Valve train noise

Fire it up. Let it idle till it warms up and noise starts, shut it off.. pull the covers...get a sheet of tin foil...wrap or around your head, jk.. lay it out and crimp it to the rail of the head so it stays in place to catch any 'oil spritz' , fancy over here, then get your adjustment tools ready and start it up and adjust them....be it loose or tighter...till the noise stops. If it doesn't...
