I've got the motor pulled out and halfway torn apart, I have to wait on a crank pulley puller to get the rest out, but at least I know now what the issue is with the motor.
Lots of metal shavings. Rod #1 has about 3-4mm of play to it on the crank.
Here's the main piece I've found so far. Looks like rod bearing to me.
I'll probably add a few more pictures once I get the oil pump off and the rest of the assembly removed. Thanks for reading.
