When you blow a piston, the metal shaving go through what first, the oil pump or oil filter?

pump

The shavings fall into the pan, the sump picks up the oil + shavings, goes through the pump, then the filter, then the engine.

So I blow a piston, the shop that fixes it doesn't replace the pump, can shaving come back through the motor, or would they all get trapped in the filter?

If you blew a piston...too late...it already got sucked up through your oil pump and pumped throughout your engine and even your filter wont stop it...you'll find metal debris already in your bearings, to your head etc...it happens almost instantaneosly...

No ... 99% of the debris will be held by the strainer in the sump ... the pump will suck oil through the strainer first and it can be flashed out.

If your shop has rebuild your engine it's ovious that they have replaced the strainer, flashed the oil galaries/pump and but a new oil filter.

So no worries

Well, I blew a piston, replaced it. that shop couldn't get it started so sent it to another shop. They found wiring harness issues and other things done wrong by the shop. Bearing were to small so spun a bearing. When dropped the oil pan there were a lot of metal shavings, come to find out the previous shop did not replace the oil pump. Would this cause the metal shavings?

Yes. You need to replace the oil pump and oem oil cooler, have the head and block cleaned and replace all the bearings. Also check the cylinder walls for scoring. Metal shavings in your engine will cause bearing failure fast.
