Oil in cylider 1994 Toyota Corolla
Sounds like you might have a plugged up fuel filter or your fuel pump might be going bad.
As far as oil in one cylinder, it could be you have a bad valve guide, but I doubt it cause they usally all would start going bad together, you might have bad piston rings, the best thing to do is a compresion check with a tablespoon of oil in that cylinder. Check the cylinder first without oil and see what your pressure is shoud be (100-125) if lower than that, put the oil in and check again, if the pressure comes up considerably to the 100-125 then you have bad piston rings. If not than it is your valves/valve guides.
