Show Me Your Oil Breather Catch Tanks

[JCR]

I just installed K&N watershields, and am now contemplating what to do with the oil breather tube. Anyone have some pics of their (non soda bottle) setup? The catch tank below looks pretty compact and decent (once the decal is removed). I'm not thrilled about drilling holes to mount it though.

Also, I've heard that PMO sells a filter to attach directly to the filler neck opening, eliminating the hose. Any pics or comments on this setup for street use? I haven't been able to find any examples pictured.
If anyone knows a brand/model/part number for a small filter that would fit at the neck, would be a big help.

TIA!

Use a catch can. It separates oil and vapor better than an air filter. However, the direct filter on the oil filler neck does a better job of lubricating the engine compartment.

If you're environmentally conscious, I suggest plumbing the catch can vapors into the air intake filters (K&Ns).

This is the setup on the Bruce Jennings 911-S. It's a 356 window washer tank. They used these on the 911-R's. It's not the best there is but it is period correct I suppose.
I like the setup you show in the photo. It has a way to dump the contents. I've seen similar setups on track motorcycles where there is no breather blow by allowed.
One of my buddies makes them for old BMW's racers. He uses an aluminum tube with steel wool in it. The breather take off on a BMW engine is on the bottom left side (sitting on the bike). The tube is connected to the catch tank and there is a screw cap for emptying it similar to an oil drain plug.

Good luck,

Cheap Jegs chevy valve cover breather. Sandblasted and painted black. Works great, no mess.

Tom is somewhat correct:

"This is the setup on the Bruce Jennings 911-S. It's a 356 window washer tank. They used these on the 911-R's."

It's a washer bottle from a 1966/1967 911. Part number 901.628.720.22
Readily available from Stoddards. Look up the thread from Bob Tilton for the bracket to match the 911-R mount for this bottle.

I've ran a breather hose to a similar tank with a continuing line to the back of the stock air cleaner.

Translucent or clear is nice - to see if it is collecting.

Asleep at the switch again. I was dreaming about "The Last" Carrera Speedster at G&W when I wrote that.
If "ifs and buts were candy and nuts we'd all have a Merry Christmas".

I know what I want.

Best,

Just to add, the way Tom has shown the can is how the factory did it when you ordered the Sport Kit with the car. It also included a rubber 356 fuse box strap and two metal brackets to mount the can. The parts were delivered loose with the car for the owner to install.

Interesting on the factory 'catch can'. When Stoddard built my 2.5 in the 70's they simply piped the breather hose thru the side wall into the wheel well ..... yeah, I know, not the correct way to do it. But that's what they did and it seems to have worked with no problems for +25 years now.

Curt...did they put a filter or screen on the hose?....John
