pvc blowby

[Danny4656]

Hi every one
I installed Edelbrocks classic valve covers on my small block 350.
I had them milled so I could install A breather on drivers side and a pvc valve on the passengers side.I did not have baffles welded inside valve covers.I get no blowby on the airbreather side,but im sure that im losing alot of oil up through the pvc valve and in though the carb then burning it up.I am useing 3 quarts of oil for 300 miles No smoke,no leaks,new engine,plenty of compression.
I was wondering if anyone here knew of a easyer way to deal with the blowby other then welding a baffle in the the valve cover?Any one else ran into this problem?

WOW !! a quart every 100 miles is a lot ! Too much for just a PVC valve I would think...

Are you positive you don't have other problems? I've never run a PVC valve without a baffle. The only PVC related problem I had resulted in blow-by out the breather side that was from a wrong sized PVC, I was told.

Coincidently, THOSE were Edelbrock Elite valve covers...

Thank you for your reply. Im pretty sure its going out threw the pvc valve,Ive got no oil leaks as far as I can tell.I think im going to have to have a baffle welded on the inside of the valve cover and see if that helps.
I removed the pvc hose to the carb edelbrock 600 cfm, and there was some oil on the lip of the intake.It just seems kind of alot of oil thats all.

Had the same problem with a set of stock valve covers off a 283. Put in a long block 350, used the old valve covers and sucked oil like a demon, smoked like a train.

Replaced the valve covers with newer stock ones with a baffle and everything settled right out.

Reckon the baffles are pretty important.

The pcv valve will suck that much oil without baffles, you have to have a baffle or it will not stop.
