|J. Schwiebert said: (quoted from post at 15:45:39 01/31/13) Have an early 1970's GMC truck in the shop. It had bent push rods on one side. It was a repeat problem. We put the new push rods in and started the truck, runs good now BUT the side with the bent push rods does not have near as much oil going to the rocker arms as the other side. Question how do the rocker arms on each side oil and if it is metered where is it metered? We have an older Truck manual but no schematic of the oiling system. Thanks in advance for any help/ Any one have a GMC shop manual that could maybe copy some pages? J.|
John, I just coped this from a Motor Truck Repair Manual. If you'd like more, let me know.
Sorry, I got it upside down.
Try this again.
