...just discontinued (by passed with the downpipe) Blocked off the EGR cooler and left it in place? If the hot exhaust is no longer going through the EGR but the coolant still is why would this not be acceptable? or maybe it is? Or am I missing something altogether?

...would someone in the know please explain..even if it IS a stupid question. Thanks

 

You'll get an EGR code that you'll need to turn off with a tuner, but it's doable. You'll also have to cap off the exhaust end of the EGR cooler. Search stealth delete.

 

not a stupid question. Blocking off the EGR cooler and leaving it in place is perfectly acceptable and even a preferred method. With the Delete kits there is a history of the Y pipe cracking after approx 15000 mi without the support of the EGR cooler. A write up on this that can be found at FICMrepair.com
Ed would be happy to explain this to you as it happened to him.
here is a good video about EGR deletes from PowerstrokeHelp:

 

As a follow up to my previous post I wanted to mention that I went with the IPR Gen 2 delete knowing full well that I would have to replace my Y-pipe with an aftermarket that has the flex tubing when mine cracks (I did say when and not if).
I would have preferred having the EGR welded shut but under the circumstances my truck was down for an oil cooler R/R and could get the EGR delete installed for free at same time. I'm just hoping the Y-pipe holds up for long time.

 

Thanks for the video link.....I like the stealth delete as well as anything I've seen. That being said, the guy in video lost me when he said the puck in the up-pipe and leaving it connected to the EGR cooler was a bad Idea but welding it shut, hooking everything back up and leaving the EGR cooler in place was a good idea? Either way the up-pipe is supported by the EGR cooler connection so that confused me. My thoughts on this is that by using the puck to block the EGR cooler you don't have to tear down the top of the engine to eliminate the hot gases from cracking the cooler. It seems like a no brainer??? But again I'm probably missing something.

 

Thanks for that info.

 

I wondered about the same thing. The only thing i could think was that a plate between the up pipe and egr cooler caused extra stress on the y pipe where as welding the egr cooler closed left everything as was.
Btw, I've read that some folks pounded a freeze plug into the egr cooler rather then welding it.

 

Possible...but I wouldn't have thought that the tolerance in that area would be that precise.....I've heard the freeze plug burns out relatively fast necessitating a re-do.....I don't like re-do's.
