You've all seen this by now, bought from E-Bay
IT WILL WORK
You can not blow through the new PVC Valve "OR" the Drivers Side additional PCV Valve one way. It will not allow reverse flow.
As easy as 1 2 3


Passenger Side
Install new PCV Valve, THIS ONE IS ALSO A ONE WAY VALVE
and will not allow reverse flow.

 

Drivers Side


Thats the final look, basically your putting a male by female extention in the ell that has a check valve in it.

 

Isn't that the driver's side with the ps resevior and master cylinder??

Looks like time to go spend some more $$$ on the L.

 

Rob what do you mean by it will only suck into the motor not out? This is on the driverside right? Why would you need a check valve on that side?

 

Umm, I think you got a little ripped off there Rob. All PCV valves are one way. Nothing will ever go INTO the valve cover from a PCV, that's not what it's for. Air is SUPPOSED to go from the valve cover to the intake. Under vacuum conditions, the PCV is pulled open and crankcase vapors are allowed to vent into the intake stream, and be burned out the motor. During zero vacuum, and/or boost on a supercharged vehicle, the PCV closes off, blocking the valve cover to the intake. If you turn the flow of the PCV around, it's then useless and you might as well just block it off at that point with a 50 cent ball bearing like I've been saying for years. Keep in mind however, that if you stop the crankcase vapors from exiting the valve cover via the PCV, you need a breather cap so pressure doesn't build up in the crankcase.

 

Reread this:

stock PCV does not close off...should, but doesn't....



I think Rob just got the into part backwards--he knows it's being pulled (out) toward the supercharger.....the driver side is the one that only flows in.
He's trying to help!
Quick Rob, Edit, edit, edit!


Hey, but now that more people are here, can anyone answer this at all???? (3rd time asked )

ALSO, 1. where is the oil separator that the factory "vacuum line routing" sticker under the hood shows?
And 2. where does the line go that tees off between factory PCV and supercharger???

 

Your motor is dirty.

 

Ok first let me say I'm sorry for marking "and writing it backwards"
Schitt, I'm confused enough, plus I feel like Sal just kicked my *** or something, HEHEHEHEHEHEHE, J/K Pal

Sal, but our PCV Valve is useless you can blow through it either way with no problem, I have it right here in my Mouth Now, "Hey this will make a good Spliff holder"
YICK IT TASTE LIKE OIL
Dam you sure can blow through it in either direction "with no differance at all" no matter what position it's in. So the positive one on the PASSENGERS SIDE will help that .

Then as for the DRIVERS side, yes they give us a CHECK VALVE that WILL NOT allow reverse flow there either.

SO YOUR RIGHT, this is exactly the same as your ball bearing trick you've been saying for years. But where the hell do I get a ball bearing I guess that would have been cheaper.
Sal, you need to start selling ball bearings

DAM, YOUR ALSO RIGHT that I would need my breather back on, otherwise there is no way for the crankcase to vent ???

Ok so this combo with my Breather (and check valve I use) WILL DO THE TRICK THEN
The Breather will allow the motor to vent, but not suck in un-metered air (because of my check valve), meanwhile these two positive type valves in this kit will allow the engine to do it's normal thing but NOT FLOW in the wrong direction.

DAM WHY DIDN'T I JUST BUY A BALL BEARING ???

 

Your motor is STILL dirty.
What are you going to do to address that problem?

 

V, dirty is putting it mild.
The ****ing inside of the hood is even salt infested, along with the whole motor too
GOT DAM THIS ****** SNOW
and another storm coming tomorrow.

 

OK, what about this. If truck is idling, pull line off PCV; there is big-time vacuum there. Put it back on. Pull line off driver side valve cover. Put thumb over valve cover and leave it a second or two. Notice vacuum building up. Hear air rush in when you remove finger. There seems to be a small amount of air flowing thourgh engine. ???

If you have a breather instead of oil cap, will back of supercharger not be pulling air through pcv, through the new breather--instead of somewhere else (least resistance?)--hence the unmetered air.

As soon as I can get parts together, I don't want to pay the 30$, I still think the driver side one-way, and an oil coalescing filter between PCV and supercharger should solve BOTH issues.

Still, how about them 2 questions of mine???

The oil problem doesn't have anything to do with the PCV not closing off. I read the little info thing on the sellers ebay ad, and this person does not know how a proper PCV system works. The PCV valve is not designed to "block oil from entering the intake". Air is SUPPOSED to go from the valve covers to the intake, not the other way around. Putting one way check valves in is just a waste of a valve, you might as well just block it off completely. Plus if you never let the valve covers vent pressure, you'll be blowing out gaskets in a hurry.

I designed a proper kit a few years back, maybe I'll put it into production.

As for where the line that tees off the PCV line goes too, it goes to the very back of the lower intake. It cannot be accessed while on the truck, you have to remove the intake to get to it. The fitting on the lower intake has a small orifice in it, and allows a tiny amount of boosted air to pass through it. I experimented with blocking it off at the intake one time, and it caused some weird deceleration issues with boost and the blower, so we need it hooked up.

 

Actually if you really want to eliminate oil in the TB and blower you
completely disconnect the pcv hose that goes to the upper intake which is
really called a throttlebody spacer. Cap it off at the blower and put a cap
on the tee that is between the lower intake pickup(down behind the intake)
and the pcv valve that is in the passenger side cam cover. You also change
out the POS stock pcv with a Mustang pcv. Mustang valves seal off when you
blow backwards through them. Now not only are you NOT blowing backwards
under boost through the pcv you are also NOT recycling the blower since the
upper port is capped off. I know your asking well what does this do for
A/F's? It does not change A/F's. I know because I did before and after dynos
where the A/F's were checked.
Just my .02 and the driverside is NEVER blocked off and their are no valves other that a pcv..

 

Please do, that way we can get the right part the first time.

 

Thanks for the answer Lightning Tuner!!!

I questioned about the logic of the "pressure? blowing back through pcv" in an earlier post. I'm still not sure where folks are saying this pressure would come from---there is big-*** vacuum being pulled into supercharger, I can't believe the pcv would ever see pressure from that direction.

But, how can we keep oil from being pulled up out of driver side into intake boot?--other than having an oil coalescing filter in that line as well---which was also mentioned by (?) not to work as planned.

Now if I can just decipher the rest of that vac line routing chart........

Am I reading this right--it looks like if I disconnect the fuel line from the gas tank to the engine, I will get less oil in the intake.

Dangit, I'm buying an electric car next!
