I'm using this http://lightning-enterprise.com/pcv.html
and I'm not convinced it's even slowed down the oil into the throttle body. I was trying to avoid those oil separators as they seem like a PITA to constantly keep up with.

Any better fixes?

I'm about to disconnect the hoses plumbing the oil into the intake.

 

I use that same kit and no oil in the boot or the t-body. I installed the kit at 300 miles and it now has 11,500. Call them, maybe you have a defective part.

 

I tried that kit too but it didn't work all that well. The only thing that has worked (haven't tried the seperator yet) is removing the pcv line on the pass side that runs up to the upper intake behind the idle control valve and installing a dime to keep it from sucking up any oil. I then used a regular 5.0 mustang pcv valve to replace my stock pcv valve and I have had ZERO oil in the boot and in my intercooler. When I removed the intercooler, I had nearly no oil left and I no longer had the small puff of smoke on start up.

Only cost me a pcv valve and a dime

There are some write ups on the dime trick. You may want to do a search.

 

I put breathers on both cam covers, and replaced the oil filler cap with a breather. There is now no way for the oil to be sucked into the TB or plenum.

 

I agree with ShockTherapy. Check out this thread Blown:

By the way ShockTherapy that pic of your beast is absolutely
B E A utiful!!!

 

but doesn't that allow unmetered air to enter, I thought that wasn't good.

 

Here is a SIMPLE & CONDENSED version of what you need to do.

1) Add Breathers to each valve cover,

2)Disconnect and/or plug anything that has to do with the factory PCV system.

 

he forgot to add that he pluged the hole in the rubber intake boot and pluged the rear of the plenum and the line that goes to the lower galley.


you are correct, if you just add breathers to the PCV system you will be allowing unmetered air into you engine., the closed PCV system is a component of your intake system....opening it to the atmosphere with a breather would be the same as drilling a hole in your plenum or rubber intake boot.....aka.....allowing air to enter your engine that has not passed over your 90 MM MAF.

this is one component of the intake system that is in place because the law puts it there... emissions....its not a cleaver ingenious method engineers derived for better ring seal.
I removed the PCV because I dont want crankcase gases and oil vapor in my combustion chamber...but to each his own.

I just went by the local Shell station for my state inspection ...they raised the hood to ogle at my supercharged motor(3 mechanics) and said nothing about the 3 breathers staring back at them....

 

There really are no drawbacks from doing the breathers unless you start to get blowby past the rings. What will happen then is you will start to get oil accumulation around the breathers. I have installed the breather deal before on some Mustangs that were supercharged.

The best way to keep the pcv system operational and not have any oil drawn up through the throttle body or intercooler would be to block the top line pass side to the plenum (dime trick), leave the drivers side alone, remove the restriction in the line running to the lower galley the runs to the pcv and install a regualr 5.0 pcv valve. What would happen is in regular driving, you would get normal pcv operation and when you got into boost, the pcv valve will keep the pressure from the galley line from going into the crankcase and any crankcase pressure would be vented through the drivers side into the throttle body.

Currently the lone running from the galley to the pcv is restricted but still pulls a small amount of vacuum. That is how I have it with the upper pcv valve line blocked with a dime. Absolutely zero oil and no oil leaks (which would be an indication of too much crankcase pressure).

The only thing I don't like about the breathers is without SOME kind of fresh air getting drawn into the crankcase (not just vented) is that the oil gets dirtier quicker (at least with the cars I have done it on).

Can you imagine how much oil you would get in the throttle body and intercooler if Ford hadn't had restricted the line running to the galley??

 

of course, if you plug the only outlet path for the PCV system (plenum-dime) you reduce the chance of oil ingestion in the plenum and increase oil ingestion to the lower intake galley !!... why stop there if your going to plug .......just plug the passenger side cam cover.

the PCV systems has two little holes for crankcase ventilation about the size of your pinky and you just reduced that path to one, PCV flow control engineers know the direction of flow via multiple pressure changes, positive and negative vacuum etc.

engineers designed the PCV system vacuum requirements for your supercharged motor which you have just drastically reduced which will only result in incomplete engine ventalation and you know the results of that.


PCV systems have an inlet and an outlet ....you just plugged the outlet.

 

explain how i plugged the outlet??

The line to the galley will not draw anymore oil than a regular passenger car will. It acts as a normal vacuum line to the pcv valve. Most of the oil accumulation comes from the plenum, not the galley line.

 

Same here. I replaced the oil cap with a breather cap, to work in conjunction with the Lightning-Enterprise parts. No more oil problem. Don't fill your oil all the way to the full mark either. Keep it just above the fill mark. About half a quart low.

 

Can anyone provide specific K/N Part Numbers for the two cam cover breathers? And then there is the part number for the oil fill breather. P/N? Does it screw on like the stock cap?

Thanks so MUCH!

 

Thats what I did.

 

explination,
In reference to crankcase ventilation the rear of the plenum is considered the PCV outlet....you put a dime in the line at the rear of the plenum..., didnt you ? thats a plug.
