Volvo d12 air leak sound from egr

What was the solution to this problem I am experiencing the same thing

 

Use a water and soap, also boost leak tester from otr performance will help. I have an issue on pipes, it was a small hole on welding. I bought a new pipes for 57$ and change it. Also this increased my boost for 0,5psi. Now it's 34,5 on full throttle in uphill with 40+k lbs loads.

 

Ok just had something happen on plastic hose feeding into turbo there is a little airline that is covered with corrugated plastic looks like electrical wire mine was completely vibrated out but yours may be loose on passenger side dah,almost same level top of motor valve cover T/A guy said he couldn't do anything but had me push fuel pedal boom saw exactly where it was reinserted tightened 68 bucks plus 30 I gave tech IT CAN AND WILL DAMAGE TURBO ETC.D13 gd motor strong got 1 million six hundred thousand out of last 1
