pcv evac question

[qwikhuh94]

ok guys...countless hours reading post from up to 7 years ago...head is spinning..lol. i'd appreciate any advice on what i plan on doing.

here's my plan, tell me if i'm doing it right. 94 383 vortech/aftercooled, maf is on the blow side near throttle body. i plan on leaving the stock pcv valve (driver side intake) intact. on the tube from passenger valve cover to throttle body, i plan on running a hose from that valve cover fitting to an oil/air separator (husky one from home depot #401910) and from the separator to the intake/suck side of the vortech intake pipe. i will also plug the hole on the throttle body that was connected to the tube from passenger side valve cover.

i know not the most efficient setup, but hoping it would work for the time being to relieve some crankcase pressure under boost. another question i was wondering about, since it is maf metered air and not running a speed density tune, would the tube running from the passenger side valve cover >> separator >> blower intake suck side tubing matter since the air was already "measured", i would be re-introducing metered air back in front of the maf, would that really affect anything(if that makes sense)?

appreciate it guys...thanks!!

You're on the right track. Here's what I"d change.

Run a tube off of the PCV to the blower inlet tube. This way, should the PCV fail, you won't be pushing boost into the crankcase. Instead of the oil/water separator, for around $60 you can get an Allstar Performance vented breather tank. I'd run that because it's filtered, and vented to atmosphere. If you're running a significant amount of boost, you might want to run breathers off of both valve covers.

Appreciate the quick response!! I'll eventually get a more elaborate setup over the winter, but do you think that the way I plan on running it, it work out fine? I already have this stuff in the garage and plan on throwing it on tomorrow.

If you wanna do it that way, I would ditch the husky rig and run a real catch can for pull through vacuum.

Ive seen the husky setup work on an na car, and spent a lot of time actually adding one on each side of mine to end up ditching the whole setup and ordering a header evac kit from jegs. Summit doesn't have it. Granted its a little more work and you can't have it tomorrow, but it works great and its only like $30...

Making you silky smooth...

ty guys..going the garage parts route it seems till I get more time for better set-up. Funny thing is, this is the only site out of 4 that actually gave me advice...!!!! The only other comment on the other sites was about my non capitalization..lol

thank you again..appreciate it :cheers:

What is the best setup for the PCV system when you're not running boost?

I just posted a question about this on a new thread I started.
