Fi guys howed you fix your PVC system? Well ive about had it with oil shooting out the PVC system.
I put two breather caps on the valve covers and filter for the pvc line.
The filter does its job on preventing oil going to the intake, but the oil consuptioon is too great. I have to empty the catch can in the filter every couple of days and the filter leaks some.
When i went to the track I talk to some guy named Sonny He had a Mid-nine second LT1 Trans am, supercharged and on the juice.
He was telling me what he did to fix this problem.
He took the egr air pump and hook the vacuum to the valve cover breather and the exhaust out to the atmosphere.
he said this completly fixes the proble and doesnt worry about it any more.
im going to try this this week end.
has anyone else done this?
or does anything else work?

I've got a link to a company from one of the boards that sells a product which is specifically designed for this problem. It's solved this issue for a number of people. I'll e-mail it to you.
OBTW: Are you satisfied with the boost controller? I haven't heard anything FROM you... If you're pickin' up what I'm layin' down...

Re: Fi guys howed you fix your PVC system? SS, Would you mind e-mailing that link my way,too? I am also looking for a better way to stop the oil injestion on my 2000 SS.

Re: Fi guys howed you fix your PVC system? The inital way the incon setup had it was a one way check valve inbetween the normal PCV output and the inlet to the manifold. That worked very well, never had any problems.
I've since gone to a single -10 breather line.
so no PCV problems or even system for me <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
The AIR pump trick is the old vacuum pump setup. using the pump instead of the engine itself to pull a vacuum on the crankcase.

and tell us some nore info on the -10 breather line.
Id like to avoid using the vacuum pump cause of weight.

Re: Fi guys howed you fix your PVC system? the vaccum pump weighs like one pound
i've been running my airpump as my crankcase evacuation for a long time now, my valvecovers are sealed off, so is my throttlebody, i have one small breather on my valvecover and i pull vaccum from the ls6 intake valley port, through my stock pcv valve, into the air pump and dump to atmosphere.. no more oil in the intake.
i have it hoooked to a throttle position switch on the throttlebody, but am working to get it hooked up to one of matt's window switches.
it is very cheap and easy to do, its crazy why more people dont do it, ive posted about it a few times, but little to no response.

Re: Fi guys howed you fix your PVC system? Hey mightymouse, can you give me more details on how you hook this up, and show pics if you got them.
Gonna attempt it tomorrow on my day off.

Re: Fi guys howed you fix your PVC system? George C had a setup on his car to where there was a tube running off the breather valve that welded into the collector of the header...
I'm having issues with my PCV system right now...the inside of my intake is shiney, which its never been before, and it looks to be pretty glossy in there, I'm going to see if its actually oil tomorrow...
What is the easiest way to get rid of this problem? I will be adding a D-1SC in the spring time, so will what I do now be effected by putting a D-1sc on, will I have to change the setup? Does anyone have any pics of what they have done?

Re: Fi guys howed you fix your PVC system? twist the two power wires together (orange) and then you have a ground wire.
run a power wire to where you want the pump mounted, stock locationworks great, i moved mine to the passenger side for the turbo.
hook the pump up via 30amp auto relay and connect the ground to turn the relay on with a momentary switch, mine is hooked to the throttle position so it cuts on when i tap the gas.
after it runs connect the side that sucks to the crankcase, and the end that blows, route it to somewhere that can get a little oil on it. dont forget to put a vent somewhere that will let fresh air in to the crankcase, but on the opposide side of where the pump hooks up so you have to draw it through the engine, not just across the top of a valvecover.

ive moved to the passenger side since then, same thing though.. i used all stock airpump tubing.
i have a video of me turning the pump on and off with the throttle.....somewhere.
thats pretty much it, it will be better once i get the window switch to run it correctly.

Re: Fi guys howed you fix your PVC system? Thanks for the post Smokinhawk I am using a metco breather and is sucks! oil is flying up the tube and out the filter then drops on the headers and smoke every where I have to roll the window down to breath. What are the FI guys doing about this and why aren't the PCV taking care of it? HELP HELP HELP

Re: Fi guys howed you fix your PVC system? I had the same problem with my breather dripping oil on the header and smoking like a ****** <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" />
I added two one way valves on the hose coming from the intake (replaced the stock pcv which is only really good for vacuum) and the hose coming from the TB into the valve cover. This has seemed to fix the problem. If you take the stock pcv and blow on it you will see that pressure on the inlet will still push past the ball.

Re: Fi guys howed you fix your PVC system? Oil in the intake is not a problem with my Incon setup. But I need to get air out of the crankcase so what if I take of the rear tube and PCV off and put a breather or will it leak oil. B/C I know there is a sheild in the cover to block oil from this hole. It would fix the problem for less than $10.00.
Re: Fi guys howed you fix your PVC system? the pcv system has vaccum connected to it to suck out all of the combustion gas that gets into the crankcase.. if just vented your oil will not last as long, but 3kmiles i'd say is still ok.
the stock oil sheilds stop the liquid oil but not the oil mist, which is what gets out onto your headers AND the mist is what oils the intake.

The evac pump sound good, but are you guys just using it as a patch for a motor with excessive blowby ?
Can someone explain why the stock PCV system now fails for you from it's original design?

Re: Fi guys howed you fix your PVC system? mightymouse can I just put a small breather on the tube or tubes on the passenger side and be good and is anyone useing Metco breathers without this problem?
Re: Fi guys howed you fix your PVC system? a breather will function fine, but the way to keep the oil out of the intake is to sever the connection.. if you want to run breathers then remove the pcv system alltogether.
if you have oil comming through the filter then you need to get a better filter, one with internal oil shields and such.
