Advantages are simple. Stop running used exhaust gasses though the engine and stop running blowby through the turbo :eek: . I was a little shocked to see the amount of oil dripping from the bottom of the intercooler. Truck only has 45k miles. I thought, for some stupid reason, that the pcv flow couldnt possibly be that heavy. Just think, all that oil going through the turbo and the intercooler, gumming it up and reducing efficiency....

If you don't reroute your PCV, there's a very good chance you'll blow the IC boots off sometime when you're romping on it - maybe even just trying to climb a hill with a load. Engine spools up faster, runs cooler, and runs cleaner. If you're still not convinced, try searching around and you can see some pics of what the intake looks like with all of the soot caked onto the interior - some have reported as much as 1/4" of the crap caked in their intake.

After rerouted my PCV i didn't notice anything right away, but after towing my 30' toy hauler on a sixteen hour drive i noteced better milage and power. I think maybe it is because it cleaned out the intercooler, :thumb:

I blew an IC boot off pulling my 5er through Cali. I could not get it to stay back on because of all the oil, it was everywhere. I had to get a new boot and it has been fine, but I haven't pulled in those kinds of temps yet. I don't know how you guys survive when it is above 80 deg outside. Of course I haven't found time to route my pcv yet...soon I will.

Yeah, reroute it soon. I blew one of my IC boots off not a month after I bought the truck (used). Scared the hell out of me. Truck wouldn't go for anything (I was on I-80 at the time), and was smoking like a chimney. If I had passed a cop, he would have had to pull me over because no one behind me could see. There was a Fed Ex box van behind me about 75 yards, and I didn't even know he was there until he pulled onto an exit and he was out of my smoke screen.

Just did the PCV today. Tony, your kit is by far the best thing going. I did it a little bit different than most, just to see if there is a change in the way she runs now. Going to chek it out for the next month and see what the changes are in performance. I do a lot of city and highway driving, empty and towing. I have good stats on before the mod through the PDA. Did find a bit of "gunk" in the metal lines as well as the inlet to the turbo. Cleaned everything up, only time will tell. Yardstick, there are plenty of places that I have read on this and other sites, and a large majority say this is a useful mod.

I'm REALLY interested to know if the blocker plate mod will impact my required yearly emissions test I need for registration. I can't tell you how much I dislike this emissions testing BS.

Either make the plate with a tab for easy removal, or buy one with a tab for easy removal. Then... when it comes to testing time, just take 5 minutes at home and remove it, tighten it all back up, and go get tested.

This is precisely why I blocked mine but decided to leave the EGR plugged in - in the hopes that if I am ever required to test I will be able to remove the plate and the EGR valve will still be opening and closing per spec. If you disconnect it and leave it disconnected, you're more likely (my thinking) to wind up with a non-functional EGR valve.

Thank goodness that Kentucky doesn't currently have inspections... ;) (though I understand Louisville might :rolleyes:)
