92 toyota camry running like on only 3 spark plugs instead of 4, oil getting on spark plugs on the passenger side seeing like black shut on the inside of hood on passenger side
Stop the oil leak. There are gaskets and seals for wherever it's leaking. Valve cover gaskets or seals on the cover if the plugs are recessed. Is the black stuff oil that gets splattered up there?
Spark plugs can keep firing even with oil around the base, but the cleaner the better. A clean engine runs a whole lot better and cooler than one caked in oil. Just don't try to pressure wash it or you'll have worse problems.
It would help you if you could isolate a non firing cylinder, find the one that's missing, I mean. There is a way to find a miss on a running engine by isolating a cylinder that doesn't drop idle speed when the plug wire to that cylinder is removed. But please have someone do it that has done it before. They will know what spark shock means, and how to avoid or mitigate it, or anticipate it-lol. Thatsa lotta voltage!
If you pull the spark plugs out, may help you find the bad cylinder: one will look quite different, may be all black and soot covered on the bottom that is inside the cylinder. Good firing spark plugs will have a tan or brown appearance down at the bottom, with very little deposits on them. (and if black and oily looking and wet, you have likely worn piston rings letting oil burn in there.) So if you could find the miss, it will help you a lot. Maybe you need a tune-up, after looking at your plugs-are they worn down real bad?
Lots of causes for a miss: ignition (plugs, wires, rotor, distributor cap, coil even), gas related (if multiport injection, possibly an injector problem) , and also an internal mechanical problem affecting that cylinder (like a bad sealing valve, a head gasket leak: do a compression test to check for that).
I hope I have helped you in some small way. Good luck.
