What is everyone doing for PCV setups on 300+ shots?


I have a 383 with a 300 shot and I'm hunting down a nasty rear oil leak that I assume to be a pushed rear main from crankcase pressure.


My current setup is a ls6 valley to catch can to intake (fast 102)
Throttle body is capped

Valve covers run together then T to a large k&n breather.

The valve covers are those aftermarket crinkle painted ones- I don't remember the brand.


Any feedback / suggestions?

I had a catch can as well and it would not relieve the pressure properly. I am just venting to atmosphere through a large filter on a fitting tapped into the oil fill cap. All other vents capped. 200 shot here and daily driver. I know mighty mouse has a decent catch can.

my car leaks like a pig from the rear main on a 200 shot. I had it vented to atmoshpere before the spray but couldnt handle the crank case fumes in the cabin, so i switched back to stock ls1 crank venting.

But now that im on a 200, its not liking it at all. Motor is coming out soon to get sealed up, but i gotta figure something else out before it goes back in.

After talking to some people, I'm going to do a -10 line from each valve cover to a large, dual entry, vented catch can.

Hopefully this is good enough-- if not, it's getting a gz vacuum pump setup I guess.

Is this a street car? Do you get a lot of crank case fumes in the cabin?

I'm trying to avoid showing up to work smelling like an engine lol

Street car in the essence that it gets raced on the street.


It only gets driven to meets or events.

I run a breather on the oil fill, and a small breather on the drivers side small nipple. I have the hose that runs off the passenger side just vented. No problem as of yet. I daily mine also.
