valve click

[AnthonyF]

I dont know Mazda motors that well, you might be able to do what Honda owners to which is a valve adjustment. Call Mazda and see if the procedure is capable of being done. If not, you could always take your head off (since it's not that hard on a miata) and take it to a head shop and get them to service it (go with DOVER). You will gain a lil bit of hp at the same time.


Its nothing to really worry about, but it is annoying and your valves arent getting opened to the fullest like the used to.

Hey Jesse, I'm sure Matt could tell you all about that problem. You're hearing the legendary HLA (hydraulic lash adjuster) clatter. It's caused by the lifters not getting pumped up. Assuming your oil pressure is sufficient, it usually means your oil is a bit too dirty to make it through the tiny ass passages to fill up the lifter.

Solution: change your oil a lot. I do mine every 2000 miles or so. Castrol GTX is the only oil my car likes.

As soon as my car starts clattering on a hot start (cold start will usually do it momentarily even when the oil is fresh), I'll go ahead and change the oil. Cheap way to keep the car happy and healthy.
