The weak link in these engines is oil pressure due to main bearing and case
wear. If it hasn't had a failure yet there is no reason that it should fail
now. Most likely the end will come from a failure of a support system such
as a radiator or hose failure. My FUN BUS (1987 Syncro Westy) is currently
getting painted but the engine is original, never opened with 254K on it.
Wish I could say the same for the tranny.

The 1.9 engine in my 85 manual Vanagon has 198,000 miles.� Never been opened
for any reason.� Runs smooth as silk.� Gentle driving, burns no oil, always
passes smog, power seems about the same as always.� Wondering how long this
thing can last?� What's the best way to get some idea, compression test?�
