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.

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.

i say:
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.

why diesel lubes? what's the composition difference?

We went through this a few months ago. I'm much too lazy to do it again.

Well, once it fianally STOPS snowing I'll pull of the valve cover and have
a look. I have a Supra I use in the summer, the Mazda's a winter beater.
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...

I did a little research on this Mike.

" On the other side of the engine block are those additives which will
cleanse your engine, not coat it. Stuff like Bardahl, Rislone and Marvel
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
contact".

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...
