EGR Questions

[tj'sstroke]

I am new to this game and have bought a 2004 PSD with 123,000 miles. I have a coolant leak coming from a blue hose under my turbo. Was wondering while I had the turbo off to replace should I do anything further. Was also wondering about the difference between the EGR block off and the EGR bypass. Which should be used if any. Thanks in advance.

Modifing the EGR up-pipe= EGR block-off removes the flow of exhaust to the EGR cooler and EGR valve. You may get a CEL.

Deleting the EGR cooler= EGR bypass will remove the EGR cooler entirely and you will need to block the EGR up-pipe. You may get a CEL.

Thank's Heavyassault for that explanation. Do you recommend either of these to be done. I bought the truck second hand and had the dealer pull the warranty history. During that period it only had one injector done and a few recalls. I am trying to be pro-active to catch any problems before they happen so it's not so costly. I had thought about an EGR cooler by pass and the EGR slug. What do you all think?

Well, since you no longer have your factory 100k engine warranty, you can go either route. The EGR Cooler Delete is better since you no longer have to worry about your coolant flowing through the EGR cooler. Whatever you do, don't get the Liberator kit. I would contact Innovative Diesel (a site sponsor) and purchase their kit.

Either one will work well, it's how long can you have the truck down. The modded pipe can be done in a few hours, the whole delete may take longer if you are doing it yourself.

i just had problems with that same blue hose on my truck. it was leaking constantly! you have to do a bit of work to get to the turbo. i did a full egr delete while i was in there. i got the kit from adam at first coast diesel performance. it is the one innovative sells. it is a new manifold and has the egr totally removed. get a new uppipe as well while you have everything off. i am very happy with the kit. adam is on this forum quite a bit. his username is abrannan19 hit him up and he will help you out or check out his site. they are great guys over there. hope that helps
