Narrative:
On jan/xa/01, we took off from lga to pbj. We had a normal takeoff. The WX that morning was IMC, with a reported visibility of 2 1/2 mi. The ceiling was approximately 1000 ft to 800 ft. As we were on vectors during the departure, and leveled at 12000 ft, we realized the #1 low oil pressure light was illuminated. I (the first officer) was the PF. The captain opened the QRH and started to read and do the procedure. When he finished the low oil pressure procedure, and after commanded by the QRH to follow with an engine shutdown, he took over the controls of the aircraft, and I continued with the rest of QRH checklists, shut down and single engine approach and landing. At that time, we declared an emergency and returned to lga. We landed and stopped normally and without any further problems. Then we taxied to the gate and the passenger walked into the terminal uneventfully. Callback conversation with reporter revealed the following information: the reporter stated the cause of the loss of #1 engine oil pressure and quantity is unknown as maintenance made no report to the crew. The reporter said a visual check of the engine on the ground revealed heavy pooling of oil in the tailpipe.

Title: A B737-200 ON LEVELOFF AT 12000 FT DECLARED AN EMER AND DIVERTED DUE TO LOSS OF #1 ENG OIL PRESSURE AND QUANTITY. CAUSE UNKNOWN.
Narrative: ON JAN/XA/01, WE TOOK OFF FROM LGA TO PBJ. WE HAD A NORMAL TKOF. THE WX THAT MORNING WAS IMC, WITH A RPTED VISIBILITY OF 2 1/2 MI. THE CEILING WAS APPROX 1000 FT TO 800 FT. AS WE WERE ON VECTORS DURING THE DEP, AND LEVELED AT 12000 FT, WE REALIZED THE #1 LOW OIL PRESSURE LIGHT WAS ILLUMINATED. I (THE FO) WAS THE PF. THE CAPT OPENED THE QRH AND STARTED TO READ AND DO THE PROC. WHEN HE FINISHED THE LOW OIL PRESSURE PROC, AND AFTER COMMANDED BY THE QRH TO FOLLOW WITH AN ENG SHUTDOWN, HE TOOK OVER THE CTLS OF THE ACFT, AND I CONTINUED WITH THE REST OF QRH CHKLISTS, SHUT DOWN AND SINGLE ENG APCH AND LNDG. AT THAT TIME, WE DECLARED AN EMER AND RETURNED TO LGA. WE LANDED AND STOPPED NORMALLY AND WITHOUT ANY FURTHER PROBS. THEN WE TAXIED TO THE GATE AND THE PAX WALKED INTO THE TERMINAL UNEVENTFULLY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE CAUSE OF THE LOSS OF #1 ENG OIL PRESSURE AND QUANTITY IS UNKNOWN AS MAINT MADE NO RPT TO THE CREW. THE RPTR SAID A VISUAL CHK OF THE ENG ON THE GND REVEALED HVY POOLING OF OIL IN THE TAILPIPE.
