If you see oil in your throttle body, that means it's accumulating towards the back of the intake manifold, being too heavy to get lifted into the first 7 intake runners. The oil enters the last runner on the passenger side, and follows that up and over into cylinder 7 next to the brake booster. For high boost or borderline tuned applications that may end up to be a problem. For low boost motors it mostly ends up as an 'oil in intake port 7' curiosity when someone removes their intake manifold.

I feel pretty strongly about this one (as some of you may know). I would ask you this simple question. Would you run gas with an octane of 70 or so in your boosted motor? Well, that is what oil contamination can do to your effective octane.
I spent 6 months fighting KR problems on my motor. Guess what the problem was all along.

Re: pcv catch cans (mdhmi)
It was the PCV system in general. A catch can will help, but I'm not sure if it will solve all problems related to oil contamination in the intake. I removed mine completely and I'm now making tons of power on pump gas.
My situation may be unique due to more blowby... I just know that the PCV was causing all kinds of problems on my motor.

Re: pcv catch cans (king_pin)
I'm not going to take credit for anybody's hard work in researching a senseable EFFECTIVE solution to overpressure of the crank case under boost conditions. We now buy our oil seperator kits from Lingenfelter. They did the home work and they sell a great kit. Give Tim at LPE a call or JP over at 21st Century. Those guys hooked Xtreme up... they will you too! I will be stocking LPE's oil seperator kits as well... as soon as I catch up with the current/past customers in need of this kit.

Re: pcv catch cans (drcoffee)
I am still investigating, I see a baffle , but no filter.....As far as a sight glass, i see no need, just drain her every week ...I am sure you are not going to get a lot of oil. I dont see why an air line filter would not work , oil seperator??

Re: pcv catch cans (dads01dream)
Check out the Evac Breather Canister from Shogun Industries. http://www.shogunindustries.com/cgi-...oducts.htm#new I installed this unit on my car last week. The F1-R S/C and bracket takes up the space where it would normally be mounted, so I made a bracket that comes off the back side of the S/C bracket and mounts the canister along side the passenger side fender well. I also made a right angle air manifold that mounts on the firewall. I made braided stainless lines to connect the valve cover output to the air manifold, from the air manifold to the canister, then from the canister a line connects to the original destination point. I polished the canister, both brackets, and the air mainfold...it really looks great.

Re: pcv catch cans (blu00rdstr)
I'm confused, isn't the line that goes to the air fiter the only way that oil could get sucked into the intake? From the picture that line has nothing to stop oil from being sucked in. I talked to Andy about this and that is where he said to put the seperator.

I dont see why an air line filter would not work , oil seperator??I initially just had the ACE Hardware air/oil separator with a checkvalve. The oil level in the glass never got higher than 1/4". Oil in the glass would splash onto the filter which would saturate. Vacuum would then draw oil and air from the separator.
