The code partially is "stamped" on the head.

I'm not sure but you may need to check the engine.
Check Auto Zone or Advance Auto, the codes are online.
To check the OBD on a 1991 Mazda 929, you'll need to locate the diagnostic connector, which is typically found under the dashboard near the driver's side. Use a jumper wire to connect terminals 1 and 2 on the connector to put the car into diagnostic mode. Turn the ignition key to the "on" position (without starting the engine), and the check engine light will flash to indicate any trouble codes stored in the system. Count the flashes to interpret the codes, which can then be cross-referenced with a service manual for further diagnosis.
Go to www.banzai-racing.com , it will tell you how to get the error codes and what they are.

The 1991 Mazda 2600i pickup does not have a standard OBD-II port, as it predates OBD-II regulations. Instead, it uses an earlier diagnostic system, typically accessed through a connector located under the dashboard. To check for trouble codes, you'll need to use a specific diagnostic tool or jumper wire to connect certain terminals on the diagnostic connector, then turn the ignition to the "on" position. This will trigger the check engine light to flash codes that indicate any existing issues.
To reset the check engine light on a 1991 Nissan pickup, you can disconnect the negative terminal of the battery for about 10-15 minutes, which will clear the engine codes. After reconnecting, the check engine light should go off. Alternatively, you can also use an OBD-I scanner to clear the codes, if you have access to one. Make sure to address any underlying issues that triggered the light before resetting.

My 1991 Mazda 323 has two plastic screws on drivers side, facing engine. Are they airbleeder valves?
There is nothing to "check". Look in the owners manual and change the belt according to the service requirements. They never "look" bad until they fail and destroy the engine.
