When you have a new motor on the engine stand and have an oil filter on so you can prime the oil to see how the rockers are oiling, BE SURE you have an oil pressure sending unit or have blocked the plug at the back of the block. Oil is really hard to get off a 14 foot garage ceiling and the walls. OH and it would help to look up once in a while when you are priming with a drill to see if anything else is happening, like all of the oil going up on the ceiling.
ASK ME HOW I KNOW.. stupid happens.
