Holy CATASTROPHIC engine failure, Batman!

I have never seen an engine, whether it's B&S or Tecumseh, fail quite like this before.

Picked up this old Craftsman branded Tecumseh 8HP engine to put on my Craftsman II 5/23 tracked machine as the original 5HP just wasn't doing it for me. Long story short, the 8HP engine burned far too much oil than I ever expected...

And now I know why.... Behold!

The wrist pin clip was found in the bottom of the engine. Being a rebuilt block, something tells me the re-builder did something wrong, the clip came out of the piston and the wrist pin began to shift digging into the cylinder wall.

Have any of you encountered something like this?

Don't ask me how I know this but if you're a young kid just getting started with engines, have an engine apart, lose one of the clips, and replace it with a bit of bent paperclip that can happen...

~1994 Ariens 924084 (ST1032) "papa bear": restored, re-engined, real nice!
1991 Ariens 924050 (ST824) "mama bear"
Toro PowerCurve 1800 "baby bear"

Be alert! America needs more lerts.

I'm confused... the wrist-pin scoring was in the 5HP or the 8HP?

you guys joke... I would try to fix that scoring with JBWELD esp if it's a cast-iron sleeve and the piston didn't get ripped-up... all in the interest of SBF science of course!

These are aluminum blocks with cast iron sleeves right? Can these things be re-sleeved? Is it worth the money? If so, I see an opportunity for a bore and stroke..

That is the oil burning 5HP, At least that is how I read it but I also read auto correct very well sooooo...... LOL I do believe the oil burning 5HP is the engine, He says it burns oil and now he knows why.
