Pushrod oiling/heat?
On some builds from years ago using roller cams and Crane Golds.......
Those rockers had neither feed hole intersecting the groove, and on several occasions it resulted in a situation that looked like what you’re experiencing.
I was able to get it to work by grinding a very small channel that connected the feed hole to the groove.
Nothing big....... just enough to connect the pushrod feed hole to the groove.
This is a Crane Gold intake rocker with the .290 offset:
As delivered, the oil has to squeeze between the body and the shaft to oil the pushrod, and sometimes that’s not enough oil to keep from burning up parts.
