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.
