Just an update: It does seem that the one engine bolt does have a channel in it for the oil to flow through.

I took out the bolt, cleaned the channel with pipe cleaners and re-installed the bolt. I also blew out the rocker arm assembly to find only 2 rockers were plugged.

Anyway, I have to try the Marvel Mystery Oil trick as I used that to clean out the channel.

BTW: I have 35 to 40 lbs of oil pressure so at least that is working!

Hope for the best.
