A specifically wrong thread...

On a simple rebuild I would expect the rings to seat almost instantly.
The broken oil ring is a sure sign that somebody wasn't paying attention to detail.
The pieces of metal in the head is beyond comprehension.
And that bearing looks like it could have clearance problems. Hard to tell on my cell phone.
It needs a do over. And I would check the crankshaft too.
Was anybody there to witness the initial fire up?
I wonder if they even bothered to prime the oil pump.
Just my $.02.
