My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made. No rate, site gets it all.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

Check all the rubber boots on the intake. These engines have been having issues with them leaking, the manifolds leaking, and a hose from the intake to the compressor leaking.

If still not able to find, then I suggest having Peterbilt (unless you have the kit) connect the boost tester on the passenger side, charge it with air, and listen for leaks. They are hard to find when the intake is leaking like that without the kit.

they are not the site feedback.

I see you viewed this and this is still showing as a open question due to no positive (3 stars or more) rating.

Did you still need assistance with this?
