Had the same issue last month. Was following an SUV pulling a TT and had my 5ver in tow. He was going slow on a 4 lane highway so I moved over and stepped on the throttle. Just as I got almost around him then BOOM. Scared the heck out of me and then thought the engine blew as black smoke was rolling out and power dropped within seconds. Popped the hood and seen the downpour was off. Had to let it cool, outside temps were in the 90's and working over a hot engine was such a pleasure on the side of a major highway with the 53 footers flying by @ 70mph. Got my tool box out and finally got it back on and tightens up, knock on wood it hasn't happens again.

Please Refer to GMVIS Supercede:
This bulletin is being revised to update the model years. Please discard Corporate Bulletin Number 09-06-93-001 (Section 06 - Engine/Propulsion System). Condition
Some customers may comment on an engine oil leak from the rear of the engine near the flywheel housing. Upon further investigation, a technician may find oil in the charge air cooler or turbocharger air inlet adapter.
Cause
Note
Oil found in this system is very rarely an indication of a turbocharger failure. This condition may be caused by a loose clamp at the inlet duct/pipe located on the turbocharger. Oil may carry over from the PCV system and leak out the turbo inlet duct/pipe.
Correction
Note
Do not replace the turbocharger if oil is found in the charge air cooler pipes. Important
When replacing the clamp, tighten the clamp to 5 Nm (41 lb in), then loosen and re-tighten to 5 Nm (41 lb in). OIL LEAK FOUND AT CHARGE AIR COOLER OUTLET (HOT SIDE)
Clean the rubber duct hose with soapy water and allow to dry. Apply a thin bead of high temperature RTV silicone sealant to the turbocharger compressor outlet port and CAC duct connections.
Tighten
Tighten the clamps to 8 Nm (70 lb in). OIL LEAK FOUND (Full-Size Pickup Trucks - Silverado and Sierra)
Replace the turbo inlet duct/pipe and clamp with P/N 98011738.
OIL LEAK FOUND (Vans and Medium Duty Trucks)
Replace the air intake clamp with P/N 97376379. Refer to Air Intake Pipe Replacement in SI.
Parts Information
Note
Do not replace the inlet adapter/duct on vans and medium duty trucks - only replace the clamp.

Turbo Hose

Hi. Hi Everyone
My name is Phil C. and have a 2008 Chevy C5500 Duramax 6.6 LMM Motorhome Jayco Seneca Kodiak Chassis. As I was traveling from AZ to the east coast we had the Hose blow off the turbo on the driver side, I hooked back up after cleaning off, and got me back to NY. I then was on my way to the get the frontend worked on when the hose came of again, We had a new hose put on GM #15020972 I noticed that hose had crakes in it and warn out. the plan is to replace the other hose that's on the Tube that go's from the turbo to the intercooler, Is there anything else that I need to know or have to check out.


If anyone can help please call me at (845) 629-5416 Am trying to get help with my 2008 6.6 LMM

Did you read the preceeding post? Best info available that I am aware of. I had this same problem on my truck and the dealership did exactly what the Technical Bulletin said to do and it has been good for 75K miles since the repair. I think you should do the same thing. The key is the correct procedure for cleaning and adjusting the correct clamp in the prescribed manner with the proper torque spec.

Hi Ron
Thanks for the info, I had some time today to pull the intercooler OUT and it had a small hole at the bottom of it and you can see the were it was leaking black soot out of it, Now am try to locate one, part # 15843434 that's what is on the sticker on the to of it. That Sealer #97720043 RTV Sealer should I use that on the hose's, Or should I use Hairspray like some people are saying. LOL
The motorhome is parked for now till Oct. This the biggest work I have done the unit since I got it. It's easier then working on my over the road trucks LOL Phil

I've had mine off a couple of times for work elsewhere. I cleaned 'em and used red RTV (what I had) and tightened "alot", but not measured. Never an issue. Slight oil inside each time. Only have about 71,000 miles.

Oh, I've used synthetic motor oil at least 50% of the time. I heard somewhere that it is good for all the rubber / silicone. Idk.

My best fix was clean the crap out,buy some good boots and clamps never had the problem again , I used PPE boots and clamps , much better quality boot and clamp and cheaper than dealer crap. PCV reroute helps but will not eliminate the problem

Turbo & Hose

Hi everyone
This is the first time this has happened to me and I found a couple of things that may have course the hose to come off, The hose's have been on the unit 2008 Chevy C5500 6.6 LMM Kodiak Motorhome for almost 8 years, and they were warn & cut, I got a lot good advice on here on how to fix it. But as I took everything apart (the intercooler hose's and the Intercooler) I found a lot of other things that were damaged, The intercooler had a Hole in it, and the plastics tube hose that go to (cold side) of the turbo, (passenger side) had a hole in it also. WOW


Am glade that I have the time at 75 to check all of these things myself.. LOL.


Again Thanks everyone for the help. Phil
