A hydraulic lifter that ticks during a cold start and then stops after the engine is warmed up is loosing its pressure when the car is turned off. Because of this that rocker arm has too much slap causing the tick. I drove a truck five years with a ticking lifter. It was still running good when I got rid of it.
What oil are you running? If you go to an oil that flows better during a cold start such as 0w20 or 0w30 the lifter will pump up faster.
