Narrative:
As we departed ZZZ we got a very strong oil smell of burning oil as we transferred to the engine bleeds from the APU bleeds. It was strong enough to burn my eyes and it gave the first officer and myself a slight headache. The flight attendant could smell it; too. We had been smelling it all day. However; it dissipated pretty completely after about 15 minutes. This last leg seemed stronger to me and my eyes had not burned prior to this last leg.callback conversation with reporter revealed the following information: the reporter stated the airplane was flown two legs and both times when switching pneumatic bleed sources from the auxiliary power to engine bleeds; they had the strong oil burning smell. The reporter said he is not convinced it is primarily an auxiliary power unit oil seal problem but may be an engine oil seal problem.

Narrative: AS WE DEPARTED ZZZ WE GOT A VERY STRONG OIL SMELL OF BURNING OIL AS WE TRANSFERRED TO THE ENG BLEEDS FROM THE APU BLEEDS. IT WAS STRONG ENOUGH TO BURN MY EYES AND IT GAVE THE FO AND MYSELF A SLIGHT HEADACHE. THE FLT ATTENDANT COULD SMELL IT; TOO. WE HAD BEEN SMELLING IT ALL DAY. HOWEVER; IT DISSIPATED PRETTY COMPLETELY AFTER ABOUT 15 MINUTES. THIS LAST LEG SEEMED STRONGER TO ME AND MY EYES HAD NOT BURNED PRIOR TO THIS LAST LEG.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE AIRPLANE WAS FLOWN TWO LEGS AND BOTH TIMES WHEN SWITCHING PNEUMATIC BLEED SOURCES FROM THE AUXILIARY POWER TO ENG BLEEDS; THEY HAD THE STRONG OIL BURNING SMELL. THE RPTR SAID HE IS NOT CONVINCED IT IS PRIMARILY AN AUXILIARY POWER UNIT OIL SEAL PROBLEM BUT MAY BE AN ENG OIL SEAL PROBLEM.
