High Boost Crankcase Ventilation Setup

[Clutch450]

Ive been searching around for days and still cant seem to find an "end all be all final solution" for stock pcv valve ventilation on high boost.

I do have my pcv valve set up correctly. PCV hooked to intake manifold. Valve cover vent hooked to intake pipe.
My car is currently running 40 psi at WOT on a fp3065.
Each time I do a full boost pull the dipstick pops right out and spews oil.
My rings are good. 165-170 lbs compression accross all 4

The only thing I can think is that the little valve cover vent tube is not nearly big enough for the amount of boost pressure being created.
Ive been thinking about welding bigger -10an fittings onto the side of the valve cover for better ventilation.
But I am unsure on how I would keep oil from flowing out of the big fittings...

Ive seen guys eliminate the pcv valve and put in -10an fittings with lines routed to a catch can, but once again how does their set up not just spew oil into the catch can and overflow it?

I'm just banging my head here trying to figure out a solution so I can finally get my car on the track.

a good catch can and possibly a dual hose vent setup will help according to others. It will also help remove the oil sludge that builds up it the pipes by filtering it out.

The larger fittings and lines will for sure help. The oil stays mostly in the valve cover because of the baffle. I recommend keeping baffles in the valve cover, or else you will fill a catch can every couple of passes. Also take some vice grips and just slightly collapse the tip of the dipstick tube. It will help keep the dipstick in under boost.

clutch, just curious but your mods list..... damn! dude, ## dyno doesnt reflect at all what you could have, right? i mean, youve got like a 650+whp setup going from jsut browing through it quickly. good job bro. im jealous!!!

I run 2-10's off the valve cover, and I was still popping the dipstick on a fairly healthy motor. The biggest issue with this is that the blow by gasses have to come up the oil drain into the head, and out the vents in the valve cover. That's bad because it prevents oil from returning to the pan, and can promote oil starvation.

I'm planning on venting the crankcase from the balance shaft hump.

Thanks!! That dyno pass was made on my gst which is only a 2.0 6 bolt motor on a 60trim at 22 psi. I have yet to dyno my gsx.
Still working out all the kinks, but yes on E85 I'm shooting for ~650whp
