LMM: Ever Seen a New Engine Do This?

[WolfLLY]

My buddy (who is a boat fanatic) told me they had a 1400hp bbc marine engine that wasn’t making the power it should, turns out couple of the cylinders were too high on compression, they drained the oil and ran the motor for 45secs, it evened out the compression on all cylinders and got the motor making the 1400hp it was supposed to make. Boat still runs 130mph to this day, 14 years later. Crazy ass stuff right there. Sorry for the off topic post.

Wasn't borax heated with atf and water then poured down the carb. Called the 20 minute overhaul. Borax took off the glaze. Trans unstuck rings and water knocked off the carbon. Knew guys that swore by it.

Borax was used on band brakes to stop them from squealing in the old friction rig machines when they were glazed over.

Some of that old school stuff is way easier and more useful when far away from home.
