Turbo charger

We just bought, Friday Feb 13, a 2006 coachman sportsman 37signals with a 30th cummings. They gave us a 3 month 3000 mile limited extended warranty.

we bought them coach from pedata rv in tucson.

we drove the mh over 200 miles and then the check engine light came on.
no decrease in speed or smoke coming out of the engine etc.

Stopped in Tucumcari nm at Johns truck service and put the cummings computer on it and it shows the turbo charger acting up. Per John it needs replaced.

My ew says the turbo is cover if failure is due internal lubricated parts. Turbos don't have lubricated parts.

I checked wholesale warranties and coach-net and they say the same thing.

Have you had your turbo charger replaced under extended warranty? If so did your warranty say lubricated parts?

I might have to pay $6,000 if ew doesn't cover it.

IMHO....Turbos cook the oil in their bearings if the motor is turned of before being allowed to cool a few minuted after heavy drives, like a climb.
The oil in the turbo does the cooling.
I'd say go for the fix.
Best wishes!

The bearings in the turbo are certainly lubricated and they are generally the failure point but the Cummings Holiset VGT has other parts that can fail.

Turbos do in fact have moving parts and the bearings float in oil. If the coke like was mentioned above they quit. In normal driving you don't need a cool down, and even a hard pull just going off an off ramp is enough cool down. Now, stopping in the middle of the Grapevine would require a cool down.

At $6000. I would be looking at another shop. Usually when a turbo fails it is pretty obvious.

I have had engines shut down on extreme hard pulls without killing the turbo. It is better to idle them for a few minutes of coarse as repeated shutdowns will definitely cause damage.

To the OP:
Your dealer is paying for it. If they wanna pay the $6K, fine. Otherwise THEY get it towed to their mechanic of choice.
Easy-peasy!

Did you call the selling dealer? They may want to get involved since there was only 200 miles since they sold it.

Sales are AS-IS, even though you got some protection with the extended warranty, but if the coach was traded in due to a bad turbo and the dealer knew it, all bets are off and they're on the hook for the repair. Proving it, is as simple as calling the last owner.

It's always best to see if they want to help in the repair...it's good business.

First question is whether Pedata actually provided a warranty of their own or simply included an extended warranty policy as part of the selling price. If they are guaranteeing it, you need to deal with them. If they handed you a policy with a third party and gave no warranty of their own, you have to work with the extended warranty provider. You would have no recourse with Pedata unless they had prior knowledge of a turbo problem.

Turbos do indeed have "internally lubricated parts", even though they may not receive lubrication from the engine oil system. Sealed bearings are still lubricated. However, warranty companies have been known to claim wear & tear or abuse to avoid paying expensive turbo claims, so document the failure circumstances well and be careful how you describe what happened. Be prepared to argue too.

Turbo's can also be rebuilt by a turbo shop and doesn't cost $6000. Had lots of them rebuilt in the trucking business.

X2, Rebuilt would be my first choice at much less than $6000.

You're dreaming if you think a dealer will pay for anything on a used coach he sold, (unless the buyer has evidence of misrepresentation or wrong doing).

When I purchased this rig I found it needed the turbo replaced because the PO had not taken care to let it cool down after hard runs and it cooked the oil seals. Brand new Holset VVT turbo $3,500. Keep shopping

I will admit I am not an expert on diesels but every Turbo I have ever seen, or heard of, had lubricated parts.. (Bearings)

Could it be you do not think they have lubricated parts due to the absence of grease fittings? They do not have those, they get their lubrication from the engine via the oil pump.

As someone else said they cook the oil rather well so it needs to be replaced swiftly, and the hot oil drained back to the crankcase where it can cool off a bit.
