Catch can for valve cover? Need opinion on size
 

I'm adding 2 additional ports to relieve pressure off the front of the valve cover. Im trying to get the moroso oil catch can but it comes in either a -12 or a 3/8npt. I want to use that to add 2 additional ports to the front of the valve cover. Which one would be a good size for that? The -12 is somewhat big for it but i guess it could work, how about the 3/8npt? Too small?

Or i can get the summit catch can which is a -6 but it is only a single inlet, will i be able to add another fitting into it? If so how, cuz its plastic.

What you guys suggest? -12 or 3/8npt?

Don't know if it will work or not either, but I just got some -12 AN 90 degree fittings to do a catchcan off the valvecover. I plan on having it welded up soon.

is -12 too big for it? There wont be a problem with going -12 would it? And the only way is to weld it onto the valve cover am i right?

It looks like they'll fit. they will be very close to the mani (full race) but should be ok, I'll definitely have to wrap them with some thermal wrapping (foil looking stuff, not stuff for downpipe)

check out this thread, this is how i'm gonna doit except my catchcan will be on the drivers side near the timing belt mount area.

I am going the weld route.

im not worried about that because im using the lovefab mini-me manifold and theres plenty of room on the top. just wondering if its bad using such 2 big fittings for the valve cover.

That is fine, that is the size that I went with (-12). You can also do this:

Get two (2) -10AN male weld on bungs. Then get the catch can that has two (2) 3/8th NPT ports on it. You can then get two (2) 3/8th NPT to -10AN fittings. Now you have a -10AN valve cover lines.

Just another thought. Actually works real well with the Greddy oil can (the large 15mm one).
