Volvo truck vnl boost leak check
pressurizeing the boost system to find leaks with soapy water and regulated shop air, using a home made tool. air must be regulated 10-15psi (if to much pressure is applied the tool can be blown out and can damage truck or injure you). When applying air pressure with the air regulator start from zero and work up. watch the turbo inlet elbow depending on how your engine stopped and what valves are open that will change amount of pressure needed.
Safety first engine off. Parking break applied.
checking and fixing boost leaks will help with increasing fuel economy and engine reliability.
also will help with preventing dpf from plugging up excessively. dpf should be cleaned right at 220-250k miles. if possible avoid baking dpf filter that will help the filter last longer

This is the best video I've found to run this test. Now, to build that tester. My leak came on all of a sudden, and I can hear it clearly on acceleration and deceleration in the cab. Surprisingly, not a big loss of power and no loss in fuel mileage.
Very useful videos. Keep on doing them 👍👍👍
Thank you sir really helpful video 👍🏼
Huge help! Thank you!
Nice Video! Very informative! Thank you!
hey i have a 2007 volvo d670 10 speed D13 ENGINE my truck set about 2 years and my truck was running good when i originally park it....and it has about 1/2 tank of fuel in it ..so i got ready to start the truck up after 2 years of sitting and got some new batteries in it and it started right up idling beautiful i go to drive it and its if i dont have no power it takes along time to get to 50mph and i have the gas pedal to the floor ..i changed the two filters and put some additive in it i put howes and lucas injector cleaner and fuel conditioner in i went back out to test drive it .and it seemed to be alittle better i was able to get 60 mph but it still taking along time to get there i drove about 90 miles.but it still doing the same thing it is not smoking it but it is actually running good but i dont have no power...there is no code lights on..do you think i need to put somemore additive in it and drive it more..

Haha. I hope you joking about the 120psi. Truck normally operates at 30-45 psi 10 to 15 psi is more than enough. When applying air pressure with the air regulator start from zero and work up. watch the turbo inlet elbow depending on how your engine stopped and what valves are open that will change amount of pressure needed.
