One of the problems with the Waterboxer is that the lubrication system is
marginal for pressure and temperature. As such it is possible, in fact quit
easy to put the system into a thermal runaway causing oil pressure loss and
the resulting engine failure such as a thrown rod or seizing a main bearing.
Having a perfectly working cooling system will not ensure the oil doesn’t
overheat to the point of failure. Any of the following conditions can cause
a rpblem:
Excessive oil level
Wrong viscosity
High engine speed and/or load for an extended time.
With a well-designed oil temp and pressure guage system you will soon learn
what is normal and how different conditions can cause changes.
During extreme conditions you will see when it is time to back off before
damage begins. You will also see if additional oil cooling is needed for you
driving conditions.

Thanks, Volks, for the insight into what to expect when a well-maintained
and gently driven Waterboxer starts to reach the end of it's life, which
appears to be in the 250,000 mile range or so. What I'm taking from the
discussions is that the exact number isn't so important or even known, too
many variables. But what is important is that there will be some warning
beforehand: the gradual appearance of the flickering red oil pressure LED.
The general feeling I'm getting is that catastrophic failure is still a few
thousand miles down the road after the initial flickering begins; hopefully
enough life left to hightail it (or limp) back home to San Diego from pretty
much anywhere in the USA.

Stuart,
Thanks, that's helpful information; I'll keep an eye for that oil pressure
light flickering. I've had an occasion recently of very faint dull red glow
from the LED at startup and idle, which subsequently quickly faded away once
at operating temperatures.
Reason I'm asking is that I'm trying to plan for the future. I've been know
to take some pretty long roadtrips in my Vanagon, like 10K-12K miles at a
crack. That would be unfortunate, to have to decide on a rebuild or Subie
conversion while on the road thousands of miles from home base, lots of
downtime too and expense. And still not sure what my long term travel
plans are, to keep Vanagon-based for the next 10 years or upsize a little to
something like a Sprinter or the next generation Ford Transit scheduled for
USA manufacture in 2014 (latest rumor). I still really appreciate the
handling of the Vanagon and garage-storage capability, both of which would
be compromised by a larger van-style rig; I don't know if even a small Class
A motorhome would suite my style which is on the "minimize" side. And I've
been a VW Van owner since 1974 so it's in my blood now.
So if my current motor would be good for another 25K or so, it would buy me
a few years time to dial in my long-term options. I know at this age of the
vehicle there are just so many factors to take into account regarding
overall vehicle longevity, but I appreciate the helpful List advice on this
issue.
By the way, when I said it doesn't "burn oil", I guess it would have been
more accurate to add "excessively"....I use about a half quart every 2000
miles.

Rich,
Just drive on, and forget about it! If you do a compression test, what will
you do if it's low (and it will be)? The death signal is when the oil
pressure light starts coming on or flickering, particularly after a long run
on the freeway. When that happens it's time for a rebuild, or if it get so
gutless a passenger has to help you push it up hills.
My '84 went over 200,000 miles and was running strong, but I replaced it
with a used 2.1 just for the fun of it years ago. Bad idea. I blew that
one up (http://volksweb.relitech.com/21rodbrg.htm) and I don't have that rig
anymore.

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?
