I think an illustration (like the following from a different engine type) would help a lot of people. Can anyone modify the image below or come up with a different one to demonstrate how the PCV system on our 5.4 S/C motors works? It needs to show all the hoses, the intercooler location, and arrows indicating flow paths (maybe more of the intact tract too?).

 

I can't wait to drill a Dime, and post pic's

 

Plug the drivers side intake boot and put a breather on the drivers side cam cover and your done.


Now you can use some hose and put the breather at the end of the hose where it won't get the cam cover oily over on the inner fender or something. Get some ...I think it 5/8 dia. and it will slip fit right onto the outsde of the factory PCV valve on the pass. side and install one on the drivers side...... you could run two breather hoses down the frame rails and put the filters just behind the rear bumper.. no...scratch that idea it would make a mess at the drag strip

 

Or you can plug the vent on the right side and use one of those breather caps which fit on the oil fill. Kind of like this this F150 did.

 

so if I buy the Lightning Enterprises kit, then put a dime (with a small hole in it) at the back of the plenum, I will have pretty much no problems? is this what I am getting out the the last few posts?

Boy did I open a can of worms. Maybe I should just leave it be

 

I dont think its a bad that this is being discussed. I for one will be pulling my s/c off for apten porting and realy would like to have this figured out so that when I clean my i/c i know it wont need cleaning 3 days after i put it all back together.

Thats exactly what I am doing TOMORROW! Pulling the blower...granted I only have 2,600 miles on the truck, but I'd like to clean it once and for get it while it is off

 

That's what I got from all 4 pages. The kit is only like $5. I think i am going to go with it, kinda like rob's new set up and add the dime. Rob have you filled yours with the dime yet? I am going to get the kit from Ford (pictured above) and go from there. After I install it first hand, I will come back and reread these 4 pages and some of it may make more sense.

As previously noted, the reason for the standard Lightning PCV valve that does not shut any flow off in any direction, is because of the "pressure differentials" occuring between postive pressure in the intake mainfold under "boosted" conditions, and the negative condition under "no boosted" conditions - under accelerated and decelerated conditons - and the requirement in a "sealed" crankcase ventilation system that demands a flow of crankcase vapors to be continually re-introduced into the intake system - EPA Requirements. Under the usual "street" conditions of "idle", "part throttle", "WOT", and "decelerations" under varying engines speeds and loads and "boosted and "non - boosted, high vacuum" situations occur, the "flow" of crankcase vapors and "pressures" are often reversing direction. In the non-vented to the atmosphere standard PCV system, this flow of combustion byproducts and resulting pressures in the crankcase, will re-enter the intake system - either through the passenger side line or driver side line. Thus ensuring crankcase ventilation under all conditions - and complying with EPA requirements that "nothing" be vented to the atmosphere.

PS: Interesting sideline and I'm sure I'm not the only one that recalls this - but I think it was well over a year ago that Tony( a good guy) at Lightning Enterprises began to market his "kit" to resolving the oil in the intake problem - and he got kind of "clobbered" over it by some. Now, looks like it's getting a good look at again.

QUICK ANSWER, HELLZ NO, IT'S FRIGGING COLD OUT THERE
Maybe I'll get to it today if it get up into the 20's
OR SOMETHING

I'm gonna need some alone time
My kids got his 1st sleep over this weekend,
I'm gonna have 5 screaming Sugar Pumped 9 yr olds running
around my house from 12 today to 12 tommorrow.
(If I was their Parents, I wouldn't let them stay here)

BTW
2 are twins,
that ought to go good with a few

 

Well, pulled the blower today and the IC is perfectly clean so far. I want to PREVENT oil from going in there since it is so nice and purty. The inlet of the blower did have some oil in from the intake, but never made it to the IC (yet).

Can someone show me where the cobra-like PCV valve goes on our truck please?

Excellent explanation.
for those trying to understand what im doing.
I am constantly pulling air out of the crankcase via the supercharger.
In all situations.
Never venting anything.
I have figured a way to filter this air, and dump it.
Never putting oil into the intake tract. Even under the intercooler.
ALL PCV systems allow oil to enter the intake tract. Even on your mini-van.
Why NOT use the supercharger to constantly PULL air out of the crankcase.
Not for all, but those that understand this will understand its advantages.
I will admit the dime way will work. (just blocks off the massive suction from the supercharger) BUT as all PCV systems do.
It does allow oil back into the intake track.
You will just be getting "smaller" amounts, because the supercharger is not pulling it out for you.
ONce again, Im using the supercharger. Its there, and a great thing to have and use properly.

I know, i need to produce something.
Its getting close, I have it and its working.
I just want to be 100%.
And i am. Ill be putting kits together asap. Ordering parts next week.

"Can someone show me where the cobra-like PCV valve goes on our truck please?"

No mystery. It goes into the right cam cover--in place of the OEM one. Just pull the OEM one out and replace it with the 'new' valve.
