1987 F-350 with the coolant in cylinder: We have a suspect

I posted about an overheated F-350 I bought with a 460 with obvious signs of overheating in its past. I’ve disassembled it down to the block and the block was dropped off at machine shop today. I still haven’t been able to figure out WHAT caused the overheating issues. Obviously low oil, low coolant, or a failure of one or both to circulate would be the obvious answer.

But the oil pump looked fine, the water pump looked fine, the thermostat was functional. Then I noticed the oil pick up has a pretty considerable dent in it. Two actually. The screen is fine so I kind of ignore it and keep going.

Anyhoo, I marinate on these weird dents for a couple days and then I notice that the dents coincide with the intake tube on the backside and I wonder if those pushed in dents could be restricting the oil intake -even partially. The locations are ideal for maximum obstruction.

So I try and figure out how the hell the oil intake got smashed repeatedly like that. It doesn’t make sense. There’s nothing IN the oil pan except for the big, thick, long drain plug and that’s at the bottom of the pan.

And I think that’s the answer. Someone either was trying to force out the oil pan through the chassis with the oil intake still mounted and the engine not lifted high engine (service manual says 4” minimum) and they were stabbing the drain plug in to the very center of the intake while they wrestled with it, or they unbolted the oil pump and intake and it fell on to the drain plug and nailed the exact intake point. Hard. Twice. (Personally, I think the first option is the most likely.)

Long story short: Does this make sense to anyone? Do you think this could be what happened and could be restricting oil flow -and leading to over heating?
