Just a quick update, took new oil pump apart, cleaned out machine oil, made sure no trash. Packed with petroleum jelly, filled new filter all the way and installed. Left valve covers off. Turned over motor 8-10 seconds with dist unplugged. hooked back up, motor fired right up, oil light went out 3-5 seconds, all push rods flowing oil. Shut off, replaced covers, restarted. Ran several minutes finally all lifters quieted down! Starts right up first crank like before, now going to change oil and filter again, put fresh Amsoil and wix gold filter back. Thanks for all the input, advise and past experience pointers. Havent got to drive it since last thanksgiving, back in the saddle again! Again Thanks guys.
