Usually on hydraulic lifters you usually adjust the valves when the engine is running.
But before you start adjusting all the valves try to take up all the clearance on all the valves.
This way when you start up the engine all the valves won't be clicking at the same time.
Start the engine and you loosen the adjusting nut until it clicks then turn down and tighten the
adjusting nut until the clicking disapears, then turn in about a quarter of a turn.
Some of the old motors manuels will say one and a half turns but that's too much.
I useally go about a quarter of a turn or one half a turn in, but for me I prefer a quarter of a turn.
THE ABOVE DOES NOT APPLY IF YOU HAVE SOLID LIFTERS
