Re: PCV Delete...
I did the same as Wicked. For quite a few miles I ran my car without the pcv system. Had to go back to it because of all the blow by and oil that was coming out of my mini breather had stuck in it.
No harm in running without it. Doesn't cause any vacuum leaks, etc.

Re: PCV Delete...
I wonder if there is a way to run some type of remote oil seperator that drains back into the oil pan? Even better if you run an oil drainback for the supercharger, you could just piggyback off that system.

Re: PCV Delete...
In a good sealing motor, there wouldn't be enough oil to worry about it.

Not trying to highjack or get any fires going here but If the PCV does not use vacuum, then how come when you remove the valve with the car running and place your finger over the valve hole there is enough vacuum to suck your finger to the hole?

Re: PCV Delete...
This topic has been argued about 1,000,000 times on F150online.com with no real results.
I run a 03 Cobra PCV valve and the "dime" mod on one of my lines to restrict the flow under boost and I still get a little oil in the intake, but not as much as other people.

I'm not saying it doesn't use a vacuum source, i am saying the crankcase is not under negative pressure. It only uses to vacuum source to create an airflow....thats why they call it ventilation. Yes, if you disconnect the "high" side and feel the hole it will create a vacuum, but that side is not normally plugged. It is open to your metered air source BEFORE your throttle body. I tried plugging the pass. side and leaving the driver side hooked up to the vacuum but the engine vacuum cause some of my seals on the front of the motor to start "singing" as they created vacuum leaks. As far as how to run a drainback, you could always connect a hose to your dipstick tube. And I found out about the vacuum pump for ring sealing in racing. The general rule is a max of 12 inches of mercury...more than that and you need special seals, specifically intake end seals or you will suck them in...they sale valves to limit vacuum in the crankcase. He said his normally reads 3 inches or so, but 0 at WOT.

Like Wicked said, the crankcase is under positive pressure.
