Blown Engine

Has anyone experienced a blown engine on an E-450 Triton V10 6.8l engine. I have just over 23K miles on my 2013 Coachmen Leprechaun 319ds motorhome and my engine needs replaced. I would appreciate feedback from anyone on this.

Nope, that's a very solid engine platform. But they have been known to occasionally break a lash adjuster and eat a valve. What is the engine doing ?

Agree with Gashog, that is a stable platform that has been used by Ford for many years. The 4.6, 5.4 are proven platforms. they have there problems but blown engines at that low mileage is a concern. Did she have regular service? Overheated?

The motorhome was towed to a Ford dealer and they did a diagnostic on it. They said that it was shot and ordered a long block to replace it. Just had the oil changed a week before this happened, and before that there was regular service performed. It never overheated. I was driving back to Denver, from Green Valley, AZ on I-25. I heard a clacking sound, looked down at my guage's and the oil indicator dropped and the oil light came on. I immediately pulled off the highway.

There was that one thread on 2013 V10s with oil problems, I think he got to the point he blamed a bad gasket on the timing chain tensioner on one side, it was leaking enough to reduce oil pressure and the engines were dropping rocker arms:

Was the failure at the bottom of a long downgrade? We’re you using the engine compression to slow the camper down?

I’ve heard horror stories on those quick lube oil change places screwing up, not enough oil, leaving old filter gasket on (two oil filter gaskets can lead to oil shooting out from between them). Check for leaks/small puddle at the last place you parked before she died.
