When I finally got my truck finished about 6 months ago I was blowing my dipstick out, just a wee bit of crankcase pressure, I capped off the port to my throttle body and and the port ontop of my manifold, I am currently running a line from my front nipple on my right hand bank valve cover to a breather and its mounted on my firewall and i also have a PCV valve out of a thunderbird turbo coupe with a line on my left hand bank rear nipple going to a breather mounted on my firewall, it took care of my dipstick blowing out but i dont like how it looks and the breathers are mounted right under my cowl and they are blowing just a little oil residue out, I am thinking about fabing a catch can set up on both sides
I was wondering how some of you guys were taking care of your crankcase vent problems, I have seen some posted on here just trying to get more ideas
Thanks

 

I dont have any pics, but i ran the Passenger side valve cover to a seperator and then to the Airbox. The driver side is factory.

I just gotta fix a leak on the turbo drain but it seems to work so far.

 

I called Rev Extreme, and the owner walked me through the thought process of their catch can and vent system. My truck was smoking on decel, and after buying their boosted application can, then hooking up the hoses like they suggest the smoke was gone.

 

Same here. Rx can is the best out there for boost IMO

 

That Rx can doesn't look vented. Where is the crankcase pressure going under boost?

 

What do you do with the pass side? That looks nice and clean.

 

Put a filter on the oil fill cap so it sucks clean air through the motor. That can is setup with 2 check valves

 

Here's my setup. Mightymouse catchcan with internal PCV valve. I drilled out the factory PCV valve on the back driver's head.

Capped TB. Passenger VC port goes to the pre-turbo air filter. This is what makes the system positive crankcase ventilation (vacuum pulliing vapors out of the crankcase while in boost).

 

If I remeber correctly it vents back through the front side of the turbo under boost, as there is a vacuum created when the turbo is spooling. The guys at Rev Extreme can answer all your questions on how a proper boosted PCV system should work. My conversation with them was a learning experience.

 

My plan is a single unvented catch can in the PCV line with a check valve between the intake and can. Then an oil filler cap breather on the passenger side valve cover. Cap off the TB and passenger side valve cover tubes. Pretty simple IMO, and no oily air going into your turbo. Only downside is you might have some oil fumes when in boost.
