I was searching youtube last night for Mazda stuff and stumbled on a 12 part vid on rebuilding a 12a.Dude must of worked for Mazda or something but damm it looked so easy.He did it on a picnic table and a coffee can.Whats weird he didnt use no special tools.Only problem he had was putting the middle housing on and lining up the oil pump.If its like that i wanna try it.

provided hes checked all clearances.. slappin her together is not rocket science

post the link..

i dont know how to post links,im not to bright when it comes to that stuff,Just type rotary rebuild and you will find it.Its like 12 parts or so.
