Need 6.4 assistance ASAP!?

[08Monster]

I was driving in my new 2008 6.4, and it was over boosting bad. Around 25-30psi at 50mph. So I hit it down a little and pegged out the boost at 40, and I heard a loud pop. Popped the hood and the CAC tube blew off. No big deal. Oil everywhere though from the tube? Is that normal? Was that causing my whole issue? What to check? Thanks, I'm on the side of the road and need help ASAP

the overboost could be caused by a bad or plugged ebp sensor located on the drivers side upipe.

the oil in the tube is from the turbo bearings letting oil by. it means the turbos are getting worn out. pull off your air intake and check shaft play.

I'm a noob to this so I'm gonna need a little more info. I just bought the truck yesterday

I wouldn't raise the alarm on the oil in the hot side pipe just yet. Your CCV dumps into the intake before the turbos and there will be a build up over time. If you are worried about the turbo seals going, check the down pipe at the ball socket just before the cat.

Again, can you shed a little more light?? Haha I don't know most of these terms. Sorry

CCV=Crank case vent. Its the small 1" tube that goes from the oil catch can (on the passenger side valve cover) to the air filter/intake tube. Down pipe=The large pipe at the back of the turbo that runs down the passenger side fire wall. There is a ball and socket joint at the bottom of the down pipe and just before the large cat/DPF portion of the exhaust pipe.

when my atmo turbo bearings went, nothing went down the downpipe-it filled the intercooler.

Better. But for now, just put that tube on so at least I get some boost, and figure the rest out when its not -15?? Is the EBP sensor on the driver or passenger side of the block, and the tube they are talking, its that little skinny tube attached to it I'm guessing? So I can clean those

Also, it has turbo back exhaust if that makes a difference. Turbo back, Spartan tuner, afe intake, egr delete

Start simple and go from there. No need to get his stressed out after just getting the truck. If its the turbos, so be it.

EBP tube is on the driversider up pipe where it ties into the egr coolers. They are prone to freeze up when it gets cold. Cleaning it is a 5min job.

 

[08Monster]

If you know what your looking for that is. Is the part I need to clean obvious to see?

Its the only 3/8 hard line the comes up from the up pipe. The sensor is located directly under the fuel cooler. Easy breezy

Nice!!! If this fixes it that easy, I'll be happy and send you a beer. Haha

Get a new boot when you can. Once they slip off, they come off much easier the next time.

 

[08Monster]

I put the hot side boot back on, and its fixed? Haha no over boosting, lots of power again.

Circled in blue is the CCV hose

You can either add some rubber hose and dump to ground and get a fancy kit like I did from Maryland Performance Diesel to add some looks

This is how my pipe looked when I took it off turbos were fine.
