A friend of mine recently bought a 1996 Chrysler Town and Country with the 3.8L engine.
The van has around 200,000 miles on it - really up there. Maintenance looks to be at least average if not better. The transmission has recently been rebuilt.
Any guess as to how much engine life remaining? It runs well at the moment. What's the most likely engine failure mode?

It is not unusual to get 200,000 or more miles from a 3.3 or 3.8. It's an old style single camshaft with pushrods design.
Early 3.3's had a problem of rocker arm towers cracking at 150,000 or more miles, but I believe that was fixed before 1996.
Other than that, it would be the usual stuff, such as piston rings, rod and crank bearings, and valves. The timing chain could be stretched after that many miles too. A visual inspection would be the only way to know for sure.
Does it use any oil? Are there any noises that would indicate any worn parts?

As long as its well cared for, there's no fundamental reason that it won't last another 100k miles, maybe 200k. Maybe 300k. The 3.8 has a chain timing drive, and there's nothing that will likely fail suddenly. Most likely, the bearings will slowly wear until it starts showing low oil pressure at idle, or oil consumption may creep up as the rings wear. Even then, rolling-in new bearing shells would keep it going a lot longer.
If you define failure as a broken connecting rod or broken crankshaft, you might say nobody knows when failure occurs. With high miles you usually see leaking oil seals, oil burning, noisy valves and loss of compression and power due to bad valves or worn rings. Lots of things could have you call a tow truck. Dead fuel pump is a common problem. Your alternator can go at an inconvenient time. You already had problems with the trans.
