Narrative:

With the bleed xfer. After departure from ZZZ we got a strong odor in the cockpit. The odor did not dissipate and after a short period of time we were experiencing headaches and burning eyes. We isolated the problem in the #1 engine bleed and pack (unknown exact as we closed both valves). Continued the flight at FL240. A maintenance write-up was completed and maintenance in ZZZ1 was notified. Callback conversation with reporter revealed the following information: the reporter stated the cause of the strong odor was isolated to the #1 engine but the exact component failure is unknown. This was not the first flight of the day and was not related to the bearing seal leakage on newer engines with overnight layovers. But the strong odor was hot oil on hot ducting.
