Hi,
The reason you have
oil on the top of the intake valves and inside your intake manifold- take your carb off and look into the manifold- lots of
oil eh?
Is because the
oil is forced up through the open intake valve during cam overlap, then sucked back down during the next intake stroke.
You need to hone and re ring the cylinders before you wreck the bearings, check the rod bearings, they will be the 1st to wear.
