Wet sleeve explained

[ronmarabito2002]

Greg: I can tell you first hand now, that a sleeved engine is flawed
and the failure of any seal, unless it is idling, will cause
catastrophic failure and total rebuild. This is true especially if
you expect any kind of warranty on the work. Your warranty for a
partial is only 30 days. BIG DEAL!.

I just lost my engine in less than 1.5 minutes from first
indication of a problem.

I'm sure the whole purpose behind the sleeved engine is less
weight and cost in manufacture, but it makes the user the scapegoat in
the case of any failure. To make matters worse, the warranty for a
re-build is awful as it related to motorhome use. The factory only
gives you 12 months and unlimited mileage. A commercial vehicle such
as a long-haul truck can log up to 50,000 miles in that 12 months and
it is a good warranty. The average motorhome owner only puts on
around 10,000 miles in the same period and usually less than that.
Not much of a warranty under those conditions.

I could purchase a used FC for the price of one engine failure in
a Detroit 8V92.

Detroit gives much better warranties on the Series 60, but it too
is a sleeved engine. I wonder what the failure record is on that one?
