While traveling to Illinois I noticed a different sound coming from the engine. I opened the back hatch and did a visual inspection and did not find anything out of place. We left headi g to Nashville. After archiving I pulled the bedroom engine hatch to find the turbo disconnected from the exhaust. There was no change in the performance or excessive fuel used. There was no damage from the exhaust. I was able to repair the the connection using the same clamp. Pulling out tomorrow headi g to Asheville through the mountains. Hopefully there will not be any issues

Odd there was no change in performance or fuel consumption. Did you determine the cause of the loose clamp?

You shouldn't have been able to drive more than 10 or 15 mph if the turbo was disconnected.

Unless the Marmon Clamp between the Exhaust Brake and the Turbo Outlet or, the Exhaust Brake and the Exhaust Pipe is the one that came off. In this case, it would be noisy just like the OP described with zero effect to performance.

I would keep a close eye on that clamp. Are you sure the lip on the exhaust pipe is still there? These clamps usually don't come loose. At 1000+ Deg F, An exhaust leak off the Turbo could cause a fire.

I had that happen on my coach. It was not a clamp situation. I had to actually have it welded back together. I had a decent amount of soot deposits on the bottom of my bed...

On the other side, the intake, my mechanic forgot to connect the rubber tube from the intake to the turbo after replacing the head gasket....result....could only go 30 mph.

Never expect they will do everything correct.....LOOK with your own eyes for possible reassembly errors. These guys are not perfect by any stretch.

It was the clamp holding the exhaust to the turbo. No performance changes just a different sound from the engine when going to second gear. I'm leaving this morning heading to Asheville through the mountains. I will keep a close watch to ensure the. Clamp stays tight. Thanks for the replys.

We've stop on the South side of. Knoxville at a KOA. I checked the clamp and everything is good. No issues. There was an accident on I40 East that shut down both lanes for over an hour.
