Okay for a while now I have been trying to figure out what to do with my pcv system now that I am in the FI club. I am running an sts kit with their setup currently but it is flawed. If you are familiar with it great if not oh well. Anyway I currently have the line from the passenger side valve cover going to their solenoid which switches that line to atmosphere when is senses 1 psi of crankcase boost. Everytime I go under boost the car spits a good quantity of oil from this line which is my problem. It is going all over under the hood and worrying me about starting a fire. Anyway the crankcase I realize will get a good amount of pressurization around 1 psi maybe more. What I believe is happening that under high rpm the engine oil is pumping the most which as of now is being returned to that stupid sts oil return system (which I will later change to return to the oil pan) but the way I figure it is all that oil is more or less filling the vavle cover with a good amount of oil and the slight pressure in the cranksae is spitting it out of that hose. There is a check valve on the big pcv line coming off the intake so that I am not fully pressurizing the crank case. what I would like to know is what to do now. sts's idea is for emmissions which I care nothing about so I was planning on running a catch can but i have not firgured out how I would do that. Now I am thinking of blocking the line off and running one of those oil cap filter/breathers. Another problem which I am not sure if it is true orf not yet is that if I am fully boosting the crank case the sts scavenger pump doesnt have enough nut to push the oil into the cranks case causeing the chargers to back fill and smoke terrible. It is all really pissing me off, anyway I plan on remounting that oil return pump in the back as close to the chargers as possible while running the oil line back into the oil pan. after that though i still need to know that I am not pressuizing the crank case. Any help would be great right now. wow i wrote alot sorry about taking up so much of your time.

 

no one?

 

The turbo oiling system on the STS is what kept me from buying it. It looks to be marginal at best, with too many points of failure.

I really don't see why someone doesn't come up with a rear mounted oil tank and pump. This would make the setup near bulletproof, and greatly ease installation.

They could patent this system, and license it to STS

The vent line issue is well documented on this site.

The best solution is to run a larger volume vent line, with some oil separation capability. This, as you have already noted, is an issue for emissions inspections...

 

you are not telling me anything new with the sts oil system. It is flawed for ease of install. If you put the pump in the back right next to the turbos (which I am in the process of doing) and run it into the oil pan the kit is near bullet proof. With of course the entire exhuast wrapped. But for now ignor all the bs I wrote I need to find a way to get the pcv line to stop spitting oil. I am not sure what you mean by a line with oil seperating capabilities can you give a better example?

 

Baffled breathers to separate the oil so it doesn't let the oil leave the valve cover.

 

Alright, any idea where I could obtain such pieces?

Is there any one else with an idea of how to handle the situation.
