I know that early D-Jet Manifold Pressure Sensors (MPS) were riveted together. At some point, did Bosch change over to using screws instead of rivets? If so, about when did that happen? I found pictures of both, but nothing on if/when the change occurred.
I tried searching for the answer here, but wasn't able to find anything. Thanks! |

AFAIK screws are a sign that an MPS have been opened.
If rebuilding one, not sure I would trust rivets to hold a good seal. |

They came BOTH ways from the Bosch factory. My guess is they swapped over to screws to make it easy to repair them. NO time frame for when this happened.
