I got me one

 

I got to apologize for getting the wording backwards on the Drivers and Passenger side, THAT WAS CONFUSING
"now it's correct".

Sometimes I think I got the backwards thing, dislezia or what ever the hell they call it. I know what I want to write but I get it backwards.
Either that, or just too many years of

Passenger side factory PCV is a POS and allows flow in either direction with absolutely NO restriction. So what happens is crankcase pressure that is suppose to be sucked out of the motor and back through the intake is instead pushed back into the PASSENGER SIDE and then internally over to the DRIVERS Side where it get's pushed up into the Front of the T/B.

With one way checks (PCV's) on both sides I assume pressure can get sucked out, but oil not pushed out ???

I will be taken my throttle body, MAF, Air Box, etc, off and on alot soon to set up and tune my Nitrous. I will let everyone know if this is keeping the oil out as time moves on

 

If I am understanding this pcv valve thing correctly, this new check vale is opposite of a regular pcv valve and stops the flow from going from the valve cover to the intake. It also stops any pressure build up from this side being relieved from the pcv valve. Would"nt all the pressure then be relieved on the drivers side and any suction from the blower pull oil from the drivers side. Would we still need some type of oil seperator on the drivers side to capture oil while allowing for pressure release from the motor?

 

Yes I believe we will still need a seperator on the Passenger side
When the snow breaks, I will DOUBLE CHECK THE DIRECTION of the Drivers Side Check Valve, maybe later while I'm shoveling.

If you want to hear what the MFG say's, here it is:

Lightning / Harley
PCV VALVE KIT
Does your’ Ford Lightning / Harley use oil, smoke on start-up, leak oil from the intake boot or spray oil all over the throttle body?
If you answered YES to any/all of the above then consider this:
The PCV valve that came as OEM equipment in your Ford Lightning’s supercharged motor is supposed to keep the crank case oil from entering the intake manifold under normal driving conditions during which the intake manifold is running in a normally aspirated vacuum mode with un-pressurized cylinders. In this positive vacuum mode any oil coming through the stock PVC valve would drop back into the passenger’s side cam (valve) cover from gravity.
Stock PCV valve shown here

However under an opening throttle especially in a positive boost mode (pressurizing of the cylinders) the airflow in the PVC system of the supercharged motor is being reversed and instead of pulling the crank case vapors out under vacuum it is instead sucking the intake air through the PCV circuit and PCV valve in a reversed direction. As the engines need for air increases the suction at the mouth of the throttle body becomes such that the tube leading from the drivers side cam cover to the intake boot (the crank case PCV air inlet tube) is placed under a reversed vacuum and literally sucks the oil laden air out of the drivers side cam cover and into the intake boot. The PCV valve should stop this airflow reversal but Ford used a PCV valve in their supercharged motors that never closes at anytime no matter which way the air happens to flow. I am sure the Ford Engineers had their reasoning, could it have been so the supercharged motor passed Federal emission standards?
When the boost becomes positive the airflow through the throttle body and into the plenum above the blower increases causing this reversal of the PCV system airflow. The use of a proper PCV valve or as found in our kit two PCV valves would stop this reverse air flow and probably should have been considered as OEM equipment to be installed at the factory. But since the factory PCV valve doesn’t close to seal off the airflow in either direction (no check valve here to stop the air flow) the reversed airflow comes up through the plastic tube that leads into intake air intake boot and disperses oil all over the throttle body even forming puddles in the boot. The oil draw with the stock Ford PCV system is pretty much constant, increasing as the engines RPMs increase.
After installing our PCV Valve kit, you will find that there will be no oil residue in the air intake boot nor being sprayed all over the throttle body and coating the plenum chamber above the blower. Our PCV valve kit allows the pressure to be released out of the passenger’s side cam cover and will prevent the PVC
circuit flowing air in the reverse direction.

What are the benefits of keeping this
oil out of the intake?

What are the drawbacks of allowing this oil in the intake?

The supercharged 5.4 liter Ford motor has an air to water intercooler that cools the intake charge coming from the blower
and going into the cylinders. In order to efficiently cool this intake charge the air passes through cooling fins that transfers the heat built up in the air from compressing the intake charge to the liquid coolant that circulates through the intercooler. How does this oil misting coming from the PCV system affect the intercoolers fins and in turn affect the cooling capacity of the intercooler once the fins are oil soaked and covered with the fine dirt particles that find their way through the best type of air filtration device not to mention the low restriction type that most high performance enthusiasts use on their vehicles.

You will find that after installing our PCV kit that your oil consumption caused by the above described condition will be non-existent

. Other suppliers market a kit or component (oil seperator) that was originally designed for use on stationary air compressors, either as air dryers or oil / water separators. This method employed to eliminate a simple PVC problem can be expensive, messy and time consuming to maintain, hideous under the hood and difficult to install and how long can these devices work as most are designed to be mounted on compressors that have only a one-way high pressured air flow.
Our kit is easy to install (15 minutes or less) with small screwdriver

Links don't work, where can I get this?

 

Its a post from 2003 - try the vendor name in the picture - see if they still exist

here you go

I've been using this exclusively for about 3 years now and, although it doesn't keep all the oil out, my intake stays fairly clean compared to w/o it! I'm sure there will be plenty that say it's useless though

 

I agree

But dam I talk too much, I hate reading my old post *&#@$(@#$%()@#$

After also using it for years I agree 100% with ED
It takes care of MOST of the oil sucking problem, (actually it takes care of "1" of our oil sucking problems, but we have 2) But as he said, it takes care of it enough where as you will NEVER have to clean your intercooler again (or worry about it getting oil soaked) with it you'll only get a little oil film in the Upper, but you wont have oil in the Inlet Boot or FRONT of the TB.

AMOF after my first Built motor within 200 miles my inlet boot and TB were dripping in oil, I put the kit back on and WAM NO MORE OIL.....

 

Heh, I still have this kit sitting in the desk drawer from which I'm typing this from now. Checking my oil, the level on the stick is in the same location from oil change to change oil change and I have no smoke on startup or anything, albeit, my L only has 8,500 miles on it. Still wondering if this kit would be worthwhile to install. So which brings up the question if we can get some more updates on the performance of this kit since this post is from 2003 - you guys should have some pretty good feedback by now if it works or not.

 

Nice.... I think I might finally install my kit this weekend.

 

It certainly can't hurt (like possibly some of the other fixes always mentioned) and it installs quickly and cost nearly nothin...what have you got to loose !!

Driving habbits and mods DEF play a part too, I think part of the reason I had such a problem with only 200 miles on the orig Built Motor was the amount of Boost I was running, I mean chit we had that thing over 25lbs of Boost for a while there (another words the oil problem seems to get worse with more boost / more power)

As for updates, you guys prob remember I also incorporated a Check Valve into a Breather for mine many years ago, that happens to work extremely well, (I always used that too) here's an older picture of it


It must work because JDM came up with a simular set up on my new Motor. I'll try and take a pic of it today, then post it.

Bottom line is, for some of us we MUST get that pressure out or it is going to get pushed all around the motor

 

I bought one, it was a waste of money cause it did nothing. I emailed the person and he gave me bunch of crap!

 

Hhmmm... any other comments? My L is stock except a open air filter/intake. Should I bother with this kit?

 

Rob, I am interested in your setup can you tell me where ya got it from or what you made it out of?
