What the hell are you guys doing? I took Sal`s(PSP) advise. I blocked the pass side PCV tube and added a breather cap. No oil what so ever at the throttlebody or intake boot. I used a metal tire valve stem cap to block the PCV hose at the PCV elbow. I stole it from some kid`s bike, cost me nothing. The crank-case vents out through the breather cap. Once in a while I clean out the breather cap with some K&N cleaner. Works for me.

 

Your completing the loop. The metered air that enters the drivers side boot enters the rear of the plenum.

air must make it into the intake plenum to assure that the air/fuel ratio is correct. If you completely block off the PCV system, the air/fuel ratio will be adversely affected. The air entering at the drivers side ( metered airflow) in the PCV system must make it all the way to the intake for the same reason. What this means is, if you completely plug the plenum, then you must bypassed the PCV system completely, both the inlet and the outlet air transfer paths must be blocked. You just can’t block off one and not the other. But I have found if you leave the PCV system intact and just restrict the opening at the plenum it reduces the heavy oil in the air stream from reaching the plenum. I also have a separator just above the factory PCV valve, which picks up an 1/8 of the oil it did with out the restriction................I have removed my one way valves .... Rob, that double hole looks sweeeeeet..but one should be enough... measure the Dia. of the factory plastic tube and you will see that one hole reduces...two is about the same as factory.

 

That be a big hole Gator......put the drill down and step away from the truck

 

No RED 92, you CAN block off the PCV valve without adverse effects on the air/fuel. The crank-case still will vent through the breather cap aswell as the PCV tube on drivers side venting into the intake boot. The air/fuel mixture is adjusted through the chip. This does in fact work

 

The crank-case still will vent through the breather cap......who said anything about a breather cap in this thread.............. come on Jim.. read before you chime in

That venting your referring to Jim........... did you know that the PCV tube on the drivers side supplies crankcase venting and of course air from the airbox and both are metered air.

I never said you can not block of the PCV system. I recommended blocking off the PCV system in the other thread on this subject as the easiest and 100% solution to oil in the intake system.

.. but I recommended blocking it all off...not just pluging the plenum because this will affect the air/fuel mixture if you only plug parts of the factory PCV system, but if it works for you have at it.......heck I've been running a 6 pound pulley without a chip for 3 months now and it runs fine ...so it must be ok ....

This brings us to where we are now in this discussion.
Modifiying the stock PCV system which you do not have if your running a breather cap. Some want to stay emmisions legal.

yes, I agree... The air/fuel mixture is adjusted through the chip.

metered air.

Rob I failed to include something about my setup..... along with the restriction I also have wire mesh from an air fliter in the 3/4 in. line that I tight slip fit over my factory PCV...I think this plays a big part in keeping oil out also ..baffling..and the restriction at the plenum reduces vacuum and psi. form the PCV system reducing the ability to pull oil up through the hose and the wire mesh. It helps catch the oil before it reaches the separator........ looks pretty bad..(its in the "see what works" stage). I'll figure something out to dress it up....but its working for me

Great Info as Usual Red, great info everyone

BTW
Love the Red SVT on the Eaton Red

As soon as I get a day above freezing out there,
I'll stick the Dime in and report my finding's as time goes on

 

ya ya ya....Well I have zero oil in my intake !!!!!
I went to "Auto-Zone" and asked the guy at the counter how to fix the oil and the intake problem......well he came out to my truck and installed this....there pretty helpful there....
so I'm not the sharpest tool in the shed when it comes to homemade mods.......thats why I like to keep the hood closed

Steele, I pulled the line of the back of your plenum and it was dripping with oil!!!!! thats probably worth 2-3 tenths in the 1/4 mile Also why I run 12's without traction bars wheel hopping..(its because of that sweet separator setup)..I installed some traction bars sunday..... so I can keep my driveshaft under the truck....no more wheel hop.


I think I'm going to see how much oil the the baffle in the 3/4 line is keeping out....vrs. how much the restriction is keeping out buy removing the dime...

Lets buy some breathers and get rid of this factory PCV system......I'm sure I can" rig up "something that will keep the breathers from getting oil everywhere.









UPDATE

I removed my restriction.... the 3/4 hose has a hose inside it attached to the PCV valve outlet that has multiple holes in it surrounded by mesh.........the 3/4 in line is about 10 inches and the hose inside is 7 inches ...its working well as a baffle... still just trace amounts of oil in the separator...at this rate i"ll empty it every six months....

 

Have you pulled the upper and lower intake to verify this? Or are you just going by whats in your throttle body?

Seperators are gay...

--Steele

 

no....but I used a borescope from work..... remember I only have 3.3k on my truck and I've been playing around with separators since 1.3k..and I didnt add mods untill a 2.9k... there is no oil in there. Now your trucks a different story.. it has a 3 inch deep pool of oil in the intake galley and your intercooler is as black as your truck .... quit lowering your octane and do something about it......separators are not gay, maybe metrosexual...but not gay...now he/shes in Louisiana are gay

 

Hey RED 92! thanks for the link. I know sometimes I need to be walked through things.
Now for some advice.
Since you have done a ton of research on this topic and you know how my system is. Can you tell me why I have so much accumulation of oil/water (coffee looking stuff) in the PCV tube on the driver side, in the breather cap and oil filler neck?
I`m not trying to pirate this thread but I think it`s relative.

 

Its very relative...simply, its an accumulation of oil, water and acids that are in the crankcase.

Now for why you have so much around both cam covers ?????With out knowing any history on your truck I would guess that your truck has more than 35K miles and possibly at some point it may have have had part of the PCV system blocked for some period of time. Sometimes the coffee looking stuff is a sign of a faulty PCV system.

If something was plugged the PCV system will soon fail to function properly. If the crankcase is not adaquately vented, the motor oil will become contaminated and sludge accumulations will begin to form. Internal parts, not protected by the motor oil, will begin to rust and/or corrode due to the water and acids that will become trapped within the crankcase. If the PCV system is not functioning properly, the flow of crankcase vapor into the intake manifold will not be properly metered. This, in turn, will upset the fuel/air mixture for combustion ... worst case senerio for a faulty PCV would be intake and exhaust valves being burned, plus spark plugs may be burned prematurely......


oh...and by the way its also common for a properly functioning PCV system sorry for all the drama.............

Heres my version of the dime mod. I have a dime with the head drilled out of the president, and seperator on the passengers side. On the drivers side i have a 7/16 1/4 inch drive socket. The hole is the same size as the hole in the presidents head.
