## Discrepancy

ON INITIAL CLIMB OUT AT APPROX 300 AGL, NOTICED AN ODOR IN COCKPIT.  ODOR WAS SLIGHTLY OILY & HAD A BURNT NOTE TO IT. DID NOT SMELL ENTIRELY UNPLEASANT, BUT WAS QUITE STRONG. RAN QRH FOR ENVIRON ODOR & DURING PROCEDURE NOTICED THE ODOR WAS WORSE WHEN LT PRESSURE SOURCE SELECTED. FLIGHT DIVERTED, RT PRESSURE SOURCE SELECTED & ODOR STILL PRESENT.   ACCOMPLISHED TROUBLE SHOOTING OF SMELL IN THE COCKPIT ON LT ENGINE.  PER PWC RECOMMENDATION, LT ENGINE REMOVED   DUE TO SMELL IN THE COCKPIT. INSTALLED REPAIRED ENG IN LH POSITION OF AIRCRAFT. PERFORMED POST INSTALLATION IDLE LEAK & OPERATIONAL CHECKS AS WELL AS CALIBRATION RUNS, NO DEFECTS.  ODOR IS NO LONGER PRESENT WITHIN THE COCKPIT OR CABIN.
