i have a 04 manual 35DE

this morning i went to crank the car, got a clanking sound from the engine, it cranked, the sound died down, oil pressure was normal, started above 70-90 then warmed up and went to <60, so i gave the gas a tap, and the rpm went up, then drop down and the car died, i checked the dip stick, the oil was all over it, wipe it off, stuck it back in, same thing, oil wayyy high on the stick, now if i crank it, and let it sit, the rpm will slowly drop pass 1k to 500 and then dies, no weird smells, no lights, the clanking sound even went away. but the rpm still drops, anyone have any idea, thank you very much.
