Disclosure: Doing this mod is something I did to my truck. I know this worked for my 2005, not sure if there are variations from year to year. I do not guarantee your truck will not spontaneously explode while driving it down the road after doing this mod
Parts needed about $50:
DO NOT buy the breather that is picture below (will cause massive white smoke out the tail pipe from pressuring the crankcase)
3 hose clamps
1 machined aluminum plug for intake hole ("lubbock guy" is a member on here that machines them)
new O-ring for CCV reservoir on valve cover (found mine at autoparts store in variety O-ring kit)
12 feet of 1" inside diameter clear hose from hardware store
Well I decided to the do the CCV reroute, which I highly recommend. I had an oil leak that dripped down from the rear of the passenger side valve cover that I couldn't find which turned out to be a bad CCV reservoir O-ring where the 90 degree fitting on the valve cover plugs in. There was oil everywhere, but I couldn't see it without the intake off. BTW, DO NOT install a breather on the end of the hose as I did initially (see pics with breather below, and DO NOT do that
. It causes too much pressure in the crankcase which in turn makes your truck blow tons of white smoke out the tail pipe! The last pic is how I have it now: I installed the OEM 90 degree fitting (that was on the underside of the intake when I removed the stock routed CCV initially) on the end of the 1 inch tubing.
Steps to follow:
1)Remove the 2 sections of intake tubing closest to the turbo
-While removing the the section closest to the turbo, be careful not to damage the 2 90 degree fittings, you will use them again (1 that plugs into the underside of the intake section and the other 1 that plugs into the valve cover)
2)Remove both 90 degree fittings
-It seems the fitting on the valve cover will come off after rotating 90 degrees from the position it is mounted from the factory, careful not to lose the O-ring in the reservoir (mine was bad and had to be replaced, which i did from a auto-parts store variety O-ring kit)
3)Clean out intake sections and install the machined aluminum plug into the intake where the 90 degree fitting was (mine would not fit initially until i filed out the intake a hair) and install a hose clamp around the rubber piece holding the plug.
4)Reinstall the 1 90 degree fitting onto reservoir located on the valve cover with new or reused O-ring and face the opening toward the driver's side fender.
5) Route 12' of tubing from the reservoir fitting (but don't put on the end of fitting yet, just place it near it) across and underneath the brake fluid reservoir and down to the frame. Continue routing over the fuel lines and over the fuel/water separator housing. I ended mine with a dip in the tubing to see if oil will collect and them up towards the front of the fuel tank. This is all inside or around the driver's side frame rail. You will probably have to cut some excess tubing to route this tubing like i did.
6) Now install end of tubing and tighten hose clamp over the 90 degree fitting that comes out of the reservoir (opening facing driver's side fender). Make sure that the tubing is not putting pressure on that fitting to where the fitting can pop off or cause a leak. Also, when tightening the hose clamp over the hose on the fitting, make sure the hex head that tightens the clamp faces straight up and is oriented on the back side of the tubing so it will not rub on the stock intake tubing when reinstalled.
7) Make sure hose is routed without any kinks and interference with hot or moving parts.
8) Zip tie hose in place in various locations (not to moving or hot parts) starting from the fitting going down the frame (to ensure no pressure is placed on that fitting)
9) Route the end of the tubing in front of the fuel tank and cut according to fit.
10) Install the 90 degree fitting that was initially in the intake onto the end of the hose facing down and secure with hose clamp.
11) Reinstall both sections of intake tubing to the turbo and filter.
12) Start truck and ensure nothing is interfering with the new setup. DONE!
