I Don't Like Palnuts

[Mart]

As this has turned into a Y block discussion. Shortly after getting the motor running in my T-Bird (57 312) I had the rocker oiling issue on one side. All the passages were clear. The problem was the cam bearings. The oil passes around a groove in the cam. My bearings were worn to the depth of the groove, effectively stopping the oil from passing around the cam to the one side. I tore it down and replaced the cam bearings. All good ever since.
