I have a Pontiac 400 and I have one valve that appears to not have oil coming from the pushrod any ideas? Today I removed the valve cover and noticed that all rocker arms have oil in the rockers with the exception of the #5 exhaust valve. I am assuming that this pushrod is not flow oil as the rocker is empty. Any ideas on what would cause this? Do I need to removing the lifter or is there any other tricks that I can try before removing the intake to remove this lifter?
