#62802, "Question and Thoughts about Catch Can!"

Sup guys.
Before I say anything, can someone verify this connection for the catch can!

The one that use to have PCV valve is this:
valve cover - hose - PCV - hose - catch can
The other hole that use to have a breather filter is this:
valve cover - hose - catch can.

Is the above connection correct?

Ok now, today when I am playing around with the Catch can, I have a thought about the oil trap by the catch can, why trap the oil then dump it out and wasted them (also lower oil level) and not just re-route the catch can bottom value to the oil pan (the turbo oil return line) so the oil can be reuse or in circulation??? why not?

Just a thought!
Thanks.
Gil

No do not touch the hose that goes from the VC to the intake manifold (the one with the PVC). Only the one that would normally go from the VC to the intake pipe.

2nd I'm not going to answer that question about rerouting your oil into oil return for the turbo. You didn't think about it and if you did you'd realize why that is a monumentally BAD idea. Here's a few hints: 1. Oil is BLOWN from your VC to the catch can from positive pressure. 2. Oil drains from the turbo from high pressure in the bearing housing of the turbo, low pressure of the oil pan, and gravity. You figure the rest out.

OK! I did thought of that about the pressure thing.
But I also thought about the breather filter on the catch can, since it is kinda like a open system to the outside from the breather filter, so I am thinking the PRESSURE from the valve cover will be lost from the open! I guess not.

Well, About the catch can connection, you ^^^ mention about leaving the PCV hose to the intake manifold, and ONLY connect the other one (the one with breather filter) to the catch can???
But I read some post that people say routing BOTH hose to the catch can is the BEST, am I correct? Is that why the catch can has input?
Please give me more input!
I will be installing my catch can tomorrow!

THanks alot guys!
Greatly appreciated!
Gil

P.S.
For now, I unhooked the PCV valve hose to the intake manifold.
My current connect is this: VC-hose-PCV-hose-outside
Then I sealed up the intake manifold side. and I still have OIL coming out from the hose after the PCV valve once a while I boost hard. So should I route it to the catch can? and should I leave the PCV valve inbetween the hoses???

For the love of god and all things holy, just install it. it's a goddamn catch can, not a freakin motor. it's not rocket science for chrissakes.

Me either. I never get any blowby.. Only time I did, i hot-lapped the local 1/4 mile track 6 or 7 times in a row with no cooldown, had enough to wet the breater filter.

Damn guys.... I thought at least some of you will give me some good feedbacks... lol.
Anyway, do I worried about why I get so much blow by. so worried.

Well, My MAIN question for this post is just that, if I SHOULD hook up both valve cover hose to the Catch can, or should I just hook up one. that's all!

THanks guys thou.

That's really up to you. No one is going to tell you what you should do. I've seen them hooked up both ways. Personally, I have both ports on the valve cover running to my catch can, and I removed my PCV valve. If I drive my car really hard for a while, I'll get a little blowby. If your car is getting a lot of blowby, you might want to do a compression check to see if your rings aren't sealing.

You are not your job.
You're not how much money you have in the bank.
You're not the car you drive.
You're not the contents of your wallet.
You're not your fu**ing post count.
