OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

Breather Box Kit, Stand Alone, EACH
Breather Box Kit, Stand Alone, EACH


 
Breather Box Kit, Stand Alone, EACH is a vented box with 4 ports to connect breather hoses to various points on your engine. It's purpose is to ventilate "blow by" to the atmosphere after removing the suspended oil droplets, rather than having it pressurize your engine and leak oil.

Mount the box (cast aluminum, with foam in the box to filter out the oil from the blow-by) on your firewall, and there are 3 hoses to run. Most people run one hose to each valve cover, with the 3rd hose to the oil filler tower or fuel pump block off plate.

The best way to do this is to not use the supplied fittings (they leak), but to run your 3/8" NPT Tap into them, and then install brass or steel barbs or -8 flares on with loctite. Now you have a no-leak system! With the box threaded, you can install 90 Degree fitting THEN the barb or -8 fitting, for a really slick deal.

While most guys run a hose to each valve cover, we have found (thanks to Muffler Mike) that the 3/4 valve cover gets REALLY full of oil on hard runs. So use that to your advantage, and don't bother porting the 3/4 side! Run TWO vents from the 1/2 side to the breather box! This removes another opportunity for oil to make it's way into your breather box, THINK.

Make sure the hoses slope DOWNHILL from the box all the way to the engine that way oil can't "pool up" in the hose, which will cause burping and pressure backup into the case. Sloped hoses will return the oil to the sump where it belongs!

If your engine leaks after this is installed, your engine has something mechanically wrong with it, usually bad rings or a piston.
