i dont know much about how an engine works, but i'm guessing if there was oil in there that the oil prevented there being a spark which was supposed to ignite the fuel. but since there wasnt a spark, the fuel remains.

i'm not saying for sure that this is what happened, but i'm just trying to help.

Sounds like you need to replace the large o-ring gaskets that prevent oil from the valve train from entering where the spark plugs are.

I might have misunderstood what you said. Was the oil on the spark plug tips (meaning oil in the combustion chamber) or was oil on the other end (which is what I assumed)?

Well it must be on the plug wire side cause 2 of the plugs were so flooded with oil/gas you couldnt see them when the plug wire was pulled off it an oil was dripping of my plug wire.

Unless there is some weird crack in the valve cover, the only way oil could get into the spark plug tube is through those o-rings. If they are new, then they are not seated properly or maybe pinched. I personally can't imagine how gasoline could get into the spark plug tube.

Yes.

I don't know about the distributor off the top of my head. You'll need to check the FSM or Haynes, etc. if you have one.

Just unscrew the two screws (speaking of FWD version, not sure about RWD dists since I don't own one), pull the cover off the distributer, do NOT disconnect the plug wires as you will be hating yourself when you try to plug them back in in the right order, then look at the 4 points on the inside of the cap, also check for cracks. If they're blackened really badly or there is a crack on the inside or outside of the cap, it's bad...if in doubt just replace it. Underneath the cap and still attached to the other half of the distributor is the rotor, it looks like a small blade with, what will appear, to be carbon sandwiched in the middle. If this is blackened or if the piece that the rotor is attached to is discolored or cracked (it should be spotlessly clean) then it's bad too or like I said above..if in doubt, just replace it. When you put the cover back on, don't overtighten as it'll crack the distributor cap. Don't forget to unplug the negative terminal first (paranoia)...if for any reason power is active you'll get a marvelous jolt from the rotor, heh

I believe he asked how to check if the "distributor" is bad, not the cap and rotor.

Re: Gas on my spark plugs?

had *** same problem, first 2 plugs drenched, but they were drenched from the threads down onto the part where it sparks. changed the "O" seals and rocker gasket, still didnt fire up, checked for spark, no spark. checked all fuses, all good, but there is a relay noise comin from the big black fusebox on the passenger side of the engine bay when i try to crank it. took the cap off my friends distributor (has same car and year as me) put it on mine, his rotor looked to be in a condition similar to mine, still nothin, checked to see if voltage was comin from the two connections goin into the distributor and there was, which leads me to believe a totaly fried dizzy. if i put a new one on this and it doesnt work, should i look to a new ecu possibly?

I Love Lamp.
