914World.com _ 914World Garage _ Breather Vent Setup

Posted by: LotusJoe Apr 21 2012, 01:38 PM

I'm looking at different options for the breather setup for my engine. I found several canisters. What have others done?

There is the Berg Breather

Several from EMPI

And one offered by CB Performance

I also have a small oil leak at the pressure relief screw next to the oil cooler. I can't seem to get it tight enough. It's been beat up over the years. It's the big plug with a screw driver slot. I found this replacement for type 1s. Will this fit?

Don't use the EMPI or CB style breather unless you just drive it on the street. For track or AX use, get a catch can with a breather vent otherwise, you'll be cleaning up a nice oil mess.

Tangerine Racing has a solution all worked out for you (http://www.tangerineracing.com/engine.htm#Engine%20Breather%20Can)

...or you can got to Summit, Jegs, etc. and build your own.

...or just use an old Porsche windshield washer bottle.

There was an extended thread, again, on breathers a couple of months ago. I don't want to see this end up as a battle like that one, so do a search to find it.

I agree with the Berg choice for simplicity as well, and Chris at Tangerine has a slick one as well.

Maybe Cap'n, Jake or Chris can chime in on the pressure screw - I just pull one from a shot block when I need one...

You probably don't need to replace the 'screwdriver plug'. Just pull it out completely, get a new crush washer for it and add some Loctite 565. Also check for wear on your piston. There shouldn't be a ton of oil pressure there, so it should be a big leak.

Also, if you are handy with tools, you can buy an aluminum paint spraying cup from a local car paint store and use it as your breather.

Drill 2 holes in either side and mount some nipples that bolt from the inside, seal the through holes with Loctite or high grade black RTV. The bottom hole is already there, just a bit oversized - easily remedied with parts found at most local NAPA's, Autozone's, O'Reilly's, etc. You can make a mount from a large metal clamp and secure it to the firewall, stainless zip ties from HF work too .

Believe it or not, I've seen a few custom units like this - no welding required, and aren't as ugly as they sound, just make sure the sealer you use on the nipples is rated for high heat and petrochems.

Good luck.
