A B767-300 WAS DISPATCHED IN NON COMPLIANCE WITH THE INCORRECT #2 ENG PNEUMATIC BLEED VALVE RENDERED INOP PER THE MEL.

Narrative

I PLACARDED THE #2 ENG HPSOV (HIGH PRESSURE PNEUMATIC SHUTOFF VALVE) PER MEL 36-02B. I ACCOMPLISHED MPM 36-02B. HOWEVER; I INADVERTENTLY USED FIGURE 202 INSTEAD OF FIGURE 203. CONSEQUENTLY I DEACTIVATED THE WRONG VALVE. SUPPLEMENTAL INFO FROM ACN 563780: ON THE GND I INITIALLY QUESTIONED APPROX 5 DIFFERENT MECHS REGARDING R ENG HPSOV (HIGH PRESSURE PNEUMATIC SHUTOFF VALVE) AND 3602B MPM 36-2 FOR B767. ADDITIONALLY; I QUESTIONED MAINT REGARDING AN EICAS MESSAGE; 'R ENG BLEED OFF;' THAT SHOULD NOT BE DISPLAYED. MAINT REPLIED IT WAS A NUISANCE MESSAGE THAT WOULD GO AWAY AFTER CRUISE AND HIGH PWR SETTINGS. THE FO AND I DISCUSSED MY CONCERN REGARDING MAINT AND AS A PRECAUTION; WE OPERATED APU FOR TKOF TO PROTECT THE ADP. ON CLBOUT; WE SHUT DOWN THE APU AND RECEIVED 'R ENG BLEED OFF' EICAS MESSAGE. AT THIS POINT; I MADE CONTACT WITH DISPATCH AND 3-WAY ZZZ2 MAINT. I RELAYED TO DISPATCH THE MAINT ACTION TAKEN HAD REDUCED US TO A 1 PACK OP AND WE DISCUSSED MY REF TO QRH REGARDING THE 'R ENG BLEED OFF' EICAS MESSAGE. DISPATCH IN ZZZ2 CONFIRMED WRONG MAINT PROC APPLIED. DISPATCH CONCURRED THAT WE WERE FLT PLANNED AT FL350 AND WOULD REMAIN WITHIN 60 MINS OF AN ARPT ALONG OUR PLANNED RTE OF FLT. HOWEVER; ULTIMATELY DUE TO TSTMS; POSSIBLE ICING CONDITIONS; AND NIGHT IMC; I ELECTED TO DIVERT TO ZZZ3 TO HAVE PROPER MAINT PROC APPLIED. AS PRECAUTION FOR ADP PROTECTION APU WAS OPERATED FOR LNDG.
