Kolehamilton Posted April 11 Share Posted April 11 I have a 2013 Mack Cxu613 MP8, It has a holset turbo, The V Band clamp broke, installed a New one. It’s not building boost. there was no noise when the old clamp broke, it just lost boost. I am going to take the new clamp off and clean any corrosion and make sure everything is straight. then take intake hose off and try and turn turbine with engine off to see if it turns. just seeing if anyone else had any insights or suggestions. 1 Quote Link to comment Share on other sites More sharing options...

The Heinz Posted April 11 Share Posted April 11 Just a parts guy, but the oring for the compressor side could be pinched. We also see the CAC hot side pipe going into the turbo fail all the time, we usually replace the boots and clamps with spring loaded types. I only saw this once, but the CAC cold pipe going into the throttle valve had cracked somehow and was causing a decent boost leak. Quote Link to comment Share on other sites More sharing options...
The Rubber Duck 006 Posted April 12 Share Posted April 12 I had an Mp8 DO the same thing and broke the same clamp. Turned out that the Turbo was locked up as well. 1 Quote Link to comment Share on other sites More sharing options...
