Highly Dissappointed....

[MRX]

i said it in another thread but theres no real hardcore warning signs that the pcv valve has gone out. I remember taking mine out when it went bad and air was able to pass through both sides no matter which side i blew from. So when it does go out...and it will, how will you know? Better safe than sorry, its not like its alot of money.

im not booted yet but i put one on anyway... i relized today that the arrows poiting away from the intake mani....which im guessing is wrong, correct? its still collecting oil tho and its only been two days......... i am gana fix it so the arrow points twords the intake mani tho, unless i here other wise

[westsideaccord]

Arrows go toward suction, ie turbo intake pipe!

[Mike]

yea so on an n/a egine it should go twords the intake manifold right?

[mullet]

Yes, arrow towards manifold

I have the same catch can

[Lemniscate]

A PCV valve works by sucking crankcase air into the intake manifold after the throttle body, when you are at idle it is open, free to suck in as much oily fumes as it likes from the crankcase, then when you go full throttle it closes so that you dont get any oily fumes going into the engine (prevents detonation) so then if your boosting whatever psi it forces it shut, not open. The only way you could pressurise the crankcase was if you had your breather tube connected to the charge pipes.

this is not what i have seen

people who run pcv lines to boosted piping often get massive oil blow-by

the pcv system is funtional at all times
this vaccuum in the crankcase can often get you more power thru less resistance on the intake and power strokes.
it is not uncommon to see an electric vacuum pump on drag cars for this purpose.

hooking up the pcv line to the piping before the compressor inlet will probably net quite a noticeable power gain if you previously had it set up incorrectly.

bump because stock pcv systems on a boosted setup WILL blow your ringlands.

Just experienced this last night on someone else's car. I warned him...

It could have been a mix of too much power on a stock block and a stock pcv system, but who knows. The motor might have just handled the power well enough if he had a properly plumbed catch-can.

Quoting myself from 2 years ago
My statement is incorrect and as d112crzy said, yes the PCV should be removed and a catch can used

Yes, I agree with your correction as I was about to. I feel many people don't understand the reasoning behind crankcase ventilation and are concentrating too much on the boost side of their turbo systems. Problems will come, some already have experienced them, need to envision the ENTIRE system. I too have wondered was Carlos did in the lack of.

i just purchased mines. should be here in about 5 days.

[WiKKeDV16]

thank you ... for not being on my shit list for not having one.!! haha

like your setup btw.. looking good boss

i have my oil catch can but no one seems to reply to see how they hooked it up on a h22..

do i have to put 2 ports on the valve cover?

maury

btw i have done research and just found couple of f series and a shit load of b series set ups. i have asked around and no luck..

maybe some one will help me here.

You just need to have sufficient outlet volume from crankcase pressure. The easiest way to do that is to run 2 smaller ports, rather than one large port.

B series are different to F series - They can somehow tap into the block to relieve the pressure.
