Default tick tick tick TICKING VALVES

Pretty much what title says.

Lately I've been noticing some fairly loud valve tick. Motor was rebuilt 6 or so months ago, after which it ran like an absolute champ and gave me no problems of any kind.

Didn't do anything to it to or changed anything up. Just installed the current turbo setup, and replaced a leaky valve cover gasket. Last few times I fired it up and had it sitting there it was super obvious: VERY loud ticking at idle.

I'm going to change the oil because its around 3k alredy, is this oil related and should I change to something that will prevent or help the ticking quiet down?

I'm on mobil1 full synthetic.

Been reading hustlers review of rotella and sounds like its pretty good. Had some decent results with royal purple in the past. Any input on this?

Anything I should be worried about?
Engine sounds and looks healthy otherwise.

Level is right in the middle of the two marks.

But yes, I'll definitely change oil. (its about time anyway)

I've noticed a loud tick showing up in mne also. Normally shows up when I first start and goes away in a few seconds. Yesterday started it and it was a lot louder and lasted a lot longer. I had just run about 40miles on the interstate at 80+ mph. Seems to get worse after running the engine a little harder. I have full syn 10w30 next change I'm switching to 5w30. /hijack

I'm an oil n00b: what do you plan to accomplish with this?
Thinner oil will get rid of the ticking?

Nothing. MMeador has a '97 so the HLA are compressed, the only real solution is removing them, taking them apart and cleaning them out. fooling around with oil weights and ATF and **** does nothing.

seriously, this is miata 101.

Ok then, last stupid question I promise
Aside from sounding like ****, is there any damage or adverse effects to my engine from them ticking like that?

If not then I don't give a **** and they can tick all they want

you have shim over buckets right? so you're low on oil or your lifters need adjustment. the ticking noise is the lifters hitting the camshaft.

101? Crap I am in the wrong class! I'm still in miata 93. My advisor said I needed to start in remidial classes first.

Thanks, good to know about the oil weights and common HLA problem! May look into the cleaning when it's parked for the winter.

Might be easier also, just a suggestion, to switch to a '99 head. I hear they don't have that HLA BS.

Then get off with thy valve cover, and unto the lifter surface with thee and thine feeler gauges be you!

If the problem is going away with a slight bit of runtime I wouldn't think it would be anything worn out... Might just be my thought though. As my old B6-ZE used to sound like an old diesel pickup truck upon starting up. Upon re-reading, disregard my post...

Did your rebuild include recut valve seats? Pop the cover off and check the clearances. Your machine shop may have screwed up.

The head was never touched. Car/engine has 60k miles on it and head looked mint, so I didn't do any headwork whatsoever.

The ticking will be from one of two things - valve shim out of adjustment or lack of oiling. Like Joe said: break out the feeler gauge. Is there any reason to believe that you may have a blocked oil passage?
