having to assemble a yale/mazda d5 engine that I did not start. Lower end and pistons are already together. Have torque specs from SMH. need timing chain alignment and head torque sequence. Looks like the timing chain may be set with the crank keyway straight up and the dot on the cam pulley also straight up. Most of the engine should be easy enough. Would appreciate anything you guys can give me. alan at rrlift. net
