Ticking Noise From Engine Due to Sticking Valve Lash Adjusters on Mazda Miata MX-5

A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

Car sits a lot, not driven regularly, valves lifters are noisy. Used to quiet after driven a couple of miles, now they don't. Added some oil conditioner (Lucas) but so far, no difference, hope lifters don't have to be replaced!

Lifter noise started after a Mazda specialist mechanic replaced my cars timing belt. He claims the lifter noise is 'normal'. Won't go back to him again. No solution yet.

I get a knocking/ticking on start up, it goes away after driving for a few miles. also it tend to choke a little upon deceleration and at idle.
