So i searched in UTH and FI, but didn't find the answer.

Most of the catch tank threads were in UTH, and most everyone used the catch tank on the PCV, saying that the crankcase breather did not have much oil if any. A lot of these guys were n/a though.

So have you FI people noticed any oil entering the intake piping through the breather hose (more so than an n/a car)?

Reason i ask is because i've been turboed for a few months now, and i recently noticed a layer of oil on the inside of my intake piping. I thought it might be my turbo leaking, but i took the turbo off and inspected it and it was not leaking. My thoughts are that it might be coming from the crankcase breather? what would your experience tell you about this?

 

I did a quick image search and found two cars--the J's Racing Ap1 (yellow) and AJR car (white)...sorry they are N/A, but i wanted to see how some well known cars were doing it. From the look of the J's car, it looks like there is a fair amount of oil in the blow by and it's n/a.

Now the setups: from what it looks like, the J's car has plugged off the entire PCV valve (on both ends) and the AJR car has plugged off the PCV port on the IM, and joined the other end with the blow by going to the catch tank. Anybody have any experience/comments good or bad about the way the hoses were routed? After reading the UTH catch tank threads, i am inclined to believe i should only be hooking up the catch tank on the PCV hose and leave the blow by alone, however these two race cars show otherwise.
