a bit more information, this engine was Don's old engine. my dad and I opened it up today to see if there were any damages to the crank.. but from what we've seen looks like the bottom end might be a goner..

Interesting colour variation on the counterweights from cyl 1/2 and 3/4. Did it spin the big end or what? Obviously the crank is near paperweight stage.

So my assumption of damage was correct! Hee hee!

Looks like the big end has been dropped and im not sure it can be fixed.... the scoring that's on the crank may be fixed but it just depends on what parts you can get to counteract the repairs..... good luck your going to need it

Has it been repaired before?
It could explain the difference in colour.

this is what we think happened, prolonged lack of lubrication on cylinders 3 & 4, and losing the big were the result..

cylinder 3, the bearing was seized on to the crank

cylinder 4, it had a spun bearing.. or whatever it is called..

discoloration was also caused by the lack of lube, probably had no chance in cooling down..

colouration is def due to heat. It had been complaining for a lil while. It doesn't take long without oil pressure for a bearing to let go or get so hot it gels to the crank.

and no possible way of knowing til it bites you in the ass..

I wonder if what would be the possible visual signs of this time bomb?

There would have been noise...a bit of it too. Sometimes people mistake it for noisy lifters, but for a 'trained' ear it's easy to tell the tap/knock is from the bottom of the engine.
