I've got a Ford 360 been rebuilt by someone else, started and ran good a few days maybe 1000 miles now one push rod came off the rocker and one pushrod bent and broke. Solid lifters and soild pushrods. 20 plus psi oil pressure at idle. But I have no oil coming to top of engine. What's wrong? I thought the oil traveled thru the pushrods and lifters to get up top. (obliously not the case with solid ) the cylinders involved are 1 and 8.
