Narrative:
I was involved in an oil breather pressure test on a B737-200 type aircraft, that had JT8D engines. After the test was completed, the aircraft was to be taxied back to the gate. A mechanic started closing the cowlings. At this time I told him that I did not want the cowls closed due to the pressure gauge still being in place. At this time I was informed that the mechanic taxiing the aircraft wanted them closed, and I was also told that the gauge could be removed from the oil service door, and I agreed that it could be done that way. After returning to the gate, there was a push trying to get paperwork done for the aircraft's departure. It was at this time that the pressure gauge was overlooked. I had put the original oil cap in the test gauge box, in back of my truck, as a reminder, but the truck was gone when we returned. There was no oil loss due to this accident. The gauge was found at the next station and removed.

Title: A B737-200 WAS DISPATCHED WITH A PRESSURE GAUGE USED FOR TROUBLESHOOTING ATTACHED TO THE ENG BUT UNDER THE ENG COWLING.
Narrative: I WAS INVOLVED IN AN OIL BREATHER PRESSURE TEST ON A B737-200 TYPE ACFT, THAT HAD JT8D ENGS. AFTER THE TEST WAS COMPLETED, THE ACFT WAS TO BE TAXIED BACK TO THE GATE. A MECH STARTED CLOSING THE COWLINGS. AT THIS TIME I TOLD HIM THAT I DID NOT WANT THE COWLS CLOSED DUE TO THE PRESSURE GAUGE STILL BEING IN PLACE. AT THIS TIME I WAS INFORMED THAT THE MECH TAXIING THE ACFT WANTED THEM CLOSED, AND I WAS ALSO TOLD THAT THE GAUGE COULD BE REMOVED FROM THE OIL SVC DOOR, AND I AGREED THAT IT COULD BE DONE THAT WAY. AFTER RETURNING TO THE GATE, THERE WAS A PUSH TRYING TO GET PAPERWORK DONE FOR THE ACFT'S DEP. IT WAS AT THIS TIME THAT THE PRESSURE GAUGE WAS OVERLOOKED. I HAD PUT THE ORIGINAL OIL CAP IN THE TEST GAUGE BOX, IN BACK OF MY TRUCK, AS A REMINDER, BUT THE TRUCK WAS GONE WHEN WE RETURNED. THERE WAS NO OIL LOSS DUE TO THIS ACCIDENT. THE GAUGE WAS FOUND AT THE NEXT STATION AND REMOVED.
