I am stumped and hope someone can shed some light. I installed a SBC 350 that sat around for about 12 - 15 years and fired it up and had 65# of oil pressure. Everything seemed to be normal until I noticed there was no oil coming out of the rockers. I pulled the right bank pushrods and rockers to blow them out and noticed there was oil in the pushrods - most were clean. The hyd. lifters pumped up and I watched the pushrods rotate while cranking engine over. I even ran it for about 20 minutes by manually oiling the rockers to no avail. I substituted another distributor thinking the base may be too small and oil leaking by there - never started it but just cranked it and watched the rockers - nada! Doubt all the lifters went bad sitting and thought if the oil galley was blocked, at least some oil would come out of some of the rockers. Any ideas???
Thanks in advance, Stumped
