I drove about 40,000 miles on my cusco can the same way you have it installed and it never threw a code.

 

Hm. I've found that I was blowing oil through the fresh air vent in a long left hand turn, followed by a hard right hand. (buttonwillow CCW, coming out of Talledega into the bus stop)

I hooked up a catch can to my fresh air vent and all was solved. I was blowing smoke really badly. I suspect that oil splashes up onto the fresh air vent and comes out. I didn't get much in my catch can but it solved my smoke screen problem.

 

yeah, i've talked to a couple of friends and they said it was weird i was throwing a code also.

i'll connect it the way Slows2k says and see how it goes.

thanks for the input guys

 

I don't understand why there is so much confusion about where to hook the catch can up! Air flows only 1 direction through those hoses! It flows IN through the front hose, and OUT through through the PCV. The PCV prevents air from flowing the other direction, and the manifold has a ton of vacuum pulling air in. I have never experienced, or heard of, smoke occurring on left handed turns, or on right handed turns under heavy throttle (little vacuum). It only seems to occur on hard right handers with little or no throttle at high revs (high vacuum, high flow from the PCV valve to the manifold).

 

I never saw the problem at AutoX or at primarily left hand tracks. I have at Buttonwillow counter clockwise and thunderhill the normal direction.

My car would spit out smoke as I got onto the gas coming out of the corner, well into vtec.

 

ok i hooked up the hoses how they're supposed to be, one to the PCV and one to the intake manifold.

while i was doing this i figured out why my car was throwing a code. apparently, i unhooked one of the vaccuum hoses while messing with the install...

thanks for the help guys.

 

Good to hear it's fixed

 

Please clarify. Define "much". What makes you think that you were blowing oil through the fresh air vent (air inlet near cylinder #1?)? That would be a LONG distance for oil to travel against the flow of air...

 

I want to hook up the catch can to both the breather tube, and the PCV valve, because when I am in boost, the air pressure in the intake manifold is greater than the air pressure in the crank case, and therefore the PCV valve never opens, and it shoots pressure out the breather. What do you guys think about that idea?
