ive got a sbc blowing oil out the breathers at high rev.............why???????????any help would be great!!!!

whats hi ? ... buy a better set of breathers. baffles .stand off towers help keep oil in the covers. in a engine there is volume on top of the piston coming in. there is volume under the pistons the more Rpm + pumping speed = blow by can happen

I concur w/Pat. If it's a brand new engine you may have pressure differential until rings seat. If it's an old tired engine, may have blow-by from tired rings.. try breather on one side and PCV with vacuum to intake manifold on the other side.

I'd make sure it has baffles in the valve covers as well.

i did say that he neededs baffles . but if rings are on there way out or not seating not to sure about a pcv valve it may suck oil into fuel air mix and thats not good . race stuff better to see it blow out the breather then suck it in and try to burn it

I remember years back with a 327 block I used to run it had the blow by tube on it, I replaced it with a rubber plug, when I tacked it up to 5-5500 rpm it would blow the plug out, even with breathers
