Is my PCV setup wrong???
Hi i´m wondering if my PCV is not ok..... ?
here it is.
RED ARROW: I installed both ways hose between the valve covers
BLUE ARROW: K/N filter on the oil gasket
GREEN ARROW: a pcv catch can between the block and the intake whith pcv valve. The air goes one way from the block into at the top of the catch can and from middle og the catch can out into the intake.
THE REASON I AM ASKING is because i´m getting a oil out of the filter on the p.s. valve cover (blue arrow) specially when i´m reving, like when i went at the track it was all oil wet under the hood....
What do you guys think???

Here is a easy way to do it, and you dont need a catch can. I have had mine like this for a few months and there is NO oil in the filter or throttle body. I got lost looking at your pictures, but then again its not hard for me to get lost. Whats up with the tape on the throttle body???

but "no catch can", are you then running a u turn hose from block to intake.
I´m getting oil in catch can, and a lot of it....

Sounds like you've got a ton of blowby... like I did in the 403. I must have run 5 or 6 different configurations trying to control it. Not much more you can do than run the valley pan to a catch can and then to the intake manifold - without a PCV valve - and a filter on the valve cover like you have. I did tie the valve covers togetherwith an 8AN line. I had to reduce the orifice to the breather filter.
Good luck!

All I have is a filter on the pass side where the air hose use to be. Also like Lucky said it looks like you dont even have fresh air going into the crankcase the way you have the hose ran. The stock setup is the hose running from the pass vavle cover to the side of the throttle body to draw fresh air. You will need to tap into the air bridge or the coupler so you can run a fresh air line. Then the catch can will go between the hose on the vavle cover and the hose going to the air bridge/couple. Or just put a filter on it so you dont have to cut into anything.

this is orginal ls6 setup, then i went whith ls2 shortblock, so i have never taken fresh air threw the air bridge.
Air:goes in and out of the "BIG" filter on passenger side.
Air: into the intake from catch can. but i have a pcv valve on the line from crankcase to catch can so there can only come air from crankcase not the other way.
But like i said before the problem is there is too much oil going up threw the filter, and there is a lot of oil going into the can too.
so there must be something not right...
gona try take out the pcv valve.. see what that does...
thanks

On the dyno, you can see oil bubbling up into the filter with the throttle open. When you close the throttle it's all sucked back in immediately. Unfortunately, it's going to be ring seal - or lack there of.

why would you run a filter oil cap with a closed system?
I could understand if you are running boost but otherwise with the pvc system in place what is the point of a oil breather cap other than to cause a mess?

Now that its vented, I dont have those issues.
And on my decel, there is still vapor coming out. never a suction effect...who knows. If its rings, its rings. I dont even care anymore. After a while you just get over fighting it
