Am going to start it back up without the cover as suggested. However, I was thinking about this:
The head is a 235 head (3835913) and the old rocker arm assembly used the drip tube affair for lubrication. I installed annular solid lifters so the oil could run through the lifter galley and then up to the head. However, the new rocker arm assembly I used was a later version (1959 on I think) where the grooves in the rockers themselves are offset and the shaft was meant to be fed via a center ring with a direct feed from the full flow oil system. Could I be having a problem by using the older drip style oil lubricator with the newer style rocker assembly? Seems like I read something about this once.
