SO- update to my engine... i started to hear this tapping noise... coming from somewhere in the back of the engine. at first assumed it was lifters, then thought it wasn't. i racked my brain thinking of what it could be. me any my wife and room mate listened to it, and the problem seemed to happen at 15-2000 rpm, not at idle or just above. we determined that i must not have tightened the rod nuts or something. that could be be only problem.
so i took the oil pan off and the girdle thing with the oil pickup tube on it and low and behold... the nuts were all tight. phew i thought.. i did remember to tighten them. looked in the oil pan and it looked like a tube of glitter. oh shit there's something going wrong. metal shavings in the pan. took the rod caps off and # 3 and 4 were fucked! all sorts of grooved. guess i didn't clean them good enough before i put them back together. well i'm paying for it now. going to get a new crank, or have mine machined down and get oversize bearings.
dammit.
so i'm thinking full performance mazda..... if i gotta tear it apart again, i wanna bore it out and get new pistons, cam, valves, maybe a b2000 head, mechanical lifters, balanced rotating assembly and port/polish. dunno yet, it all depends on machine shop cost and parts cost. it is my every-other-day-ly driver after all and it needs to be up and running soon. if you guys know of any cheap parts as mentioned lemme know!!!
