I've got an '81 engine ready to go... free! (Just pay shipping!....uh, that usually runs around $265...) (And it might need some valves.....and a few springs......cams cleaned up.......gasket kit........clutch plates.....o-rings......water pump seal........and a partidge in a pear tree! :smilie_happy: )

The jugs are rusty cause they been sitting for years now.Maybe 6 years at least.That jug was a messup from the person that bored it.I'm showing one of the cylinders,the rest came out ok (BUT YOU NEED ALL THE JUGS TO BE DONE RIGHT :mrgreen: ) the deep grooves at the inner bottom with subsequential cracks is done by the machine itself.I guess is failure to grip properly the piece to bore or the boring tip itself comming loose under stress at work.AApple":cjq0dh9j said:

Looks like it was bored off-center. I wondered if that was a crack down there, or just a scratch/gouge. Just goes to show ya don't always get what ya pay for... :sensored:

What would make the steel sleeve crack like that?
Extreme heat maybe? Parts not secured and getting away?
Looks like that engine had spun a bearing.

The deep groove wasn't there(before the machining)which produced the cylinder separation at the bottom.The small crack at the left could be from too thin cylinder wall if jug wasn't centered correct.I've sent it to bore 0.75mm over standard.Cylinder one had a tiny nick from a broken valve braking off and gouging the cyl. wall a bit.Would have known the outcome of the machining :swoon: .I would have just deglazed jugs and period :mrgreen: .

You could get Mcgoverns engine and swap out cylinder sleeves.
