Bumping my 2 year old thread to report lifter tick AGAIN, this time on my 2001.

I'm almost positive it is "normal" and there's nothing to worry about, but figured maybe someone had more ideas or contributions to this thread.

2001 vvt motor, with 70k miles on it. It is in FLAWLESS condition. Seriously looks like a 10k mile motor. Runs flawlessly, is clean, eats no oil, has been maintained religiously.

I have fresh 5w30 Amsoil in it now, and before that tried 10w30 Valvoline and Mobil1.

It ONLY does it at idle, and ONLY does it when completely cold. Its a fairly loud tick, and sounds like its just coming from 1 lifter or valve or whatever. Right now its esp cold so it does it often. As soon as the car runs for like 30-45 seconds, its completely fine.

So yeah.
Probably nothing?
I'll be checking and hopefully remedying tolerances when building the engine.

But in the mean time,

What do you guyths think?

My VVT engine does the same thing, for about a minute when really cold. I'm guessing just a few lifters have lash on the fat side and the cold is making it worse.

The 1.8 is a shim on top of bucket. So the valve lash is a mechanical setting, no HLA deal.

You may have .001-.003 more clearance than needed, add that to colder temps, you get tic, after the engine makes a little heat, thermal expantion happens and it quites down.

Inspecting valve clearance and changing shims is on the 60,000 mile service checklist for an NB engine.

This is from the '99-'00 FSM, but the basics apply to the VVT engine as well:

Do you guys with solid lifters check this before they start ticking, or should I only worry about this if i start hearing ticking? I'll probably check on mine before i drop the motor in just in case, BUT, I drove the donor car before pulling the motor and there was no tick whatsoever even on a cold start. I guess this is one of those things that isn't really any harder to do with the motor in the car anyways.

Thanks for the diagram Joe.

A thread from MFZ with pictures: Maintenance How-To: Check Valve Clearance/Re-shimming NB head - Miata Forumz - Mazda Miata Chat Forums Ignore all the BS in there about the dial indicator and buy a cheap micrometer off eBay.

You can do this without the SST by loosening all of the caps on the cam and letting the cam rise up off the lifters. Of course, at 70,000 miles you might as well replace the timing belt anyway, which makes it easy as you can just remove the cams entirely once the belt is off.

18: Welcome to cold start with solid lifters. I really should introduce you to my pre-emissions Ford truck. The noises it makes at startup would give you a conniption fit. I know you are just starting to get cold up there in Suckramento, so ask yourself this: Does the car continue to do this after its FULLY warmed up?

If no: Then let the car warm up for 5 minutes before you jump on it unlike what you do with your old lady when you get home from work

If yes: Time to check clearances.

It may be time to play the "stab-yourself-in-the-eye-solid-lifter-shim-game." Get a good set of feeler gauges and may god have mercy on your soul. The SST in Joes diagram is super expensive, and not needed if you have an inch/lb torque wrench. I've never actually spoken to anyone who owns one (The SST, not the torque wrench.) You just have to "get it right the first time" unless you plan to pull the cams multiple times. Change your timing belt at the same time FTW

Edit: Joes above link is WINNING! I was looking for that, but for some stupid reason thought it was on m.net

Thanks for lots of very helpful posts guys.

EO - They only tick when completely cold, like I said it completely goes away in about 30-45 seconds.

I'll check em later anyway, but for the time being I'm guessing its ok and nothing I can't postpone for another month or two.

For those with nosy HLA's, best way to clean them is to pull the inner section apart and put them in an ultrasonic cleaner. (Place them in a small jar with white spirit and hang that in the water in the ultrasonic).
You won't need to take the tiny ball and spring section apart then.
