This says it requires a smaller PVC valve, or elimination of it all-together? What do they mean by this? Also, what is a PVC Valve? And how do I eliminate it or make it smaller?

 

Anyone? =(

 

well dont they sell it. it says 12 bucks for it and 299 for the cover. just get it if it is needed.

 

and the pvc valve is for letting air thru and no oil. it is like a check valve. but you dont realy need it. i got a catch can on mine so the oil that blows by dont go back into my intake manifold. keeps it nice and cleen

 

The $12 is for the shipping cost. So, if I got an Oil Catch can, I could just install it with the valve cover?

 

o opps ok well you can use it as it is from the factory or get rid of it all togeather or just put a cc there like i did. but still does it come with the pvc or no. if not the 8 pvc wont work with the 7 valve cover

 

not that it matters, since 90% of the population says the same thing, but it is a PCV VALVE not PVC. PCV = positive crankcase ventilation.

 

For normal driving I'd want a PCV valve. It might make the intake manifold dirtier but the engine will stay cleaner. For high speed track driving the engine will start to pump a lot of oil out through the PCV valve, I've heard as much as a quart an hour. So then a catch can makes sense. Also, without a PCV valve you become a polluter.

 

I heard that the EVO 7 cover doesn't really fit well with the 8's Some had problems with oil leaks not sure why though because it looks the same except for the raised "Evolution" name.
