Bus Repair Questions and Answers

Question:
1970 Volkswagen van 1600cc mileage: 600. Hi and
thanks in advance for your site. We have been
enduring a nightmare with NEW engines in our very OLD
Volkswagen. It began in May of "99" when my wife
and I decided to put a new engine in our 1970 Volkswagen
Van. I won't go into the awful details of how long
it took, but in AUGUST! Our mechanic had the job
finished. That engine lasted all of just under a
thousand miles when it lost all compression in it.
Mind you, we were very diligent about changing the oil
and getting the valve adjustments done on time in all of
these cases. It was determined that two of the
heads were bad on the engine and they were replaced.
Again, about a thousand miles after that, the engine
totally blew out. This time they installed a new
engine, which is now going out again after just 600 or
so miles. My question, could there be
circumstances within the vehicle that are causing these
engines to blow? It's very odd, because the
Volkswagen engine is so simple to begin with. The
mechanic says it's not his fault, the engine company
(GEX in California) says it's not their fault. We
know it's not our fault, but we're stumped nonetheless.
Thank you again, Tim and Debar
Answer:
It is very difficult to say why your engines failed.
One thing that comes to mind that is very critical on
these engines, is the oil cooler. Check it to see
that it is not plugged and gets sufficient airflow over
it. It is our practice to stand behind any engine
replacement we do and your mechanic should warrant his
work and engine.
