Boost + PCV?

ok i been venting the pcv and cam cover breather to atmosphere. now i just got CFM boost freindly PCV(motorcraft EV-111) and going to hook up a filter to the cam cover breather. i did do a seach and didn't find what i'm looking for.

What are signs of my crankcase getting boost pressure? And is running the boost friendly PCV going to be a problem in the future?

any info would be great thanks guys.

If the crankcase becomes pressurized you can blow out the front or rear main seals. I would guess if you have a boost friendly PCV valve you would be ok. Can you post a picture of this?

Why would you want to add anything that sucks the hot oily contaminated air back into the engine

Tom,

Are you talking about the PCV valve or the vent?

1) to keep the hot oily air from building up on compenents
2) to keep the hot oily air out of the car when using the HVAC
3) to keep the hot oily, dripping, air off the ground
4) to keep the hot oily air out of the atmosphere
5) to stay legal

Tom I know you're a renowned tuner, and you build race engines, but we're every-day people here and our cars are daily driven for the most part.
There's perfectly good reasons to keep the PCV system hooked up for daily drivers.
If it involves de-tuning slightly and lose 5hp then so be it.

I currently vent the crankcase and valve cover to a catch can and then to the atmosphere and it's terrible.
The odor is unbearable when the car isn't moving and the HVAC is turned on.
There's also a sludge building up under the valve cover, and in the crank case.
I'll be hooking up my PCV system back up soon.
I haven't decided how I want to go about it.
I'm considering a dual valve system that will still allow the crankcase to vent when it boost.

Sorry if that sounded like a rant, but I've not been enjoying having no PCV system.

I have an '06. Do our cars draw fresh air for the HVAC system from the same location?
It doesn't seem to matter where under the hood I vent it, it still gets sucked into the vents.

i think i'm going to run the pcv on the section side of the supercharger w/a oil separator. so the crankcase will only get some vacumm from the supercharger sucking away lol.

yea the smell is not good. thanks for the info guys

Sporadic : If you are a tree hugger and feel a few drops of oild will save everyone then hook it back up to make your self feel better not a problem

1) to keep the hot oily air from building up on compenents
**If the hoses are run down below the "K" member there isnt any components to build up on

2) to keep the hot oily air out of the car when using the HVAC
*If the hoses are run down below the "K" member there isnt hot oily air to come inside

3) to keep the hot oily, dripping, air off the ground
**Yes you will get a few drops when you park it isnt a perfect world and there is some give and take to everything

4) to keep the hot oily air out of the atmosphere
**Sorry but if you run it through your engine it gets burnt and come out somewhere and if thats you argument get a bicycle

5) to stay legal
**So lets see you have installed an illegal turbo kit and illegal tune and more then likely Exs system and your worried about a vent hose ?

There is places to run the hose where you wont have any or little of the issues above

Pulling air from the Valve Cover and the PCV will load the intake with oil , lower you octane when you get a good bit of oil in the intake and do hard pulls , this air is full of oil , water , and contaminations that you dont want going back through your engine if your doing FI and being a daily driver has nothing to do with it , when you go wide open throttle the engine does not know if your going home from work or going down the 1/4 mile track
