I am new to the mazda's. I just bought a 2002 mazda 626 with a 2.5l v6. I bought it from my work (a locale ford dealer)who took it in on trade. The engine was making a noise that one of the other techs thought was a lower engine noise he removed the engine and started to tear it down and the sales manager decided it to much to replace the engine. I was wondering if there was a place to gety a service manual for this engine or what other engine would interchange. Is the bottom end of this engine the same as the earlyier models.The engine from the car has been partially disassmbled and I was unshure if the bolt were of the torque to yield like ford uses. Any information would help. thanks jeremy
