Driving an 07 KW T600 with a C13 Cat motor. Noticed the turbos sounding different, and loss of power. Sounds like it's overspooling, Humming/whining, kinda sounds like a belt driven blower on a hot rod. Don't have a boost gauge or a pyro, so I don't know what I'm getting for boost. Had it at a local shop, turbos , hoses/clamps, CAC apparently checked out ok, Anyone ever had this issue?

Could be a bad intake elbow gasket. Did they check for shaft play on the turbos?
-
How many miles are on the turbos? Specially the smaller one.
Is it low on power when warming up? Do the turbos sound like they are on a different page?
I have simular things going on when cold and couldn't get it solved in almost 5 years. Even new turbos didn't solve it. They were due and made some funny noise. If I remember correctly the small one was at 1.2 million km and the big one at 1.9. -
Before you blow anything, I'd bring it to CAT in Winnipeg. Talk to Randy. Or give him a call. I had my engine rebuilt from them and they're awesome and stand behind their product/workmanship.

Make sure the plumbing (bellows) isn't cracked or split....also pay attention to air compressor intake air plumbing.
