Boost leak!
Was driving today and boom, hissing. Wasn't even under load, just around town. Suddenly, pop, it went hiss. At first it was only under load, then all the time. Something definitely broke. Managed to get it home, pulled both tubes on either side of the intercooler and both checked out perfect. cleaned and reseated everythinig, and still the leak remained. I'm fairly certain it's at the intercooler at this point. I could hear a slight hiss at idle, when i shut it down the remaining pressure hissed out from waht felt like the front.
For sanity's sake, I'm thinking intercooler. both sides are flawless.

I was thinking of going the CFS route as well. For $200 you can't go wrong with their reputation. When I shut the engine off, there was a definite release of pressure. It's totally gutless now, the engine is not getting any boost. When I put my head down by the front grill I can hear a blowing noise that is not normal.
I'm going to pull the intercooler friday to check, if it's blown are there any visual indicators. I saw that the inlet was metal but the outlet was plastic, so I'm thinking it may be something with that.

I got mine from Rockauto I believe. 11k on it no issues. If you do that I’d strongly consider a CCV reroute or CCV to catch can/coalescing filter then back into the intake. It’s so much better for your engine to keep that oil vapor out of the turbo, CAC tubes, intercooler and intake.

That was another thing, there was definitely oil inside the tubes. Not a lot, maybe a half a teaspoon pooling at the bottom of the boot, plus a coating on the inside of the pipes. I'll look into the ccv reroute, that's on the intake before the turbo right? Is it bad for the turbo? I always thought a bit of oil coating was a good thing in most cases.

It’s another ******* design idea to save the environment. Your intake should only ingest air, hot oil vapor is just going to coat everything on the intake system with crap. I ran a 1” heater hose from the CCV fitting, down the frame rail and terminated by the transfer case. I replaced my entire intake system except for the CAC tubes which I cleaned out and had powdercoated oh and the intake manifold which I removed and ckeaned.. No way was I putting that nastiness back into the intake. My turbo vanes and whole intake system are dry as a bone and VERY clean after 11,000 miles.
I work in the oil and gas industry and see hundreds of CAT natural gas compressors and diesel engines and every single one of them has the crank case vented to atmoshphere. The turbo has it’s own lubrication system. Our turbos have a feed tube that pulls oil from the oil cooler to keep the internals lubed. That’s all it needs!

It's listed as incompatible with my 6.0 excursion, but i'm fairly certain that it'll fit, being that it fits the f250. Is there any reason this intercooler would not be compatible with my excursion?

Bump! Any idea why the intercooler wouldn't be listed as compatible with the excursion but would with the f250?
Edit: Nevermind, it sold out.
Between these two:

Are they the same? or is one worth the extra $50?
