What was found
THERE WAS A DIRTY SOCK SMELL ON TAKEOFF AND WE ARE WORRIED THAT IT COULD BE ENGINE OIL FROM THE BLEED SYSTEM. THE SMELL DISSIPATED GOING THROUGH ABOUT 10,000 FT, AND THEN WE NOTICED IT AGAIN ON APPROACH BUT NOT AS STRONG. PERFORMED HIGH POWER ENGINE RUN ON E1 AND E2 IAW FIM 21-20-00-810-803-A. NO DEFECTS OR ODORS NOTED. OPS CHECK GOOD.
