'94 Accord 208k Cylinder #3 Not Firing

  1. '94 Accord Sedan LX 208k

    Yesterday while climbing a hill I felt a loss of power and suddenly a
    lot of shaking. Prior to this the car had run smoothly, but did smoke
    blue smoke at start up. Last night I changed out the plugs. Most had
    oil on them so I changed out the valve cover and plug gaskets. The
    smoke has since stopped, but cylinder #3 is not firing. The old plug
    was black, and the new one was black too after running for a minute. I
    know the wires are good, I didn't know better and tested the voltage
    with the engine running and I think I burned my multimeter out.

    I'm pretty sure compression in #3 is fine because I accidentally
    started the car without the plug in and it sounded like a really loud
    lawn mower or helicopter.

    So now that I have run the car and fixed the gaskets, if I put a brand
    new plug in #3 will it work? And will plugs covered in the black
    carbon deposit stuff still fire, or are they toast?

    I didn't know better and tested the voltage
    ========That's how we learn.

    =========== When the car runs without a 'path' for the high voltage from
    a plug wire, the arc can travel through the distributor and wreck the
    igniter. Lets hope not. Since Hondas have no single high tension wire
    you can isolate I like to put the plugs in a stainless steel cup with
    the wires attached. I run a ground wire to the cup.
    ============== Buy yourself four new NGK plugs or clean up the dirty
    ones. You may have blazed a new trail for the spark under the
    distributor cap. How new is the cap and rotor?

    Unfortunately there is one other set of seals that likely
    are failing at this point and causing the oil to get on the
    plug tops. See discussion at

    How old are the wires and are they OEM?

    Are you using OEM plugs?

  4. There is no more oil in the plug chambers. The wires are working and
    sparking fine. Is it possible that maybe some residue from burning oil
    has clogged the injectors?

    Check the compression anyway. I think you broke a ring.
