    A few cylinder block questions

    When honing the cylinders should you be able to physically feel the scratches with your finger nail?
    I literally run the hone up and down for just a few seconds with plenty of oil but the cross hatching scratches i can feel with my fingernail which doesnt seem right?
    Apparently the duratec uses cast iron liners which i assume is softer than steel.

    I have also caught the deck of the block scratching the surface slightly around what i assume is an oil return from the head and a head bolt hole.
    Should i get the deck lightly skimmed or leave it and hope for the best?

    I don’t go feeling them with a nail but I wouldn’t expect to feel them or barely at all. did you use a 3 leg hone or a flex hone? From what I can see on my phone Oil way will be fine
