no offense goracer, but you have A LOT to learn.
and yes this must be taken into consideration when building an engine.

ok basicaly I will "only" be replacing the water o-rings and will be doing it myself because of money. So what I don't know is will the play change when reassembling the block or will it be the same? I am assuming the play is created from wear.
...yes I should be checking the specs on everything but I did "not" have any compression problems. I could have attached a 100 mile garden hose to the radiator and not worried about the o-rings again.

GoRacer don't be suprised if you have to replace more than you think. It most likely isn't going to be as simple as just replacing the water seals, you should replace all the worn down seals and other paper gaskets.

End play is a result of wear of the thrust plate and needle bearings only. So the two needle bearings, one thrust plate and spacer are the only components in the motor which determine end-play. Doesn't matter what you do with the rotors, housings and plates (as long as there is correct width clearance between rotors and aluminium housings)

Yeah, forgot to say whilst getting all technical and all that... the end play should be exactly the same if you put it back together with the same needle bearings and plate.
And don't budget on just a set of coolant rings for your rebuild!

i've been trying to perfect this on the engine
i got .005 the first try with a D spacer
then i put in a C spacer, and got .004
i think mazda says the max is .0035, and normal is .0018-.0028
what are opinions on this? how much are these spacers?

If still to much, oil a flat surface, like a piece of window glass, or a piece of end housing, or a formica counter top. lay a piece of wet or dry #400 grit paper on the oiled surface to keep the paper from moving around and oil the paper.
Measure the spacer length, and calculate how much must be removed.
Slide the spacer in a figure eight pattern on the paper for one minute. Rinse the spacer in solvent and measure again. Continue until the spacer is the correct length.
