    I had a chugging motion in my vehicle the other day, and discovered
    from a code reader that it was something to do with my second
    cylinder. I looked in the spark plug, and there were massive amounts
    of oil in and around the spark plug threads. I'm also burning oil like
    a sieve but there are no leaks below the car. Any ideas?

    If there's oil on the threads, I'd suspect the valve cover is leaking. Is
    this a 12 valve or 16 valve engine?

    What code did your receive?

    What did the electrodes of the spark plug look like? Was there a large
    amount of oil on the electrodes as well, or was it dry and carbony?

    To be honest, I'm not sure. And the code was.... it was the one for
    the cylinder 2 misfire (I'm sure if you put the code down here I'd
    recognize it). As for the electrodes, they were fine, same with the
    spacing. Oil was only on the threads.

    The 16V engine has the plugs in holes in the center of the valve cover.
    The 12V engine has the spark plugs in the front side of the head.

    Since the oil is only on the threads, you should look for external sources
    of oil such as the valve cover gasket. On the 16V engine, this could soak
    the wire boot and contribute to a misfire. If you have no oil damage to
    the wires, you should probably proceed with the first steps of otherwise
    normal misfire diagnosis (checking plugs, wires, coil). Since you have
    P0302, concentrate primarily on the components of the #2 cylinder. If you
    don't find anything conclusive, you can try switching plugs, wires (if
    they'll reach), or coils with another cylinder to see if the misfire moves
    to the other cylinder.

    Just as an update, I took it to Hyundai today, and they said the
    cylinder itself, plus the other 3 cylinders are basically on their way
    out the door, so I'd have to redo the engine, something I'm not
    willing to do or pay for. But the car is a 12V engine, and there was
    no oil damage on the wires.

    I agree with your determination. It isn't worth spending that kind of
    money on a 12 year old car.

    On the other hand, it's possible that if you drop a new set of plugs in it
    that it'll run well for a while until the plugs get oil fouled again.
