Snap one of the old rings and use the square end to scrape it out...

Be carefull, I've cut my fingers whilst using old rings as scrapers...

Maybe it's time to think about going to a dry sump. :)

Danny you can use a broken ring to clean the grooves. Be real carefull not
to gouge the alum. I've soaked pistons in a carb cleaner bucket for a week
and they come out looking new. (if you're not in a hurry)
There's tons of hint's/tips/advice. #1 is making sure the block is clean.
I usually take it to a shop for a hot washing. I feel that cleaning it in a
water-based parts washer is no more effective than peeing on it... Clean
the threaded holes with pipe cleaners and solvent when you get it back.
Test the crank with Plastigage. Make sure the crank passages are clean.

I loop a chunk of hose around the crank and stick it onto the rod bolts when
inserting the pistons. It will guide the rod and keep it from scratching
the cylinder and crank.

Be doggon sure you have the bearings in correctly with oil passages open!
I like to insert thrust bearings after the crank is in place and rotate them
around the crank. Just don't forget!

Check the ring end gap!!!!

Don't use a gasket on the oil pump. Just sealer. I like the grey stuff.
Never blue.

Put the oil squirters back in while the pistons are out!

Watch how tight you make the long alternator bolt. It goes through the oil
pump. When I used a gasket on the pump the bolt would torque the pump
sideways a bit.

Watch where the drain hole is behind the oil pump front seal. Be sure you
get the seal back far enough to clear the front pulley but not back enough
to block the oil return. Perfectly flat is usually good.

This won't help you for tomorrow night, sorry. I remember
someone mentioning that Mazda has a shop manual that
specifically addresses building the 1.6 or 1.8 Miata engine in
more detail than the standard Mazda SM. I searched miataforum
for reference to it, without luck.

Anyone know of this manual, or am I starting to lose my memory!?

Danny,

Go to Autozone and rent a piston ring scraper tool.
It will remove all the gunk from the ring grooves. Or
you can break an old ring in half and use the edge to
clean out the groove. Be careful not to slip and
scrape!

Good luck,
Chris

There are 3 manuals, one basic shop, one motor, and one electrical.

When I was at Kelly AFB they had blind civilians checking turbine blades
because they could feel things that nobody else could see. I like to check
both side of bearings and both surfaces they mate to with clean fingers
(except for assembly lube) as they are installed. You don't want /anything/
between the bearing and what's on either side of it.

Have come to the conclusion that the one single thing you don't bother
checking is the thing that's going to be wrong. Check all clearances. I
check a ring in every cylinder. Be /sure/ they didn't sell you the wrong
size rings in the correct box.
