my catch can setup right or wrong?
this is an 88 tII motor that i have swapped in my base model 87. The car has absolutely no emissions including the charcoal canister. I just wanted to know if there was a better way to have my catch can. I used a kobalt air water seperator from lowes and drilled and tapped the top to put a cheap parts store filter on it. There is an in and out line on it and i have the lines going from the middle iron to the in port on the seperator, from there coming out of the out port going into the oil filler nipple. I was thinking of running a line from the oil filler neck to a vacuum source on the intake manifold through a one way check valve and capping off the out port of the seperator all together. Any input is welcome.

I don't understand why you used an air/water separator. Easiest way to setup a catch can is to run one port from the crank case (iron/filler neck) to the catch can and put a filter on the other port on the catch can itself for a vent. This will relieve crankcase pressure without allowing contaminants to enter it and the oil/water mixture will fill up the can...
And yes you could run the PCV setup if you wanted. The catch can is better though from a performance perspective because it doesn't allow the engine to consume excessive oil.

66 impala... I like where you mounted it! And it's setup properly. There's 2 different proper ways to setup. Your way, and KhanArtst's way.

^If you don't do any serious driving through turns you won't have a dirty engine bay. Most drag racers leave the port open for a vent. If you autocross or road/mountain race though you'll have oil literally spill out of that port.
OP: I imagine what the air/water separator does is let the liquid drain into the can while allowing the air to escape back into the crankcase...this is the only valid explanation I have. Still doesn't make sense though since most of the air pressure probably escapes through the vent (filter).
You can leave it like is though, it still gets the job done.

Okay, new to catch cans and turbos all together, but i do know what a catch can does, just not how to install one, if im reading this description right, you would run one line from the iron to the catch can and put the filter on the other port of the catch can and thats it?
