My fairly new to me 01 Monaco Dynasty, with the 350 Cummins and 61,000 miles just had a major engine failure...cam is damaged, cam gear dinged up pretty good, and two push rods bent. Anyone have any ideas what might have caused this at such relatively low miles? The shop in Corning, CA. that we are stuck at for repairs (we were on our way to Salem for the Rally and then on to Redmond) says it is highly unusual for the 350...it is, in their opinion, a highly reliable motor. This was really our first major trip since we bought it earlier in the year.

Sorry to hear of major damage.

We don't hear of many reports like this.

Hopefully the shop can pinpoint the cause.

While discussing probable causes with the tech today, he said "god only knows"...now I know I make the wife mad from time to time, but didn't think I had done anything to annoy the RV gods

I just scares the heck out of me to think of being stuck like that.I hope for you and yours things get better.

LoL-on a lighter note(J/K)is the shop letting you sleep in the motor Home while it is on the rack?.I'm sorry-I'm just trying to bring a smile to you all.All things will pass and at some point you'll be able to laugh about this time.

We'll have a good thought for you tonight.

Sorry to hear about your engine problem. It is one of the worst nightmares for a diesel MH. The engine and transmission are nearly bulletproof but having to do major repairs or replacement of them is not in anyone's normal budget. I deduce that you have a Cummins ISC. I suggest that you contact Cummins since they sometimes have unofficial recalls and they might help with the cost. Cummins is a good company and they don't think that their engines should fail either, and they usually don't. Did you or the previous owner install any upgrades to the engine. If so Cummins will likely indicate that this was the cause of the problem.

Based on my "limited" knowledge of these things, I would think that a mechanical part just failed because of a manufacturing flaw, or a lubrication problem.

If it was a mechanical failure, there may not be much concern over why it failed. Sometimes they just replace all the bad parts, and you're good to go.

I haven't owned it long enough to do anything...it did have a Banks system installed by the original owner...
