Boeing 757-236, G-CPET
After takeoff, the flight crew detected a transient oily smell in the cockpit and, later in the flight, began to feel unwell. They donned oxygen masks and declared a ‘PAN’ in accordance with the published emergency procedure, after which their condition improved. The cause of the incident was determined to be an oil leak from the left engine, which allowed oil fumes to enter the bleed air/air conditioning system and thence the cockpit air supply.
