just my 2cents for what its worth...

You said the spark plugs were oily, i would imagion either the piston rings are worn out or the valve guides. With oil getting to the plugs your going to get a poor fire or a missfire explaining the poor sound.

Do a compression check on your cylinders and let me know what you find, hope this helps

Do a leakdown test on the 2 bad cylinders. If you get air from the crankcase, then the rings are probably shot. If you get air from the radiator, then I would suspect head gasket. We're the 2 low ones next to each other?
