Does Every Body Have This Problem Of Oil Puking Out There Breathers...

Re: Oil Out Breathers
 

I would get rid of those push on breathers and run a hose up to the flame arrestor.

I had the same problem with my Scarab with the push on breathers. I went out and got the push-on breathers with the hose attachment and ran braided line up to the flame arrestor.

That Is What I Was Thinking But I Hate To Give The Motor More Hot Air Would A Puke Thank With A Breather Be Better

Re: Oil Out Breathers
 

Are you also running a pcv valve or just the breathers. The intake can be drilled and taped for a pcv valve under the carb flange if the lifter valley tray is in place and that will solve your problem.

I had this problem with my 502 blower motor because of blowby from the rings/high leakdown. I sealed up the breathers with tubes to a puke tank with a vent on the puke tank and it pushed oil out the seals on motor. I now use extended breather tubes with baffles in them and zero gap rings. Leakdown is less than 10 % where 502 was 25 plus on some cylinders and the taller breather tubes keep what blowby I do get from letting as much oil drip in engine compt,Smitty

What kind of power, you may not need to worry about it. My motors were 550 hp 502's.

Is the oil puking out of both breathers or only the port side? I would try to put both breathers up in front of the covers, that helps this problem. I have no pcv and no tubes to the flame arrestor with no oil puking problems at all.

Wonder if it's the nature of push on's? Mine stay almost 100% clean.

Every once and a while I wipe a little oil off the cover from around the base but I think some oil is very much expected, especially with any amount of power.

Both of mine are towards the rear as you can kind of see in the pic.

Could be.

I now have similar valve covers and breathers as you do and I don't have any oil problems.
