Those with Husky or similar catch can read this
Just bought a husky mini filter/separator from home depot for a better catch can mod than I have now. This one has a small drain valve at the bottom that you can turn to let the oil out. Before installing it, I sucked on the inlet with my finger over the outlet (and vice versa) to create a vacuum and to my surprise the little valve at the bottom pulls air in even while closed. I took that valve apart and found a one way check valve that when the bowl has pressure against it, seals. But with a vacuum in the bowl that check valve opens and lets air in. What this means to anyone who has this on their car as a catch can is that basically you have a direct vacuum leak. An easy fix would be a short section of hose with a screw or plug in it on that drain fitting, but thought I would bring this to everyones attention.

I just installed a husky mini filter/seperator last night on my car and noticed my valve didnt even work! I put water in it and it leaked whether i had it open or closed! I was pissed, so I just took some liquid nails glue and sealed the bottom. Glad I tested it before I installed it lol...

Mine doesnt leak at all either. I havent put a ton of miles on it, but I have stuck my finger under it and even put some oil in it to see if air bubbles were leaking in. So far so good for me.

been running mine for about a year too w/o any problems. well, recently it stopped catching oil because the filter was clogged. so i just removed it and it works great now. which size are you using? the small one or the big one? i'm using the small one.

Funny you should post this. I discovered the very same thing this evening at the track. The idle was slightly erratic and I held my finger up the bottom and felt suction but no fluid was leaking. I ended up putting a vacuum cap on it until I can find a more suitable catch can. Oh well... there went $11. Chalk it up to being a cheap skate!

Ripper.... This is the small one. I think when using them for a catch can you should take out that brass filter right from the start to prevent it from plugging up like yours did.

PCV system does not operate at high vacuum so
it may not be a big problem. One end is before
the TB blade and the PCV valve chokes flow to the
manifold side.
But good thing to check anyway.
