Cusco catch can install diagram

Suspended oil particulate as well as fuel and water vapor can be extracted from the blow-by using a catch can. Normally blow-by is piped back to the intake to be burned off but the catch can with a proper baffle should be able to extract much of this material from the air so the intake has minimal oil exposure and maintains a cleaner condition.

How's that?

Thanks! Yeah I understood the basic concept of it's function, but thanks for both of your input

So what I was getting at is as long as you have one end on the PCV and one end on the intake side (to pull vacuum) their is no wrong way to install this part.

I wonder how many noobs bought the Cusco for the looks and then either connected it wrong and collected nothing, or just left it to gather dust. The product looks nice but poorly packaged, that's all I can say.

Unfortunately, probably many based on the pics I have seen. And in all fairness to NOOBS, you probably can't blame them if you look at all the different configurations people have used to install the Cusco catch can.

Then there's the individual that will occasionaly pop into these types of threads and say that the Cusco catch can is absolutely useless in it's design. The troubling part is, they really seem to know what their talking about and seem to have an expert opinion on the matter.

Needless to say, it's frustrating...

Yeah I'm sure many noobs have it set up wrong. But truthfully this can has some function but it doesn't work as well as a separator that Crawford has, to separate the oil, gas and water (moisture). For the price of the Cusco can its worth it for more people then the Crawford separator.

Yeah for the everyday driver the Cusco is probably fine. If you track your car, then Crawford is more than likely a better solution

I've even heard some say that the catch can is pointless altogether, unless you track your car

I'll be that guy this time. I bought and installed a Cusco catch can about 6 weeks ago. I made sure it was installed correctly, between the actual pcv valve and the intake. The documents with the can actually show it installed incorrectly, that probably should have tipped me off. After over a month of hard driving, the catch can was bone dry, but the clear tubing used with the can was filthy with oil vapor. I think that the lack of baffling combined with a mounting point in the hottest part of the engine bay right above the engine prevents any real accumulation of oil in the can. This past weekend I switched to the more expensive, but better designed, Radium can. It's already starting to show signs of oil accumulation after three days.

Yeah I've seen the post but truly you don't even need a separator unless your pushing out some high HP on the track. I know ill get bashed for this but who cares, I'm sure I drive just as fast and hard as others who track their cars and I do this on EMPTY freeways and on canyons at LATE hours of the night (1:00-2:00am) and I'm sure the Cusco can would work fine. Really all I would want is the oil to stop entering the throttle. Now if I had a turbo or supercharger then I would most definitely run a separator.

I guess mine is pointless then, but I sure as hell can smell the vapors collecting in the can and coming out of the filter on top. I have the D3PE type 2 unit, and I have my hoses connected to the front and the rear with no vacuum in anticipation of my turbo install. Thanks for correcting me on the errors of my ways.

I think your application would be "for off road use" if the fumes are emitted. Not useless. For a DD (which probablywill prove the can useless) I just put a home made baffle inside the can and in the spring when I drive it I will make a point of revving the engine freely whenever possible but I am doubtful there will be much there. It would be cool to have something like the Radium or Crawford which actually does have proven results but that doesn't mean this vehicle will have that much blow-by gas ever if running N/A. Turbo of course is different.

@wbradley Just for clarification looking at your diagram. What is the function of the 16mm to 9mm adaptor for the hose on the passenger side and what was your procedure on steel wool homemade baffle ?

Thanks

The hose supplied by Cusco is 16mm but the diameter of the PCV valve outlet is only 9MM. I improvised a part for this purpose.

I removed the inlet barbs and stuffed in some fluffed up stainless steel wool. Used a screw driver to stuff it in, and hopefully it fills but doesn't overfill the bottle.

Catch cans are meant to release crankcase pressure. They are usually installed on high compression motors(like ours) for motor under high levels of pressure(boosted motors).

High crank pressure can cause engine damage. You don't see or feel any difference in installing one of these. It only benefits the exhaling function of your motor.

[ybotspawn]

Excuse the dumb question, but where did you get the 16 - 9mm adapter? Did yours come with it or did you get it at a store? Thanks
