It's not really a 'lifter', as I think I understand the term.
The car has an OHC, 3 valves per cylinder. They are actuated by rockers,
and at the end of each rocker is an HLA (Hydraulic Lash Adjuster). I guess
it's supposed to eliminate the need to adjust the valves by expanding or
'deflating' with oil to take up the slack. It seems they collect gunk, as
do the holes providing the oil.
It seems the MMO added to the oil has taken care of this for now. They
look fairly easy to replace. Once it comes off the road for the summer.
Sounds like the same operation as a hydraulic lifter, but located on the
other end of the rocker arm. Lifters deflate in pretty much the same way,
but I don't know if it is usually that they stick "down" or if they leak too
badly to work.
Your plan to tackle it when more convenient sounds good to me. At least a
collapsed HLA (almost wrote "lifter") won't strand you anywhere.

When the Supra goes on the road I plan on giving the Mazda a better going
over than I did in December when I bought it. But the forecast is for more
snow this week.
And the funny thing is, I drove it about 20 miles yesterday, no problem.
This afternoon it fired up just fine, I drove it about 7 miles and the
ticking came back. I stopped for a cup of coffee, and the next three times
I started it, it ran fine.
So, I guess the cover comes off in the (real) spring...

good on you! i have a really strong opinion on anything related to oil
sales and the total lack of labeling thereof. it's all to deceive the
consumer. manufacturers all know what their competition is using - they
have labs. consumers don't, and this information vacuum is the void
into which garbage is sold. msds info like you've dug up /is/
available, but it's not exactly front and center, and even then, there's
get-outs for "proprietary" contents. the whole machine is a scam.
1. label all products, just like food and shampoo.
and while we're at it:
2. make publication of the calorie content of gasoline mandatory.
alcohol content is mandatory on beverages, calorie content is published
for natural gas. same principles should apply to gasoline.
I did a little research on this Mike.

Mystery Oil claim they can make your engine run quieter and smoother, and
reduce oil burning. These are products which contain solvents or detergents
such as kerosene, naphthalene, xylene, acetone or isopropanol. If used
properly, I suppose these products will strip off your Teflon and zinc
protective coatings! But unless you have a really old and abused car, you
probably have no need of stripping away sludge and deposits from your
engine. Thus, you probably have no need for these wonder cleaners. If you
overuse such products you can damage your engine by promoting metal to metal
This came from the following site: http://skepdic.com/slick50.html . I
couldn't find much about the contents but I would conclude that it is a
petroleum distillate solvent that removes sludge, dirt, and other corruption
thereby enhancing the oil flow but I can't prove such. I would say it is a
temporary fix for an engine that has been neglected over time...

This is your Hydraulic Lash Adjusters (HLAs) starving of oil. HLAs are
maintenance free and as soon as they start to tick they are supposed to be
replaced. Unfortunately Mazda/Ford wants an arm and a leg for them. There
is a way to squeeze some life out of them.
1. Pour some ATX oil into your engine. DO NOT USE A LOT, 300ML WILL BE
Auto transmission oil/fluid is VERY high in detergents so it will remove
most of the gunk from the HLAs and anything else that oil has contact
with. Drive on this oil mixture for a day or two, no more. 2. During an
oil change, get yourself some engine flush(readily available at any Auto
parts retailer) follow instruction on the can/bottle 3. Put new oil in.
If this procedure did not fix your HLA tick (not to be confused with injector
is normal) you ether will need to clean HLAs physically or replace them.
This procedure is not recommended for engines which have some oil
consumption, as this will clean out all the gunk in piston rings as well,
and you might end up using more oil and smoke badly too
I was approaching an oil change anyway. I wonder if adding more MMO might
have a similar effect...

Also, I will try the 'lazy man's' way suggested by another poster, ie
adding ATF or Marvel Oil before the next oil change. It was due in 500
more miles anyway, so I'll try 'flushing' it and see what happens. One
method suggests simply sliding the rockers and pulling the HLAs out and
cleaning them, another prescribes removing the rocker cams and arms and a
thorough cleaning. Since the car is so clean, I will probably do this
after I park it for the summer!

I agree. Once a lifter becomes noisy, it's time to bite the bullet and
replace 'em all.
Regarding "fitting to the cam," well that's another issue nowadays since
modern motor oils tend not to support good lubrication of direct
contact engine parts (also due to EPA restrictions). So far, diesel
rated lubricants still have the additives to prevent wear on direct
contact engine components.
Roller lifters available for vintage cars including Honda anyone?

You can replace them without removing the rocker shafts, but I have seen a
couple write ups that say they don't go bad for no reason, and the reason
is usually that the holes that feed the oil to the HLAs are plugged. So,
it is possible to clean the HLAs and the holes feeding them oil.
I guess I'll investigate when I park the Mazda and put the Supra on the
