Getting the hose off was far harder than getting it back on. I found some pictures online of what I wasn't looking at which helped me figure out what I was feeling.

Engine has been sitting a little under 2 years, I think. I just used 10w-40 which is what the 4age takes. I'll run this for 500-1000 miles or so and change it. I'll also be keeping an eye on it to see if it gets dirty faster than I expect. I oughtta put some seafoam in the oil too.

Starter vs hand-crank is kind of a personal choice, I suppose? It's hard to get to the crank bolt on this engine. For what it's worth, with the spark plugs out, the engine doesn't even sound like it's turning over; I thought the starter bendix had frozen up at first. So I don't think spinning it with the starter puts too much force on the crank and cam bearings.

I don't think the rattle is motor mounts since I've got urethane inserts on mine. Current thought is maybe exhaust, which would make sense since it's been rednecked together. I also recall a mystery rattle from before I parked the car, so odds are that that didn't fix itself by sitting. The constant rattle could also be an alternator bearing since it's coming from that part of the engine and it's a crap Autozone alternator that has given me nothing but sorrow.
