Engine Down! Cummins ISB

[offroadpowerspo]

I am new to the forum so I will start with a little history. I have a 2008 Fleetwood Discovery 40X with the 350HP Cummins/Freightliner Chassis. Purshased the RV from Chicago area (I am from Georgia) only because I could not find the floorplan this coach offered anywhere. I have 2 queen beds and one full when everything is set-up and can drop the table in the u shaped booth for another bed if needed. I could not find this in any other coach so I bought this one. I have 3 kids one 17, 11, and 4. So I needed room for them and often times a friend. We love the bigscreen and I like that its not above me while driving.
Found out after long ride home that dealer had hidden smoke smell with Ozone machine. Also found that RV had been at some time infested with mice so I have battled to clean up and get rid of that smell too. All in all, I have fixed alot, cleaned up alot, and replaced alot to get it up to my liking. I am very picky. Even spent 4k fixing some crappy body work the dealer had done to fix some damage.
I flew a friend up who owns a diesel repair shop to look over it with me so nothing would go un-noticed. I negotiated a warranty into the deal. He, another friend and I loaded up and drove home. I had 3 sets of eyes on this thing and we missed alot.
Now, I have had the RV for 6 months and have been on several trips. We have put aproximately 6000 miles on it. On our way home from a week long camping trip in Tennessee, something let loose in the engine. Within a minute I had No Oil Pressure/Shut Off Engine Lights and buzzers and before I could get to the shoulder the engine was gone. Luckily, we made it safely accross 4 lanes of traffic in downtown Atlanta without a collision. Called 15 tow companies before finding one that would touch it. Finally after 4 hours on the side of I75 in downtown ATL we were in our Tahoe following the RV which was being towed. Finally made it home and in the bed around 5 a.m.
The engine will crank, but has no oil pressure and sounds like a bag of gravel is inside. Does NOT sound like a connecting rod or crank bearing. The technician listened to it and said it sounds like a broken gear. Also has no smoke, full of oil(just serviced), and no leaking.
Has anyone ever had a similiar issue with this engine? I really appreciate any input. Glad I have the warranty, because this could get expensive. Thanks in advance for input and sorry for the long story.

First of all, I'm not saying all Fleetwood products are not good. I had a brand new 2011 Discovery 40X and had a massive amount of problems. Engine and lots of electrical issues. Spent more time in the shop than on the road. Kept it six months and got rid of it. I hope you have better luck.

Just to note, Cummins engines aren't a Fleetwood product. They are in many brands of motorhomes, trucks, tractors, etc.

THIS is the reason so many get extended warranties even though there are a lot of others who say don't. If you are the one in a million who will have this massively expensive repair, you are awfully glad you have it. Imagine how the OP would be feeling if he had not purchased an extended warranty. I'm glad it's working out for him.

Which warranty company did you use? Nice to hear you were not jerked around like some companies do.

Oh yeah, thank you for the follow up. Looks like you will have a mechanically new coach in a few weeks.

They pulled the oil pan and found the crankshaft broken in a few places. Do not know what could have caused it, but its likely a defective crankshaft. 22,000 miles should just be getting the Cummins broken in. Just out of 5 year engine warranty, but warranty company is going to cover it. So glad I purchased the coverage. Looks like I will have to wait on my new engine, 4 to 6 weeks from Cummins. Going to miss my July 4th trip.

Thanks for the info on towing coverage, I am going to purchase that ASAP.

I'm glad that Cummins is going to step up and take care of the problem. That would have been one expensive repair. Good luck going forward with the new engine.

You are definitely correct, the good Lord kept us safe and got us home! That I am thankful for. The RV can be replaced.

After fixing this problem, next on your list should be getting Coachnet to ward off the towing problem if there is a next time.

I'll second that suggestion. I've had coachnet for over 8 years and never needed it.....until I was left stranded 90 miles away from the nearest diesel garage. Coachnet sent a lowboy flatbed, loaded me up and set me down in a Freightliners parking lot. Absolutely no charge to me.

There is a lot more good news here than bad.

First off no one got hurt.

Second thing it can be fixed and/or replaced.

Third thing it should be covered.

Forth thing is you now have a good idea of where the noise was coming from.

And last...it should be fixed and up and running again soon. I would suspect it was a manufacturing defect from the start and the fix will outlast the coach.

It is possible that it has had some kind of a front gear train failure. The oil pump and fuel pump are both driven off of the timing gears. Unfortunately, if it has experienced a failure that would allow the camshaft to come out of time with the crankshaft, you may have damage to the valves.

Good Luck

Also,if the engine is a 2008,it could still be under Cummin's 5 year warranty?

Cummins had a recall on one of their engines related to failure of piston wrist pins (or something like that). Call them with your engine serial number and ask about recalls or service bulletins on your engine.

I think that was the Cummins ISL engine in 2007. Sorry for you problems. Let us know how it turns out.
