Content-Type: text/plain; charset=us-ascii
The Air Cooled engines, particularly in a 5000 pound Westfalia are a
ticking time bomb. Consider 67 HP doing all that hard work. In effect
running at 100% capacity a good portion of the time. Its only careful
maintenance and moderate driving that delivers the longevity.
I've always been guilty of running mine hard on the highway at 70-75 but
reading the signs and slowing down on long inclines or bucking head
winds.
I blew #3 cylinder at 85 MPH fighting a headwind of 15 mph. It broke the
rings, ring lands, scored the cylinder and blew oil out on the guy that
was tailgating me at about three feet.
The oil showed up on the rear window (and his windshield) long before the
oil light came on and I got it shut down on the service road right when
the light came on for the first time.
I was 250 miles from home but managed to get back home by putting a quart
of oil in every 35 miles or so.
I wised up pretty quick when I installed new cylinders/pistons/rod
bearings etc. Luckily the heads were not damaged, but there wasn't any
way to shave the repair labor down to less than two days.
I've got to admit that happened within 90 days of buying my Westy and I
didn't know nuttin about the proper care and maintenance of an air cooled
engine.
