I've been happy with the MM can. Amazing how much crap gets trapped that used to go to the motor

it is fine to have confidence in your product but it is not 'independent third party results' in any stretch of the imagination (as it is made to appear)... so at a minimum take it with a grain of salt.

i am too busy filling orders to pull tricks like that, but I am designing a test rig that will be able to test anyones can in several key areas of performance, and do it all on video. open to suggestions!

Elite has a "clean-air oil separator".. does that mean that the catch can won't separate oil from air?
Pressurized air from the block can go 'backward' through the 'clean air intake' line, when at full throttle. So this piece is a separator (and maybe a check valve) for when dirty air is going back into the intake. The ones I've seen go on the oil-fill port and the line goes to the throttle body air fitting.

I have the Mike Norris one as well. It's a solid piece. I'm stock and don't plan on anything more than heads, cam, and possibly a 383 stroker. If you are planning on FI, the MM or RX is probably a better alternative.

What is the size of the bolt that attaches the catch can to the head? Thanks!

How hard is it to see what will thread into a threaded hole on the head?? This is a THREE YEAR old thread, like the other one you posted in. MIGHT get a reply, but don't hold your breath.

This has probably been covered before but if i have an ls6 valley on my fbody, would i need the f-body can from MM or the c5 corvette can? I'm guessing I would just need to change the routing on the fbody can?

Mighty Mouse setup:

-Won't have increased crank case pressure and blow off my rear main seal
-Doesn't smell horrible once I pull it into my garage causing me to have to leave my garage door open for hours
-Proper PCV functionality
-Doesn't look like home made **** under the engine bay
-You can keep ls1 valley cover rather than having to swap it for an ls6

Mighty Mouse was the way to go on my street car setup. I scrapped the whole DIY idea.

I think the MM has a check valve that prevents vapor from getting sucked back into the engine.

Because people who don't know how it all works will pay too much for it. Most of the expensive setups are actually completely worthless once you see the internals.
