Oil blockage on opposite sides of the engine is a slim possibility, recent "rebuild" or not.
If the upper cylinder area has no lube, the cams and rockers would show signs of it. Please confirm.
It could be a "simple" and coincidental case of both lube bars clogged and not able to spray or other issues such as:
No oil
Oil pressure relief valve stuck open
Oil pump shaft broken
Oil pickup tube, broken
Intermediate shaft or gear, broken
Conduct more investigation (e.g. chain boxes) to understand the extent of the damage or lack of lube.
Unless there was an implied warranty attached to the sale, there's probably not much legal leverage on that front. But understanding the extent of any damage should be the topic to address. Is this DIY or are you handing this off to a repair shop?
