zero affects on A/F if all 3 lines are plugged......not introducing air after the MAF.

your truck looks good

 

Thanks RED.

 

Thanks Red. You guys have some good finished pics. Did either of you take pics during the install? If so, would you be willing to post them so I can see it step by step. I just want to make sure I don't miss a line where air can get in unmetered.

 

I'll take some more and post them when I get a chance.

 

I can't thank you enough.

 

Almightywad, here is a pic of the rear of my plenum ( note the rubber plug installed). Just beside the plugged plenum I set the original line in the pic. with the tee for reference (with the insulation removed)....if you follow the PCV valve in the center of you passenger side cam cover up you cant miss....

Also, notice the bolt head I used to plug the line that goes to the rear of the intake galley.





here is a pic. of the tube from the center of the drivers side cam cover to the bottom of the rubber intake boot as I described earlier.....
I placed the line on top of the boot so you can see where it goes.... .you can leave the line in place and just plug the end at the cam cover and install a breather.( the line in the pic has a plug on it). I chose to plug at the boot and remove the line but it dose not matter.




you can buy PCV plugs for a few bucks off the rack at O'rielys or autozone....


So three points to plug.

1. rubber intake boot
2. rear of plenum
3. line to rear of intake galley

breather on each cam cover and I added one to the oil filler, which was recommended by a tuner.

 

I ordered my Ford Racing Screw in breather for my oil filler today and will be getting it Wednesday.

Nice pics RED.

 

Thank you both very much. This mod not only resolves a problem but it looks good too. Again, thanks.

 

I was under the impression that the engines need a little air flow through the crankcase under boost for dirty air scavenging. This mod is similar to the dime mod or the functioning pcv valve mod. Now there is NO air getting into the crankcase for scavenging, right? I am not pricking out here, just stating something I read in a HUGE post/debate a few months ago. If this is a good mod, with no ill side effects, then I am all for it.

 

That's what the breather/filter is for, to allow the engine to "breathe" and filter any air that might enter.

 

good question Grimace
I think I read the debate.......anyway it was ridiculous....

There are some facts that consistantly get overlooked concerning the PCV system.

1. PCV system is not designed to improve scavenging....only to improve the quality of air .....which with todays high tolerance modern engines is very debatable. Do you want to breathe it before or after its burned in the cylinders ?????
2. PCV was forced on engines.... car companies are forced to put this system on thier vehicles as of 1977 emmissions laws. unfortunately any vehicle that likes to suck air into the cylinders to run will also suck a little oil laden air, if the crankcase is part of you air intake system.

your intake consist of a fliter, maf, crankcase, rubber boot, T/B, plenum, SC, intake galley.

my intake consist of a fliter, maf, rubber boot, T/B, plenum, SC, intake galley.

3. crankcase scavenging...is what we all try to avoid in our intake with dime mods, separators and PCV kits... all agree that intake vacuum will suck air and whatever else out of your crankcase but a simple vent in our modern engine will be just fine.

4. race motors, pre 1977 motors, breathe just fine with crankcase breathers. If you have concerns have your oil sent out for analysis... you might find contaminates if you change your oil every 10K or you might find contaminates when your engine sees around 150K miles ...

5. a top blown / turbo builder recommends breathers and had a pair on his street mustang I watch go 8.8 @ 152 last Sat night.......

 

Very informative. That is all I need to know. I will be picking up a set of filters today Thank you.

 

Hey Red ...great info brother!!!

I have one question though........my line from the bottom of the intake boot came out once and the "check engine" light came on. Will plugging the hole on the bottom of the boot and installing the breather cap prevent that from happening?

I'm still under warranty, so I want to be sure I don't have any problems there.

Also, are there any other gains (HP or otherwise) ....other than not having oil sucked into the TB of course.

Thanks -

Mike

 

I would hope the check engine light came on with that disconnected.... ....thats the same as drilling a big hole in your rubber intake boot

.... start your truck and pull that line loose and feel the massive vacuum present...that set off the codes.

Plugging the line is just plugging an opening in your intake track.

the crankcase is just another component in your intake...to remove this component you must remove it completely....removing parts of it is just like opening a hole in you intake after the MAF.


So you must plug the line to the galley
plug the opening to the rear plenum and plug the boot. Now, the intake system is just as closed as it was with the crankcase component involved.

Major benifits from doing this MOD are

1. increased intercooler efficiency....there is alot of power lose due to restricted airflow and thermal efficiency caused buy oil build up in the intercooler.
2. I think its another weapon against detonation. Oil reducing effective octane rating. If I add 100 octane at the track I know I will see the benifits of the actual octane rating.

 

Sounds like a retune is required for such a mod. Are you not stopping a source of extra air to the engine? I'm sure ford has tuned the computer to compensate for this added air and oil.

Does'nt the PCV system flow both ways? How does the blower relieve pressure now? You plugged all the exits. I thought this was one of the reasons Ford installed a 2-way PCV on the passenger side valve cover.
