PCV system HELP

[Tigerhorns]

I am currently running my PCV system PCV valve to atmosphere, and side port to intake, and i am running my BOV into where the PCV valve went, because i am missing the wastegate vacum source on my air intake manifold. There has to be a better way for me to be running this. I just got a PR FMIC when they went on sale about to put it in, and noticed that it didnt have a nipple in the J-pipe, and i don't know where to put my boost controler now either. Someone help me


I only have the FPR, and the big nipple for the PCV valve on my air intake manifold, but it looks like a turbo manifold

The stock 1g intake manifold has spaces for 2-3 vacuum nipples. Are you just missing them/are they plugged? You need to reconnect your PCV the way it was from the factory though.

I'm missing the middle one, and i beleave its for the wastegate. There is no way i can hook it back up to stock i am missing the wastegate nipple on my air intake manifold. I looked all over there isnt another port, and it looks like there never was a port where it normly is '

i don't know where to hook my boost controller up to, and i dont know where to hook the BOV up too if i put the PCV valve back there

I can get you the part number for the nipples on the intake manifold if that would help.

You can tee 1 or 2 things off the FPR vacuum line if need be.

You could easily drill/tap/JB Weld (or properly weld if you aren't cheap like most DSMers) a nipple into your J-pipe before installing it.

Ya i found a place today that told me they would weld it for me. I have the boost guage in the FPR teed in. Should i run the BOV there too?make another tee? Then my PCV system be working properly setup like that?

 

[snowborder714]

No, the bov should never be in a tee setup. You could try putting the MBC on the tee and see how well that works.

 

[Tigerhorns]

and run the bov from where? I'm allmost thinking it would be easier to take the damn air intake manifold off. I have never done this before, but i know i could probly do it before i could figure out how to set this system up right, but honestly that isnt the solution i want ><

 

[snowborder714]

What is wrong with the other port or two that the intake manifold should have? I know you said there is no nipples there - are the threaded holes not there completely, or are they just missing/blocked off?

Maybe you do need to take the intake manifold off to either swap or drill/tap some more holes.

Or just get a vacuum block and run everything off of that.

 

[Tigerhorns]

Ya im looking where the hole should be, and there just never was a hole of any kind there its smooth. I only have 2 nipples FPR, and one for PCV valve, and what is a vacum block?

 

[snowborder714]

Go Google it. It's a metal block with 3-6 ports in it. You connect one port to your intake manifold, and then connect items that need a vacuum source (bov, FPR, MBC, etc.) to it. It basically just gives you more ports without doing anything to your intake manifold.

 

[Tigerhorns]

I googled it right after i asked man that is just badace i wish i would have known about this earlier wow this would have saved me alot of oil shooting out my BOV, and ect . Is there one that fits really good on our car. I know they all would work, but just wondering if you may know of a good one for a DSM

 

[snowborder714]

A vacuum block is a vacuum block. They're a universal part. The only differences you might find are shape, color, number of ports, and size of ports.

 

[Tigerhorns]

now when you say i can run everything off this that is including the pcv valve? because the way it sounds to me it goes into the intake manifold vacum source then powers everything else off those different ports. Then you would cap the other sources off am i right? Sorry to drag this on, but im a newbie

No problem in asking questions. I would not run the PCV through there. The only thing I would ever put in between the PCV and the intake manifold is a check valve and/or a catch can. That is it.

 

[Tigerhorns]

Ok then where would i take the source for the vacum block from? If the PCV valve will be going into that big main port? Thanks for the link im reading it now

 

[snowborder714]

You could take it from the brake booster line.

 

[Tigerhorns]

I don't have coolant lines on my turbo right now it's a 14b do you think i should put some on there?

Allright well i called today to order a vacum block, and i was told that it was a bad idea, and everything would be running crappy, but it would work is this true, or was i trying to be sold a air intake manifold?

 

[snowborder714]

That's a load of BS from whoever you called. It will work just fine.

 

[Tigerhorns]

Well the whole staff was like wow... are you seriouse with wanting this it's gunna make everything run slower, because it's all coming from the same source sucking the life out of it is how it was explained to me.

 

[snowborder714]

As long as you have a large enough line feeding the vacuum block (i.e. brake booster line), you'll be fine. Obviously if you use a small vacuum line to feed it you might have some issues.
