It seems all the makers are selling us bum engines. Some GM engines will
suddenly leak coolant through defective intake manifolds. All the Japanese
makers use timing belts with non-free running crankshafts - a disaster
waiting to happen. The list goes on and on.
Continental, Lycoming and Pratt & Whitney don't seem to have any problems
with their engines. Maybe car makers should contract out their engine
design and production to them to finally put an end to auto engine
problems. Of course, the Government will have to "certify" them to ensure
no short cuts are taken by these reputable engine makers as a result of
cost-cutting pressure by Detroit Iron.
Within one human lifetime, we have seen cars go from $2000 to $20,000 and
more, yet we hear the same old excuses: every nickel counts; it costs too
much to build no-compromise automobiles. Now we know no-compromise is the
only answer to domestic car makers' survival; anything less is ripoff and
the customer base has finally realized it.

Not all, and not just Japanese. American too.
When's the last time you owned one? Ever heard of ADs? Airworthiness
directives. You fix it or you don't fly it - doesn't matter if yours
is having a problem or not. And it's YOUR dollar, no matter the age.
If you had to drive behind a LycoSaurus we' hear you bitching from
coast to coast without a megaphone!!
And what's an O200 Lycoming engine worth? 200 cubic inches, aprox 80
HP and $40,000 for the engine alone.

Not if you change the belts. BTW, the camshafts are free-running. The
valves are another story.
make about 75 HP. Not enough for cars today.
And are very expensive and require tons of maintaince for their engines,
as required by the FAA. I would prefer my car engine to break down than
the engine in the airplane I am flying in.
Gee, so you want them good and cheap. Sorry, it doesn't work that way.
How much have cars increased in price when considering inflation?
How about when considering the improvements? Cars today last 300,000+
km. How far did they go 30 years ago? 150,000 km if you were lucky.
Factor that in now.
I am building an airplane and have an informed amatuers knowledge of
the airchraft engines. Generally speaking, they are quite simple
engines with few of the bell's and whistles that you find in auto
engines. They rely on large displacements for their horsepower as
opposed to high RPM. This helps them last longer.
I noticed another person commented about airworthiness directives. If
a problem is found, the government mandates that it be fixed, further,
the fix must be applied by a licensed mechanic. In fact, all repairs
to the powerplant and airframe must be performed by a licensed
mechanic and he/she is required to sign off on the repairs. The
government also requires periodic (annual) inspections). If the plane
falls out fo the sky, the government comes back to the mechanic. I
believe this all results in a generally high level of repairs and
Still, an aircraft engine is considered run out at a little over 2,000
hours. Given the cost of new engines, they are generally completely
inspected and rebuilt at that point. Granted, they would last longer
and this is largely a safety point. If you consider an average speed
of 40 mph for a car, 100,000 miles translates to 2,500 hours of
driving. I generally drive my cars for twice that and only once have
had to do a rebuild. I know its not a one to one comparison but
still, the point is that car engines are pretty reliable.
