Coolest Oil Catch Can

Chuck33079 · 06-12-2013, 12:41 PM

I'd have to look. The couple of FI guys running catch cans that I've seen in person opted to use two cans. Plus, there's a easy place to put one on either side without running hose all over the engine bay. It just looks sloppy, and I'm OCD enough about the engine bay that it would really irk me.

The ones I've seen running 2 are just each valve cover. That can go to one can. I haven't see a crank vent can yet.

I'll try to find the diagram. I remember a crank vent being mentioned, but I barely remember what I had for breakfast, much less a picture I saw months ago.

Run one can and T tape the lines in a orderly fashion. IMO If you mount the can the the middle of the front section of the motor the lines will be perfect equal length. And the color is is important. Like black.

I'd want to use clear hose for the outlets at the very least.

You mean this? I just find it weird that the crank vents are so close to the valve vents and they're both on the valve cover. If the hoses on the inlet tube are in fact the crank vents then they must just run through the valve train down into the block some how.

Although now that I think about that, that's impossible. The crank vents always get the PCV, not the valve cover. So the inlet tube hoses are the valve vents and the PCV vented hoses are the crank vents.

I don't think I'd run it like this though. I'd want the cranks by themselves and the valves by themselves.

That looks like it. Good find.

As I said I ordered a Mishimoto catch can. If you do also they are on back ordered till mid July.

Covered this in a different thread, but the fat connection (rear most) on the valve (cam) cover that connects to the intake pipes is an inlet, the skinny (forward) is the outlet, the system depends on manifold vacuum to evacuate the crankcase and heads.

Confirmed this via vacuum testing the engine while running and monitoring the MAF voltages... The manifold vacuum draws air from the intake pipes, through the heads and crankcase and out the forward nipples.

Cans are only needed after the air exits the forward nipples.

And on topic, that catch can is beautiful and completely over-engineered/bling item. No way in hell I'd pay $500.

Hey Andrew, we should go into business making catch cans.

I just sucked and blew. Flow confirmed

Hey don't forget me now! After a race or street time pull your manifold tubes. I wanna see how moist they get if any.

I checked after a short trip around the neighborhood and found oil in the inlet to the can, nothing on the outlet.

I'll do another check after some actual miles and the dyno day I have coming up and report back.

What affect does it have when you "Y" the inlet and outlet tubing? Or should you run two catch cans? the only can I have seen that has 2 inlets and 2 outlets is the ARC can.

I am worried that the joining of the two intakes will effect how the throttlebody on each side works by changing the return pressure or am I just smoking crack?

I have zero issue, just dynoed too with no tune and running a little rich. Also have about 27mpg!

The valve covers come into the AOS bottom, there is internal baffling, then the top Y's off going to each port on the mani. The bottom is the drain hose. Again zero issues and collects a good amount every 1000 miles when I drain. The return hoses are also bone Fing dry

I also cut my can in half and join it with a coupling so when I really want to clean it, I just pull it apart.
