Default Loud Pop under throttle... No boost?

Thinking hose from something inline from CAC or turbo. Sounded like a balloon pop or a gunshot then no boost registered.

I can here at least one of the turbos spooling, whining, but zero registered on the gauge and no power while EGT shot up.

About to go out and look. Any typical points of fail on the 6.4 I should be looking first?

Thanks guys and Happy Easter!

Definitely sounds like you blew an IC pipe off to me.

I'm not real familiar with 6.4 but when that happens on my 6.0 it's one of my turbo boots. You probably need to take it off clean it then borrow your wife's hairspray. Make sure there is no oil on it then give it a light coat of hairspray (end of the tube) then reattach after about 30-45 seconds. Make sure you don't over torque just in case some of your tubes are plastic they will crack.

Yep... Bottom of CAC.
Torqued it down. Still blowing off under minimal boost ~20 lbs.
Any reason for this? Could there be a blockage anywhere preventing passage?

It was quite oily... Cleaned inside of boot with rag and the piping. Mishimoto CAC.
I just want to make sure there isn't anything mechanical or some sort of blockage I need to check before I go purchase a beefy clamp to remedy this. The clamp on there is new that came with kit I believe but it is as tight as can go as isn't doing the job.

Pull the boot and pipe off and clean very well. Could even spray some hairspray on both then reinstall and torque down tight. I had the same thing happen to me. I did end up getting a longer boot though.

look at the end of the ic pipe. eventually the end will start to "cave in" slightly. this is either caused by time, or tightening the clamps to tight.

you can take a pair of pliers and bend the end of the pipe back out. i bent mine slightly farther out than straight to kinda simulate a bead rolled end of the pipe.

take boot completely off. wipe out all oil. wipe end of pipe out, and off. take carb cleaner spray end of pipe, wipe off. spray inside of boot. wipe out.

take your wifes hairspray and spray end of pipe. reinstall boot, and tighten clamp. let it sit for 15-20 mins.

drive, be happy.

the hairspray acts like glue to greatly assist the clamps to hold the boots on. but yet, will let you still take the boots off if needed.

nothing will work, unless you check to make sure the end of your pipe is not starting to collapse. this is normal with time, simply bend it back out, its just one of those things you need to check now that you had a issue.

Most likely have to get a new boot., the oil starts to break down the inside layer of the boot. Good way to rid of the oil is a CCV mod
