PCV System plan, what you think?

ASSISTANCE Forced Induction

Here’s what I was planning to do:

I numbered the parts so it easier.

  1. This will stay open-air as it has been for couple years, no discussions here.

  2. Can I leave this open-air? What is it actually?

  3. A mini filter is gonna go there. From what I read, having it open-air causes no problems. I might also route it pre-turbo, but i’d need to get it thru a catch can.

  4. Here the fun starts. I’m planning on routing the hose that goes to the PCV Valve to the pre-turbo piping. There would be a catch can for sure in between. Would the vaccum source be enough to vent the crankcase? (My guess is yes, but I want to make sure)

  5. I would connect the BOV and the boost gauge there where the PCV hose used to be.

What are your opinions about this setup? I know there was other threads about PCV systems, but none answered my questions.

Thanks!

I dont exactly know the negative affects of an open air crankcase. but here would be a couple of sugestions

  1. Why not get rid of all those pcv hoses (upper and lower) all together and put the PCV valve right in to the breather box on the back of the block and run your hose strait to your breater assembly.

  2. if you havent had the dashpot diaphram hooked up for year why is it even still there, :think: yank that bitch out of there:giggle:

Either way man, sound like a good settup to me:up:

here’s my current setup, which should help you out. i am running a endyn kit as well.

Whoa, there nothing on there! :rockon:

Would you mind explaining the connections a bit? IE: where is the BOV connected at, etc…

What do you guys think about the DIY catch can using a Husky air filter? I’m debating on using this or a MFactory catch can from Touge Tuning here on the board. (What is tempting about the DIY one is the size, I don’t have a lot of free space since I have ABS brakes which take up a lot of space :rant: )

you can see the white “t” fitting coming off the brake booster line. the bov will be on the one side, and the wastegate will go off the other. yeah, i did some research, and you really don’t need alot of the things hooked up to the im. now i see your in canada, so if you will be driving in the winter, you would need some of the things cause they help keep the car idling when it’s cold. until you reach operating temps i mean. if you looked on the back of the im on the drivers side, you’ll find two vac ports. that is what my boost guage, fpr, map sensor are connected too.

as far as the diy catch can, go for it. just make sure you read/research and understand how it should be hooked up. they say the welded on fittings for the valve cover are the best for getting rid of crankcase pressure. i don’t have these on mine, but we’ll see how it works. i’m gonna have a small setup though, so no big hp #'s.
hth… good luck.
