I used to work at a GM dealer long ago, and found a product GM recommended
for engine break in their shops.......Its called "EOS", stands for "Engine
Oil Supplement". It was sold in quart can's, I think it was about $6.00 a
can back in the stone age. One can was enough, and you just drained the oil
after the break in was over.
I never had a failer that I know of during the 6 month shop warranty and
way. Of course the engine life expectancy was 50,000 75,000 miles back then.
It was used in all rebuilds or short block jobs. It was also used in
standard transmission and differential rebuilds.
I don't know if anyone remember "Smoky Unick", Top flight NASCAR
owner/driver/engine builder. In his book "Best Damn Garage in town". He
recommended, lightly buffing cam lobes with 1000 grit sand paper, using
kerosene instead of water as a lube while "buffing/sanding".
He's the one that had a Hudson hornet with the engine rotating backwards by
regrind the cam The reason, on the high bank racetracks of the day, by
running the engine backwards the torque would bury the right side tires, so
you didn't have to completely lift in the corners!
How he got caught you ask? He had to put the fan on backwards so it would
still draw air at slow speeds
