    Default DS oil in spark plug tube

    Got a fair wack of oil in number 4 plug hole, could there be a hair line crack in the metal tubes, as i cant see how oil can get in there as the tube protrudes above the rocker cover, anyone had any experience with this issue?

    The tappet cover seal plug is likely leaking.
    Ever removed a tappet cover? Reckon you will now.

    There is a round seal for each plug hole, the tappet cover gasket is probably as hard as a goats forehead, worth changing it too.

    Hope this helps.

    I just replaced all 4 seals on my car. One of them was cracked and there was oil in the tube. When I replaced the tappett cover and screwed it down two of the news seals split! When the engine was running, with the spark plug cover removed you could see oil spitting up the tube. I didn't do it up that tightly but be careful.

    Some times the metal tube is not an oil tight fit in the cast aluminium of the head. IT CAN LEAK AT THIS POINT. If the seals on the rocker cover are leaking it is more likely that the oil will be seen on the rocker cover rather than fill up the sparking plug tube. If the tube is loose it is an easy job to remove it, clean the head where it sits and reinsert it with some silicone sealant or Loctite!
    Cheers Gerry

    Is it possible to source just these seals as opposed to a complete top end gasket set?

    Yes, Roger Parker supplied me with the 4 round seals, and a rocker cover gasket. Four new, and not oil soaked, tubes too. Cheers.

    Yes, they are readily available from most suppliers.
