Narrative:
I met aircraft inbound and was informed by first officer that the #2 engine oil access door was open. I asked baggage handlers if they opened it and they had not. I proceeded to close and latch the door and the door seemed to close normally. I notified my lead and asked for a reference to secure door in case it opened again in-flight. He provided me with a reference for securing servicing doors with tape; maintenance manual 20-80-00-201 step 5b1&2. I contacted maintenance control and informed them of the issue and gave them the reference and they agreed it was correct. I secured the door and installed a deferral to fix door in 25 flight hours; and to re-inspect for security of speed tape prior to each flight. Later on; I was informed that there may be a discrepancy that the oil tank access door provides pressure relief; maintenance manual 71-11-05. The discrepancy that may have taken place is per maintenance manual 20-80-00-201 blowout panels cannot be taped.
