I found a massive air leak where the charge air comes into the inlet side of turbo- There's a 3-4 inch adaptor pipe that is wiggling around, and when the truck is at 1400rpm , massive amounts of air is blowing out.
Is this solvable with o rings?

what year is it?
charge air doesn't normally go to the inlet side of the turbo unless you have a newer model truck with the d11,13, or 16. they have a discharge recirculation valve on the charge air tube that feeds charge air back into the inlet of the turbo. however, volvo now has an ecm reprogramming recall that now disables this device since it's worthless...just like volvo's engines.

Ok...so chalk this up to another learning experience(=:biggreen$
I would have sworn that the direction of air flow was from the charge air tube coming into the cold side(front-towards cac,away from exhaust) of turbo.
This has also been my problem in trying to determine how blocking off the crossover tube with a pipe plug works.
I was always under the assumption that to get the proper boost, that intake air would be utilized and compressed by the turbo, then immmediatley enter the combustion chmaber. But what I learned last night is that the compressed air then goes to the CAC first from the bottom of CAC, then comes out the top , and then into chamber.
:wearsduncecap:
Ok, so the o-rings i had replaced at the TA ontario east were from the adaptor that connects the turbo cold side to the cac pipe(front end). 1.75 hours labor and $5.80 in parts.
running now, much better.
the adventure continues
