Stupid PCV question
Ok this is going to be a rely dumb question. I know the difference between a PCV system and valve cover breathers. The question is, can i get away with having valve breathers on each valve cover, instead of a pcv system?

Lots of people have tried that (including me). Smokey Yunick tried some variations too with limited sucess. His designs tied the valve covers together and used a remote puke tank with breathers but that design isn't as "clean" looking as the stock PCV setup (that actualy does work). The blow-by gasses can force out oil mist vapors out the breathers and that can make a mess. It just isn't worth the effort IMHO. Give it a try if you want to but be sure to hold on to the stock valve covers and breather parts so you can switch back after your experiment.

I think that all you'll do is fill your air filter casing with a oil sludge. The oil vapor needs to be sucked back into the engine combustion chamber to be burned. I'm kinda confused as to why you'd want to do this? I mean what's the benefit?

You can have 'em both, 'ya know? I'm putting a shiney looking breather on one side (driver) and a matching shiney looking PCV on the other.

thanks, i am in the middle of my engine rebuild, unfortunately i have been delayed, someone hit and run me in some POS Aztec, and my back is messed up, cant get off the couch. It sucks. so i am taking this time to plan on what i need to do next, and the subject of the pcv crossed my mind. Hopefully i will have everything planned out, and studied up, so my build goes quick.
