Hey guys, want to run a catch can but I have 2 questions I haven't found the answer to by searching so here goes:

You need to search more. That piece is the air-oil separator. It does what the name implies.

You can run a hose from here to there, but expect blowby.

You need to rethink how you're going to route the catch can. There are many writeups and many options to choose.

Problem is the new SS manifold interferes with the mounting points of the air/oil seperator...any suggestions?

since your running a oil catch can, there shouldn't be any blow-by issue from routing the back hose as you have drawn it. Alot of aftermarket manifolds come with a hose to replace the seperator upon installation. I've been running mine like that for 2 years now with no signs of blow-by, and thats without a catch tank also...just a breather filter n the front side of the "t"
