    Under load or free-revving?

    First port of call would be a new set of plugs.
    You can have any brew you want... as long as it's a Datsun / Corolla / What is that?

    take out the plugs and attack them with a wire brush, see if that helps. re gap them too.

    other option is your injectors may need a clean, but try the plugs first.

    it is definitely a blown head gasket. just chemi-weld the head and all your problems will be fine. it will even raise your compression and give you 30% more power.

    nah leads/distributor/service generally fix this. as well as a properly sealed O2 sensor

    can you get someone to rev it while you pull leads off, to try and isolate what cylinder/s it is
