I found on my truck the rocker arm shaft plugged up with sludge. After taking it apart and cleaning everything and cleaning out the oil feed in the heads. The rockers are now getting oil. After the engine warmed up to normal operating temperature I adjusted the valves. Been running great with a quiet valve train (as quiet at a mechanical lifters can be) compare to before.
