When I put the stethoscope up to the back of the valve covers I could hear the air really well in both banks but it was a little louder in the right (not by much, but noticeable). Since it should be quiet with the IPR ramped up, I would imagine that a leak would sound greatly different than the air noise heard before the IPR is ramped up, right? If that's the case, I would say that I am having a problem with my IPR. Thanks for the info so far guys, Brandon

Hey guys, don't pick to hard please, if you read my intro you know I just started working on the diesel's and I have a quick question. I got my first "real" job on a 6.0 today. '07 E-350 6.0L, no start when warm. Did the basic testing, pulled codes, came up with a code, but I forget what it was. Followed the TSB for it (only had 300PSI ICP when tested warm), I got everything set up for the air leak test but I did this towards the end of the day and didnt go any further because of not knowing. Now comes the stupid question. When I have the air going into the system, I hear air rushing around, then when I ramp up the IPR the sound changed a little but not much at all. What noise would a HP oil system with no leaks sound with the IPR at 92% (or what ever the max is) sound? Should it be quiet? Does this sound more like an IPR problem to you guys? I just dont know guys, lack of experience here. Thanks in advance, Brandon

Ahahahahaha

The topic is titled "2001 Excursion Issues" Anyway, I could still check out the ICP and IPR, correct?

Keith, this is a 2001 Excursion with a 7.3 not a 6.0, I just wasn't sure if I should have put it in the mods or the 7.3 forum due to the mods, thanks for moving it though. As far as your suggestions go if they would still apply to the 7.3 (I dunno), I would be able to make recordings with either IDS or VDR, but I would probably just use the IDS because the issue is very consistent and very repeatable. Thanks again, Brandon

Hey guys, I'm new here, just had our diesel tech quit and had the work plopped into my lap (with me having no prior experience), yay! Anyway, we've had a relationship with a certain Excursion. The customer need injectors and a turbo at 200,000 miles so they decided to go with a Swamp's setup, not only for the price, but also some fuel economy. The only reason that the customer hasnt been jumping up and down about this truck is the fact that they are getting 25-27mpg now. So here's the problem, the truck runs fine. It just doesnt idle for crap after warm. When pulling up to a stop sign the truck surges, and almost sounds like its missing. Sometimes when your stopped it'll actually surge hard enough that it moves the truck. Like I said, it has aftermarket injectors, turbo, and a tune. I dont think its the tune because we've had about 5 chips in this thing with different tunes on it from Swamps, and finally the chip that is in it now has 6 different tunes trying to find one that doesnt surge, but it still does it on all of them. Just curious if anyone has ran into this before? Thanks in advance, Brandon
