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.

You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see,

touch, smell, hear the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

Once an answer is provided, you should see a rating screen. Please rate my personal service to you. The ratings are my personal feedback,

they are not the site feedback.

Thank you for allowing me to assist you through Just Answer!
