    Cracked head new head installed now coolant drips from number 1 steady drip on the inside of liner starts as soon as coolant is filled above the head. Where do I look if the grommets appear intact?

    No it’s running down the inside of the liner. I’m leaning towards a bad head.

    What did the straight edge tell you when you had the head off?

    Leaking that bad it should be obvious
