MMO? Minimum Municipal Obligation?

Yes, I put fresh oil it, but didn't change the filter yet. The filter only had about 300 miles on it before I pulled the engine. Maybe I shlould just swap that out too since it's only a couple bucks. I've been using 5-30 year round.

Grabbed a couple coronas, started it up, and let it run for about an hour last night. It has calmed quite a bit, still not perfect, I think a couple of them still need some time. Definately a 95 engine. I don't think it was well taken care of before me, it had 145k on the original plugs, wires, and timing belt. Definately a strong engine though. Thanks for the feedback!

Just got done putting my engine back in to a 95 Impreza 2.2. When I had it out I replaced all the oil seals, valve guides, head gaskets, intake and exhaust gaskets, timing belt, water pump and any other piece of rubber that was rock hard. The first start (after sitting on a stand for 3 months) surprisingly started like it was just run yesterday. Idle is smooth, no misfire, no smoke, except the valves are loud as hell. Sounds like all of them are just getting a beat down. We recently had a bit of a heat wave here in the midwest so I didn't work on it for a while, just too hot in the garage. During that time the heads where sitting on my work bench, mating surface down. I've read (now) this is a bad idea and this drains the oil from the HLA's? I've also read somewhere that you can let the thing run for about 1 hour to get oil back in there? Can anyone confirm if this is true? The engine sounds terrible and I don't want to damage it, but I'd also like to avoid pulling it again as I've just put it back in.
