Today I was getting my A15 powered wagon ready for summer by changing the oil and filter, as well as finally getting around to changing the cooling hoses, thermostat, and flushing the system.

Anyway, I realized that my oil drain pan had a bunch of metal on it when I was done changing the oil :( Appeared to be mostly coppery-looking metal, with some black-brown crusty chunks of metal mixed in as well
I noticed that theres a rattle when the car is running...at first I thought it was just a pipe or something clanging around under the car, but I'm pretty sure its in the engine. The engine is also puffing a bit of oil smoke, mostly when cold, but a tiny bit when warmed up as well. Other than this, the car seems to run just fine.

What does this sound like? I'm thinking that the main bearings are being chewed up. A friend thought it might have been the thrust bearing on the crank...I'm honestly not sure what it is. Help is appreciated!
