Richard. the 5.9 Turbo diesel si one of the most rock solid engines
built. Many a *workin' mansDodge pickup has run them *with little
maintenance over oil changes for 400,000+ miles.

In anything else, ask for an oil analysis test. *I'm sure you're
familiar with it, but maybe not. They suck up some engine oil, send it
to have sampled then the lab can tell you a lot aboutt he internals of
the engine. Just like a blood test. amazing what they can find in
there.

Of course if it was freah changed befor moth-balling, it wond be of
much help. but if it's seasoned oil, it would be to your benefit. the
testing is cheap too.

Good information regarding the 5.9 Turbo. *Thanks. * I suspected they are
good engines because I really can't find anything negative reported about
them. * Even if they typically need a rebuild after 5000 hours, they would
be fine for me. * I doubt I'll put more than 50-100 hours a year on them..

As I mentioned in my original post, the oil was changed at lay up last fall,
so an oil analysis won't be very meaningful.

Sorry, I missed your statement about the oil change. But one thing
about the 5.9 cummins is it's popularity obviously because of Dodge.
Now I don't know about a marinized version which would be manifold
and possibly turbo, and don't know about the labor, but even so, a
NEW (not reman) longblock engine is less than $8,000.00 USD from what
I understand.

BTW, not counting the long lifespan, they're also a very economical
engine. PLUS there's lots fo tricks that can be doe tot hem to gain
major horsepower safely.
