oil additive may have toasted my engine

As far back as I have seen it advertised (at least as far back as the mid
'60s), it's always been the same as it is now: A thin oil containing a
dose of detergent chemistry. The fast-flush gookums are made out of active
solvents and/or Butyl Cellosolve.

Not sure about this, but in the past I've run diesel fuel in the crank case
for about a minute to flush it. I don't recommend it by any means because I
always thought it was dangerous.

What I call "sudden flushes" like that are not advisable if there is
significant sludge. People who do those are taking a big risk with the
engine. A gentle, controlled cleanout is less likely to cause
catastrophic engine faliure.

Deisel, or Kerosene, is MUCH better than harsher solvents like varsol,
as it does not dry up the sludge turning it into "clinkers".
The only sludged engines I have had fail (after me working on them)
were my brothers old Vauxhaul (which we did nothing to, other than
change the oil and drive) and his '65 valiant slant 6, which we did
not flush - but we DID chip out a lot of crud to get to the valve
adjusters. We though we got most of it out, but obviously enough crap
stayed loose in the engine to block the oil pump pickup screen (dead
in less than 10 miles).
I have used Kero (and deisel, and stove oil), ATF, rislone, various
engine flush products, and never had a problem with any of them in
over 35 years.

That's the first I ever heard of anyone killing the venerable, a moment
of silence here, for the great, tank-like, slant 6. Kudos!

I tried, 300,000 miles. Nothing could kill that engine for me.
The body would rot away. Leaving the engine still going but
hard to drive a car when the body and other necessary parts
start to rot. The odometer would just keep turning over,
100,000 miles here and there, starts to add up after a while.

Me too, I thought they'd run without oil pressure. Eventually you just have
to give up trying to wear them out, or maybe get in a wreck.

I don't think the previous owner had ever changed the oil - and after
a bit better than a year of driving with noisy valves brother decided
he wanted me to adjust the valves. Could hardly find the rocker arms.
Didn't have any flush fluids around, so we decided to drive it back to
town and flush it the next day. Didn't get back to town before the oil
light came on and a main bearing spun.
Pulled the engine and the pickup screen was totally plugged.
Big brother bought a new car, and little brother "inherited" the
Valiant and rebuilt it while he was going to high-school. He put on a
2 barrel, split exhaust manifold, and a bunch of other toys trying to
make it go better than my old Dart and Valiant had gone. I was out of
the country when he got it back on the road, and he had sold it by the
time I returned - so I only have hearsay evidence that says it was
perhaps a little faster than mine - and had a lot more bottom end.
Used to have burnout contests with his buddies with 304 gremlins, and
apparently did quite well.
I personally never got rid of one with less than 100,000 miles on the
clock (usually bought them just shy of the 100,000 and drove them
another 3 or 4 years)
The "leaning tower of power" was a great engine and responded well to
tuning (204HP @ 6250 RPM 170 cu inch)
