There has been some talk lately about how to set up your pcv system, as you already know it cant be left "stock" and just running a line from your stock pcv to your turbo inlet just doesnt cut it. If done either of these ways your crankcase will be pressurized either in boost if left stock (very bad), or in vaccum if just ran to turbo (bad). I believe this is also the cause of many "my turbo/motor is blown" threads because your car is smoking like chief sitting bull with his peace pipe.


This is what I used you can use different sized hose if you like.

I got most of this at Advance Auto Parts, but any part store will do, you might have to dig a little for some good pcv valves.

1. 3/8in. fuel line hose, I bought 6 ft but you will only use 4-5. $1.50 ft.
2. 2 PCV valves puralator PN#PV1029 (these are good ones and will not leak boost) $4.00 a peice
3. 12 3/8in. hose clamps (I got a few extra) $5.00
4. 1 3/8 threaded hose fitting $1.00
5. 2 3/8 plastiv "T" vacuum fittings $1.00 a piece
6. 1 Home depot oil catch can, (air compressor filter) and 2 more 3/8 hose fittings $15.00

That should do it for a total of around $30.

Step 1.
Take your old pcv valve and hose to the manifold, you can throw out the old hose since you wont be needing it. If you have the stock valve still the elbow should come off the top, pull it off, if not you can cut the elbow off.


Step 2.
Open up your pcv valve and take out the inner slide and spring, you can toss the slide and spring also, all you need is the valve body. Put this back together


Step 3. (optional)
I drilled the holes in the top and the bottom of the valve body bigger for some better vacuum action.


Step 4.
Now your "gutted" stock pcv valve is finished, set it aside for now and find a place for your 3/8in hose fitting to go into the intake of the turbocharger. I put mine in the end of my cone filter, this is a good spot, if you dont have a filter you should look into investing in one, it will make your turbo and motor happy.


Step 5.
I used one of my "T" fittings right off of my intake manifold, one side is going to my BOV and boost guage, if you dont have anything else using this vacuum sorce you dont need a "T". The hose connected to the otherside of the "T" needs to be assembled in this order. First it goes to one of your new PCV valves, the direction of airflow through this valve should be going towards the intake manifold. I have another length of hose connected to it, and from there it goes to the other plastic "T" fitting. Use clamps on all fittings, since it could leak vacuum/boost.


Step 6.
From this "T" one line will go derectly to your gutted stock valve placed in its "stock" position.


Step 7.
The other side of the remaining "T" goes to your Home Depot catch can, the catch can can also be placed in line between your gutted stock pcv and the "T" from step 6. After the catch can I placed my second "new" pcv valve. its direction of airflow should be aiming towards the air filter, so when your boosting the intake of the turbo will vent the crankcase.


put the filter back on the turbo and you should be ready for some rippers, Now your crancase will be in vacuum if you are in boost or vac. If your car is burning oil I advise you to try this first since it is cheeper than going out and buying a new turbo or motor.

Here is a pic of the final product.


If any of the pictures are unclear or you have any questions you need to go back to school because its really simple, I think a gay monkey could figure it out.

Thanks i didn't feel like going behind the block to get this done. Good write-up

Scott-EP

i had plans of doing the exact same thing. im glad to know it works w/o me putting out the effort 1st

So pretty much if you have a turbo, PCV valve is sort of a must?

Some just vent it from the back of the block to the ground, I hear it also works, just makes me feel better doing a setup like this. If you have a turbo you have to do somthing, you cant just leave it stock.

onlyflash944

sounds good. this is a very helpful writeup that i will be using soon

Tink2150

Yes very helpfull indeed. i was going to be looking for info on this in a couple weeks anyway...

rsmith2786

Were you saying that it was bad to have vacuum in the crankcase?

Why did you post this crap up again?

Why would you want inconsistent blow-by vapors going back into your motor and messing up the A/F ratio?

Why would do this much work for worse results?



SIMPLE SOLUTION: VENT THE VALVE COVER AND THE STOCK CATCHCAN TO THE GROUND

Hey I was asked to put it back up so stop being a ------.
