Where can I get the 4" x 3.5" Piece of steel tubing?
Can I use PVC instead or is it not strong enough?
Thanks.

A 4"x3.5" piece of pipe for the CCV mod? When I modded mine, all I did was run a 10' piece of 3/4" ID heater hose from the elbow on the factory CCV cover down along the firewall, and then routed it down the driver's side frame rail. When it hit a convenient point (just forward of the T-case skidplate), I zip-tied it so that the end of it pointed down and cut the hose off ~3/4" below the bottom of the framerail. Then, I went back and secured the hose in place and it's worked fine since.

Total cost: $8.90 for the hose (10' at $0.89/foot) plus $0.99 for two hose clamps (I double-clamped the hose onto the factory elbow just to be safe) = $9.89

I didn't want to pay ~$45 for the IH CCV tube, plus installing it looked to be a NIGHTMARE (not difficult, but VERY tight access between the back of the engine and the firewall), so my <$10 mod seems like quite a good deal.

PVC will be fine, the inner diameter will be marginally smaller than steel tubing. But after having the ccv restriction removed you'll still be ahead airflow wise. I believw what you are looking for is PVC repair coupling w/ and OD of 4". Can't remeber if the ID is 3" or 3.5" though.

Go by any local muffler shop and ask if they have a scrap piece of 4"OD about 3.5" long.....I did this at a buddies shop and he had a piece of stainless steel laying around and gave it to me free. Oh if you get a piece of raw metal do what the other guys have done and get some flat black paint and spray it.:cowboy:

Oh, are you using the piece of big pipe to replace the piece of tubing the CCV dumps into? If so, how do you deal with that green solenoid tubing that also goes into that piece of intake tubing?

The intake tract is 2 hose pieces divided by the CCV. The Exhaust tubing is replacing the part of the CCV piece that bolts to a bracket in the middle. The green tube goes in the hose between the CCV and the turbo compressor housing.

Did you plug the intake tract where the valvecover part vented in?

What did you plug the hole with???

The hole left by disconnecting the ccv tube from the i/c system is after the air filter and under vacuum. It must be sealed off to prevent dust and dirt from entering the engine.

The metal tube eliminates the need to plug a hole.

Installing that 3.5" x 4" tubing in place of the stock CCV piece will allow about 10-15% airflow space gain :sweet

Cool--I'll have to give that a try. Did you just poke a hole with a nail or some other sharp instrument to stick the green tube into?

Yes, I plugged the hole in the intake tract as soon as I relocated the CCV.

When I had my old CCV relocation kit from ITP (old enough that when I called Dennis ~1 1/2 weeks ago, he said "You're still using one of those? Geez, we quit selling them a couple of years ago") it came with a rubber cap to fit over the CCV inlet. It still held well, so I kept using it but I'll have to try putting in a new piece of ductwork.
