Tappet crown- thank you for sharing the observations.
What significance does this have for the jammed-up-in-the-bucket tappet problem?
Does the crown(offset slightly?) cause the tappet to rotate rotate ? And does a little rotation prevent jamming?
Or does jamming occur if there is almost total leak-down of oil from the tappet when the car sits for a long time ? Then when you eventually restart ,the tappet has no hydraulic 'cushion' ,so it gets hammered up into the bucket ?
All WAG but it would be good to understand this issue.
