Since you want to keep anything from entering the intake tract, I would install a can between engine grommet and the "T".
Keep can below level of where the two lines enter intake manifold as oil does not like to "run" uphill.

What bone said. I use two cans, one to catch the valve covers and one to catch the CCV. I have DIY's on both on the vca site. I think you can find some pics in my creampuff na build thread there. I catch nothing from the valve covers. Catch mostly from the CCV. The can is mounted on the crossbrace and it's inline with the CCV. Basically, I take the hose from the CCV and run it to the can and run a return hose from the can to the intake. For the valve covers, I use the breather system from A&C Performance but I really don't need it and on my setup it's mostly for looks. I'll post some pics tonight.

My catch can is mounted right dead center on the engine support bar in the front of the engine bay... i would suggest taking your valve covers off and tapping the for a -8 or -6 an fitting... i believe i used -6 an fitting and stainless steel lining for mine. also make sure the can sits believe valve cover level. i tapped both my valve covers... and t'ed them into one line.. to my single catch can..

the catch can i have, has a release valve on the bottom.. which makes draining a piece of cake.. ill tell you what... the shit that comes out of this catch can is disgusting. glad its not in my engine.

plus its also a good way to tell when ur oil is over saturated with fuel when you have a high hp monster... because when you drain... the fuel will come out first... then the oil will come out.. and float on the top of the fuel...

good luck!

I have a crankvent set up from ROE that mounts on the valve cover. So can i plug the 2 openings on the valve covers? then just run one catch for the CCV?

Plug that hole in the top of the block with one of those rubber expansion plugs and run more like a -10 or -12 line off each valve cover to either a properly sized single catch can or two catch cans.

The whole idea of the catch can is to give an avenue for the crank case pressure to exit the engine.

Using a -6 or -8 is not maximizing the benefit of such a modification. The larger the hose ie -10 or -12, the slower the velocity of the exiting crankcase pressure gases and the lower the percentage of oil droplets that will get pushed out into the catch can, therefore less blow-by.

The lower the crankcase pressure, the less strain on the engine.

After I read tonys build on the VCA i got a better Idea. Could I run one catch can off the CVV to the catch can then Tee it back into the 2 intake vaccum ports on the front of the intake so that it the engine can mantain manifold vacuum. Then one one catch can for the Valve covers by teeing them together to another catch can and have that catch can vent?

For NA that will be fine.

For a turbo car, I recommend the way I posted.

How about, capping the PCV, cap the two vacuum tubes (front) on the manifold and tie the valve covers into a single catch can with a single line. IMHO you do not want to tie anything into those two vacuum tubes, that is a direct route for contaminants into the manifold. If anyone tracks their car and does not use a catch can, the manifold runners will look like they are pure oily carbon. I did add a Roe breather on the valve cover to offset the closure of the PCV.

The blow-by is not the whole problem, if you track or autocross the car you will get quite a bit of oil flowing to the can, especially if you have the T&D rockers, they increase the oil flow to the top end. They are not designed that way, it is just a trait that accompanies the T&D's.

I went the capped route once too. If going down this route, definitely cap the valve (I capped it on top of the block) with the intake removed otherwise it's a bitch to get to with the intake installed. One could also plug the line t-ing into the manifold.
