How about running the top fitting of the Peterson to the intake. You get the advantage of two levels of separation and keep the suction ability?

Jockey, what you and Jeff basically say the same thing. He's pulling from the exhaust and you're suggesting the way I'd set it up on TIC's TA car (I did a lot of guinea pig work on it). I also had 'cold' flow on the last can to help vapor condense.
It was amazing how much crap ethanol we were pulling out of the oil. Stuff that'll poison a catalytic converter...for any of you running one. -Micah 3MI Racing Last edited by Homemade WRX; 10-15-2013 at 05:11 PM. |

Went on the vibrant sight and searched google but am having a hard time finding a crankcase exhaust check valve. Im thinking about running my heads vents to the exhaust. Much like the way Sinister Redlines set his up.
Any links, I know Im a rAtard. Thanks for any input. Ian, |

Look for exhaust venturi. It isn't a check valve, unless you guys are talking about something else...

I used a moroso check valve breifly but when it is hooked up to a Pertson, you don't need a check valve bc any BP that may happen will vent through the Peterson filter.
If you use a check valve and your exhaust builds BP and the valve closes, you could have serious issues since your CC will essentially be capped (if using a one can system). |

Scavenging from the exhaust seems to be better since any oil that is pulled will not go into the engine but is there really enough vacuum from that? It says 3" of suction I assume that is inhg which is about 1.4 psi of suction. Of course that does not take into account the loss due to hose length etc.

I ran out of time so I did not pull the down pipe off but I have to assume I'm still having a turbo issue since my oil consuming at these levels started after the turbo was installed. Today I saw black smoke when going in boost, 15-20 psi. I have my AOS vented to atmosphere with a long hose that dumps below the car. I am assuming this is not allowing sufficient breathing for the crank case and therefore oil is pushing through the turbo. I'm going to pick up the Peterson can and put that between the AOS and intake like Homemade WRX suggests. I may try crystals' setup by scavenging from the downpipe if I notice the turbo is sucking oil out of the crank case still. |

You have to have some other mechanical problem. I was pushing 600+ HP with one catch can and the PCV valve, I would get little to no blow by at 31psi.

I'm still inclined to think the turbo is the issue. I never lost this much oil before I installed the turbo back in June.

Which Peterson can are you on? What is VTA?..it's early and I'm drawing a blank. |

Precision says if there is positive pressure in the crank case then it will push oil through seals. When I was on the dyno a few weeks ago I got smoke with connections to the intake with heads directly connected to the intake and my crank case through the AOS to the intake. This to me would mean I had negative crank case pressure but the intake was sucking oil out of the heads. I checked the hose from the heads to the intake and there was definitely oil. Then I saw your recommendation that the heads need to go to a can an not direct to intake since it sloshes. So as of today I have the heads and crank case plumbed to AOS with top going to intake. I'm thinking I want to add the Peterson soon to help keep oil out of the intake but I will check my turbo this weekend to see if I have an oil film at the exit since my headers looked pretty clean. Thanks guys for the input. |

They recommended that I use the crawford separator plumbed into the intake pre turbo for a vacuum source on my comp 6065 turbo build. |

Are they pulling atmosphere through the crankcase or did they seal the crankcase, except for the veturi?

I dont know. I can ask. Wouldnt the heat of the engine running at temp drive out most moisture? Honestly i assumed they saw more because they dont drive it all the time.

Checked the turbo and definitely has oil on the turbine housing behind the wheel. Oil must be getting pushed out. It might be time to get the Peterson between my AOS and intake.

So when u say if the crankcase has no vacuum oil will push past the seals. Do you mean oil will go in the exhaust housing or the cold side? As in it will blow out the exhaust or into the intercooler?

The reason I ask is im already VTA but I'm still seeing oil in my intake manifold.
My engine is making 500hp atw @ 30psi. Was only retuned recently and got a leakdown test done, all good. Got a Crawford AOS hooked up but ended up with to much oil in the intake. I pulled all the ic piping off from turbo to tb and cleaned everything including the cooler core with petrol. Then took the intake manifold off and cleaned that out too. I figured I'd clean it all once and for all since I was never gonna get oil in there again cause I was going VTA. Anyway I pulled the manifold off last week and it's got a decent amount of oil in there. The intake pipe before the turbo is clean though. I just assumed my turbo was stuffed since it's blowing oil. But after reading your post about what precision turbo said, my turbo might be ok if I get a better AOS setup? Basically that return hose on top of the Crawford aos. I get oil blowing into my intake manifold if I hook up that hose or not. |

Blue_diamond it sounds like you are having the same issue I am having. Precision has a PDF that they sent me with Instructions of all the do's and don't's of installing their turbo. It discusses the need for good ventilation whether you do vta or not.
If you do not pull air from your intake or exhaust then you need to have large enough hoses and filter for the crank case and heads to breath. Otherwise pressure will build in the crank case and the oil will have trouble draining and push out of the turbo. I think in my case the really long hose from the AOS to below my car may have been restricting breathing causing this form of oil loss. If you do connect to intake you have to try to eliminate the sucking in of oil. Since you are creating a vacuum in the crank case there shouldn't be an issue with oil return from the turbo. This is where I am at now. The 6466 probably sucks so hard that it pulls oil straight through the AOS. This is why I want to put a second baffle system in to try to minimize the amount of oil that does get sucked in. It is bound to happen but I think it is better than being pushed out the turbo. If I am getting to much oil sucked out then I may either do scavenge from exhaust since the suction from that should be much less than from the intake. As long as there is negative pressure in the crank case it should be good. Or I will do two vta cans with big ass filters. I have pics of my turbo from last night ill post. I also felt oil on the Intake side. It was a small amount but I think that is from the AOS being sucked in. One more side note. I finally cleaned my air filter while I was checking everything else. It was filthy. I read that a clogged inlet could also cause oil to push out of the turbo. Hoping this helps my oil issues. |

These are all the exact reasons as to why we just run the Peterson can. No pcv, no hoses to the intake just a large -12 out of the block and -8 from the heads..
