I'd like to re-open the discussion about what type of catch can would be required for use with our cars. Also what features to look for.

I found a rather pricey catch can here - lets use it as a starting point. Is this catch can sufficient? Does it have some feature that makes it useless in a Legacy application...? What should one expect to spend for a basic catch can that will do the job right?

...Discuss.

I don't see why any of these ridiculously expensive tanks would be any better than a little homemade one. Make a little container out of some kind of fairly inert material, fill it with stainless steel wool, and attach inlet and outlet fittings, and optionally a drain valve on the bottom.

Right?

Don't use PVC tubing (the black plastic tubing used for plumbing) for the can. I did, and it wasn't able to withstand the heat/chemicals. I ended up with an interesting piece of modern art!

Very simple, all parts found within 10 feet of each other at Home Depot. About $15.

Hehehe... the picture shows him wrapping the teflon tape the wrong way around the NPT fitting.

That looks pretty cool. I like how it's clear so you can see how it's doing. I had a clear replaceable-element Purolator fuel filter I was gonna use at one point.

I am a little concerned about potential restrictions being added to the PCV system. I wonder if you could find a similar water separator with larger fittings so you could use 1/2" hose barbs without restriction. Those would match the size of the stock hoses.

What in the HELL is Hyundai Performance!?

well its good to know that a water separator supposedly can stand the application. What might happen if one were to use this DIY catch can and, as you say, introduce a restriction to the PCV system?

We're talking about a sealed catch can here, no vents, correct?

That's too funny....wonder if anyone told him

I'm sure that's the same thing someone said when they saw i-club, or nasioc, or clubwrx for the first time.

also how are you supposed to wrap it?

You're supposed to wrap it so when it gets screwed in, the tape actually snugs up a little, and doesn't try to back off.

In that picture, if looking directly at the end with the threads, he should be wrapping it clockwise instead of counterclockwise...
wrapped the way he had it, the tape would tend to unwrap itself as he screws the threads in.

oh okay, I thought there was some ultra secret correct way to do it

You can do it backwards sometimes if you're careful, but it's just easier to do it right.
