PCV system? What to do?

[dourtyb]

Hey all,

Need to install some sort of PCV system on the Ty. What is the best method?

1. A breather on the driver's side and a stock PCV valve on the pass side running to the intake tube?
2. Stock setup?
3. Something else?

BTW, I used total seal rings. I thought I read somewhere that these rings had different requirements in the way of PCV configurations. Any ideas?

Thanks

I also have been courious of this. I have a breather on driver side and stock setup on the pass side.

A quick search through the syty.net archives for "PCV's" brought up this http://www.syty.net/phpBB2/viewtopic.php?t=8741&highlight=pcvs topic as well as other's that answer your questions I believe.

Thanks for the heads up. After reading that thread it looks like the best thing to do is:

Breather on Driver's side valve cover.
Both Stock PCV valves on Passenger side. One routed to TB one routed to Air Intake duct infront of Turbo.

The breather provides a source of clean air into the crank case. The PCV valves suck the bad stuff out. One is used when engine is under boost (connected to intake track), one is used when engine is under vac (connected to TB).

Sound right?

Now I just have to find my PCV valve tube. Anyone have any suggestions on what to use if I can't find it? I can't find a GM part # for it.

I need the tube that holds the 2 valves, not the valves themselves. Anyone?

Thanks,

Hey regarding the PCV system, I took off my stock airbox and put a K&N cone filter on the end of the crossover tube, and put a K&N breather on the end of the hose coming off the driver's valve cover. At the Wisconsin emissions the lady said my truck was smogging extremely clean but the K&N cone filter was illegal and she failed me because of it, and now I have to put a stock airbox on and show the manager of the emissions test station.

Is what she said true? I think that is a bunch of shit, my truck already proved to be quite clean and it's not like I have the oil draining on the ground or something. Anyone have comments on this? I would hate to have to put the stock airbox back on every 2 years and redo my whole intake setup. Thanks.

Show her the 50 state emission legal sticker that came with the K&N filter. Did you fail because of the air filter or breather filter, or both?

For expert PCV info - search my old posts for a thorough explanation of how it works and how you can modify it.

This is a good example of a perfect understanding.

Well, GM discontinued the PCV pipe that the 2 PCV valves sit in. Since I can't find mine I guess I'll be making one. Shouldn't be too bad. Just need a T that fits into the valve cover grommet and some hose of the right diameter. FYI......

I have that pipe send me 20 and I'll send you one. 8)
