No not maintenance.

So what repair do you believe to be needed for
ironblocks to achieve 300,000 miles?




If it was a 1950 Chevy, rings and bearings about 3 or 4 times. Oh, at
least one or 2 valve jobs too.


It's like the career that I was fortunate to retire from at 40 was a
dream. I did not really witness all the problems the these GM engines
had. Chevroley big block engines, in the 60's and early 70's, did not
really have an inherent cylinder, that was every ones imagination.
Fords recent V8 is not really blowing the spark plugs out of the heads,
that is the owners imagination. GM's v6 and v8 diesel engines did not
have lifter problems, they are supposed to run like that. I stocked 2~3
complete engines at all times. It was very common to replace complete
engines. I recall the 3.8 V6 crate engine was less than $1000 so it was
less expensive to replace than to overhaul. I could get a new engine
from GM in less than 3 days but kept them in stock for our shop.




I do know of two Toyota Celica that reached that mark. Engine ran great
but the body was pretty well rusted out. See through fenders for good
ventilation.

Then there was the Vega. I drove my brother's to California when he
moved cross country. It was never the same after that.
