Nissan 370Z Forum - View Single Post - DIY: Dual Catch Cans with Air/Oil Separators... On the CHEAP!

I'm starting to wonder if my cheap Godspeed oil catch cans is having difficulty handling boost since the lines feed into the upper intake manifold. It's already not sealed that well out of the box, and the RTV and epoxy is probably not going to help much when it starts building up pressure. The JEGS air/oil separator apparently is rated up to 150 PSI. That's probably an important requirement... [sigh]

[EDIT] Nevermind on the JEGS because the poly carbonate housing will crack over time. I guess it's time to invest in a higher quality all aluminum catch can that can handle boost. Here's what I'm looking at: Mishimoto MMBCC-MSTWO-BK. I plan to use brass fittings with Permetex Aviation Sealer for the threads.
