Reminds me of my buddy's bug. He installed a new engine and his friend drove it around the block. Next time he went to start it, nothing. I checked it and it's seized hard, can't even turn it with a prybar on the flywheel teeth. The oil pump cover has a ton of sealant that oozed out, guessing the same amount oozed in and fucked the motor. He's dropping it off for a teardown in January, then I should know for sure.
Another buddy smoked a new hot rodded 4.6L Mustang motor. He pre-filled the oil filter so the pump couldn't evacuate the air to prime itself. By the time he asked me and I told him what to do it was too late. It made oil pressure, but it was knocking.
