Navistar shop foreman said that they're located on the rear of the isx and that could be the problem that I have with no boost. Said it wouldn't throw any codes, you wouldn't hear any boost leaks from them. I was wondering if any other drivers might have had any issues with this before, or am I just chasing another big pay day for international. The only way to get to them is taking out the doghouse.

If the flex joints in the EGR piping that goes back around behind the engine is/are leaking, there will be soot buildup wherever it is leaking. Look to see if you are getting soot buildup on those flex joints/pipes.

Low/no boost can be a lot of things, not just those flex joints

I own a prostar...

Also, if you need to get to them, they can be accessed easily enough on a prostar by simply pulling the shifter plate and/or accessing them from the side with the side panel off.
