    Cracked coil

    Guys, i was changing my spark plugs after 20h when i noticed the coil on middle cylinder is swollen with a 1" crack
    see pics

    Do i leave it like that or do i need to replace it?

    I also noticed top ceramic part is unusually blackened on all 3 plugs

    You will want to replace it. Once it fails, you'll be running on 2 cylinders.

    Am with Beerdart 110%.

    Take the plastic off, remove the rusty metal shield, clean it, and off ya go.

    Loads of them running like this now.

    Nah, just crack it off, it usually is, so help it on its way.
    Bend the metal sleeve out to make sure it comes off too.... and bin 'em.
