  • Condensation on the spark plugs

    Ive just noticed when the engine cooled there is some minute water droplets on the spark plugs, i pulled the head off expecting a blown head gasket, but all is good.
    I straight edged the head and block and they seem fine
    Were else should i be looking
    Its a 302 yamato
    Thanks

      Exhaust cover and gasket, check exhaust cover with a strait edge.

        Hey Ric, will an exhaust tuner not sealing the bottom of the powerhead scavenge water too?

        Also check you plugs, if the insulators are white, like very clean, they're definitely getting water in cylinders while running
