After talking to my local vw mechanics a while back, I concluded that
the vanagons they had in for frequent engine replacements had one thing
in common: drivers who thrashed the engines. That of course stands to
reason for any car, but 70 mph seems to be the magic number for
vanagons. I was looking at an 89 syncro on its third engine. We talked
about a dozen or so other customers who got 80K miles or less on their
engines, and the anecdotal evidence was that the drivers of those
vehicles reported commonly driving way over 70 mph. The syncro had
commonly been driven 80. Other customers had driven faster than that,
and had come back for replacement engines more frequently.
These replacement engines came from a variety of sources, including
ones rebuilt by the shop.
My 90 has 192K miles on it. It doesn't burn or leak anything. It runs
strong. The heads have been out once to replace the rubber gasket, but
no valve job has been done. I NEVER drive over 70. Maybe for just a
minute or two while passing, but the van has never been 80 at all,
ever.
My mechanics were remarking that the other long-lived engines had
drivers who reported driving similar slower speeds.
There may be plenty of evidence out there to the contrary, but it seems
to me that when the VW engineers placed that green area on the tach,
they meant it. Maybe there is a threshold rotational speed above which
the centrifugal force and inertia of the rod is great enough to ovalize
the journal hole.
Anybody else? I realize that I and others may just have luckily gotten
a better balanced or otherwise better-fitting engine. But just asking
around, it seems that speed kills these things.
