OIL-PCV-BREATHERS?What works? It would be nice to have this as a sticky. As it is the on thing I still can't get fixed.
What is everones setup for PCV, breathers, catch cans,ect...
To solve the oil everywhere in the engine bay or everywhere in the intake. I have seen some people block of the port in the TB and some people put K&N breathers on each side of the valve covers.
I would bet everone has had some level of oil/blow by problems.
I have tryed
checkvalves in the PCV
Breather tank--not bad--
K&N breathers on each side
EVAC tube to the exhaust--not bad but alot of smoke
LS6 motor with the pcv in under the intake and breathers and breather tank
What will work EVAC pump to pull vac out of the motor?

WELL this is what I did BUT I got an LT1. I pluged the side of the throtel body. Then I placed a T on top of the Valve cover where the vent line was (that connected to the TB). On one side of the T i placed a check valve that only lets air INTO the line and I placed a small filter (K&N) on the other side of the check valve. That lets clean air into the block when its needed. ON the other side of the T i ran a Line all the way back to about 2 feet from the end of the exause tip (AFTER my STS turbo)with another check valve that only lets gasses OUT and wont allow the exaust to back into the motor. This is intended to act as a venturie or sorts and pull air out of the motor when the exause Rushes past. SO far It seems to work? At Idol the PCV can get fresh air from one side of the T and at BOOST the Pressure is vented threw the other side of the T to the exaust pipe. all of my lines and fitting are 3/4". Only Oil leak/problem I am having now is my STS return line oil cap. This will soon be resolved as I just got as solid Bullit (sp?) Oil cap which I plan to tap the STS line into. The oil is being pushed threw the 2 piece stock plastic can under boost right now. I hope the new cap will resolve this problem. We will see? AGAIN this is on a LT1.
Overview:
99-02 valve covers
2 TTI breathers, they are 1/2 shielded
-One is in the back of the driver's side valve cover
-One is in the front of the passenger side valve cover
That's it:

they are total seal rings and are file fit. As well as the motor is spanking new and these is one of it's first dozen dyno pulls!
My driver side valve cover port (that goes to the TB) is now a 1/2" tube that goes to my breather tank. and on the driver side I have a K&N only and so far that is where the oil mist is coming from?
I will try some of these ideas.....Please god please keep the ideas coming.....

I will do alot of street driveing and think I would be burning alot of oil! I am also thinking my catch can need a line to return oil to the motor as under realy hard driving the can is full of oil. That is alot of oil in only a few hours.

I got the 1/2 shielded TTi's because my Metco's will mist out the driver's rear one and I see that as a fire hazard.
I got some other stuff at the warehouse that I have not used, basically some othe catchcans, but I ran into problems with space. Ideally I would run a hose from each cover into a catchcan that was vented up top.
If I was where I wanted to be, I might consider running a Moroso evac pump but I'm not ready to try to get that rigged up.

IMHO ProStockJon
I like your setup as it look realy clean and simple but I had a metco breather and oil would mist out and get on the headers!
Now you said you would run 2 lines (one from each cover) and run them to a breather tank? This is what I am going to do. But i would like to run a line back down to my oil pan, or something.
When I said I was getting that much oil in my catch can, that was when it was a stock motor on 12psi. I am sure with my new motor build up it wouldn't do that.

Well I have been playing with breathers for quite a while, even when I had my old 422ci NA setup. I like these shielded breathers because I can position the driver's side rear one so that the oil won't mist out the back of it and coat the firewall. I can position the passenger side front one so that it won't drip oil on the header primaries. I have had both happen with the Metco breathers.
Better but more complicated would be good sized hoses running into dual catchcans or one big can that was vented. If the hoses were braided and were attached to fittings in the covers that would rock but I would need a set of covers to use for that. I was looking at just using some pcv type plugin stuff into the pcv holes that would run to the catchcan(s). I don't think I would try to route my stuff back to the oil pan I am too lazy to even think about that. I don't think I would run them to the headers and try to burn it off since if my exhaust got real blued up that might freak out the team.
