Actually, thinking about it a little more, the age of the engine (gas or diesel) may be the bigger issue. Rubber, electrical, and plastic parts get tired after 10-20 years.
I agree about the rubber and plastic parts. I learned a long time ago that whenever I did transmission work on a +100K mile vehicle it was a good idea to
at the very least replace the rear engine seal while I had the transmission out. As far as valve seals go, they're pretty simple to replace without having to do a big-time engine teardown or cylinder head removal, so why not.
