Default Crankcase Ventilation Mod w/Pics

Drill out PCV from the bottom and remove white valve. Drill PCV from the top to enlarge the hole to move more volume.





Plug PCV tube in lower plenum with a 1/4" NPT plug or vacuum cap over tube.



Connect drilled out PCV hose to catch can. Attach vent hose to catch can exit and vent to atmoshere.



Run drivers side breather hose to turbo intake as is.



I am going to Sebring on Sunday to run this setup. It is basically same thing Sharif did, but he ran his driver side breather to the catch can as well. People asked for pics so here they are. I did not drill out the drivers side breather hole as Sharif did because I did not have time to remove the valve cover, but that may need to be done. This setup above effectively doubles the crankcase evac capacity under boost.

The hose that you used on the driver side, is that new? Reason I asked is because I used some tube not designed for heat+pressure and it ended up collapsing. Just making sure the hose is the correct kind.

It's transmission hose. It's rubber over braided nylon. It looks sturdy enough. Thanks!

Larry,

YOu should put a breather on the top of your catch can instead of running another length of tubing. the more tubing you have, the greater the effort for the crankcase pressure to escape.

..............and don't forget to either put some teflon tape, thread sealer, or some Loctite on that 1/4" NPT plug. You don't want a leak there.

I noticed that since you plugged the intake manifold the crankcase wont be under vacuum as you are decelerating, did this cause any problems?

^nice but too much, if you want vacuum and your boosted. hook up the other side of the hose/line to the intake charge pipe. that way you will always have vacuum and pull gases out

Would you mind dumbing it down a bit more? Pictures help too.

ok I thought Jet explained it well, but he I go...

if you have a Catch Can and FI'd Simply follow accordingly:

Locate Passenger vavle Cover. (take off engine cover)
you will see a line going from the Intake Manifold to the PCV (front of the passenger vavle cover)
in that line there is a check vavle. keep it for future use.
go and buy from your local store hoses that are somewhat heat resistant.
also buy a cap (you will plug the nipple coming of the front of the intake manifold)
now from the PCV its white. run a line to a catch can. and the other side of the catch can you can run another line and just let it dump. to the ground but make sure its not touching anything super hot. away from your exhuast manifold. or run that same tube to a intake pipe. before turbo

thats basically it

I see alot of pictures from the rear driver side valve cover and i see people posting to take that hose to the turbo intake.

Anyone have pictures of what needs to be done on the driver side.
