not enough to coat my breather. a mechanic told me to check the pvc valve but that checks out fine.. i'm lost if any help it would cure my headache...

run a compression test and post results to rule out blowby.did this just start or did it start after installing the racing valve covers w/ victor jr heads solid lifters..below is some good info. on compression testing...

Did you also check the screen under the PCV valve? They have the tendency to get all caked up with junk over the years and that will prevent your PCV from operating properly. My 88 was doing the same thing and changing the screen and PCV helped alot. Didn't completely solve the problem but helped a bunch. I believe that the motor is getting old an dhas some blowby and that hasn't been fixed yet.

did you notice if the underside of the valve covers had the vent baffles removed...sometimes these are removed to allow for rocker arm clearance and will cause the symptoms you talk about.

yes, the vent baffles if removed cause this problem alot of times..and yes there is a screen under the pcv valve that might need cleaning and or replacing. you cannot see it with the motor or intake in the car but you can use a paper clip and bend the end into a L shape and fish the screen out of the pcv hole. after you remove the pcv valve the screen will sit just below where the pcv valve sits....
