Valve Cover Breather Or Evacuation System?

[andrewsg]

Howdy All,

I have a 333 Cubic Inch stroker setup 9.5 to 1 compression ratio ultradyne custom cam, vic jr intake, aed 'eliminator' carb and a small nitrous system (125/250 wet shot).

I currently have a K&N breather on either side of the motor (on the valve covers) and all seems well except oil is leaking out of the breathers because the valve covers are no baffled. I believe if I exchange the covers for baffled ones, I wont have this issue. Am I correct in thinking this?

Second off -- I have access to a Mr. Gasket Crankcase Evacuation system, which puts breathers in the valve covers, with hoses that go to a check valve and the check valve screws into a tube that gets welded at a 45 degee angle into the collector of the header.


I think I'm going to just first swap valve covers and see if that fixes my issue. If it doesnt, then I'm going to go install the crankcase evacuation kit.

Does anyone have experience with what I am speaking of?

Car had a mr gasket evacuation kit on it previously but that is because it was a drag only car. Now its for the street. Should I be groovy if I put baffled valve covers on and just swap the breathers to those covers? Or am I going to cause bigger issues, etc.

Let me know!

Anyone?

A friend of mine uses the evacuation kits on all engines he builds. It does make it look like the engine burns oil. Is installing a PCV not an option?

 

[andrewsg]

My question is -- how would I install a pcv on this setup? the manifold doesnt have a pcv port on it. The carb has a couple vaccum ports in the base plate the big one in back goes to the vaccum tee for the brake booster and gauge. The other ports on the carb base plate are plugged.

I could run a hose from one to whichever etc, but how do I set up the pcv system? How do you have it on your car? Is it a breather setup or a pcv or what.

Thanks Much

Perhaps you could just drill the vaccuum port you need in the intake and hook up the pcv.

I know this sounds silly - but I would rather not drill into a brand new intake -- I'd rather stick with what the motor already has and work from there.. Knowing my luck something ill-fated will occur. Car isn't nicknamed "pandora" for nothing.

there are crankcase pressure kits that don't plumb into the exhaust. i'll see if i can find one.

I am also kinda at the end of the line money wise - I'm trying to use one of the three setups I have right now.

Current Setup: Non Baffled Covers & Two Push In K&N Breather filters, One in each cover.

Option 1: Change Over To Baffled Covers & Keep Push In Covers

Option 2: Change Over to Baffled Covers & Run Mr. Gasket Evac System

Option 3: Keep Non Baffled Covers & Run Mr. Gasket Evac system

Option 4: Something under 15-20$, won't be getting paid for another week and that money has to go to court fees, this weeks went to mortgage and insurances.

i would say get one of these and run the Mr gasket evac set up but this way you will not pull any oil into the exhast so it won't look like you are burning oil.

that part i think would do the best job at removing all the oil I know the caps you are putting on the valve covers are also supposed to do the same. I would definetally baffle the valve covers making it less likely to get oil out of the engine.
