## Discrepancy

(CAN) "STRANGE" VIBRATION WAS NOTICED BY THE PILOT IN FLIGHT ALONG WITH A LOT OF GRAY COLORED OIL LEAKING FROM THE PUSH ROD HSG TUBES.  REF RPM CHECK WAS FOUND TO BE LOW AND A COMPRESSON TEST WAS DONE AND FOUND TO BE 8/80 PSI UPON CLOSER INSP.   IT WAS FOUND THAT THE HEAD OF THE CYL WAS ACTUALLY SPLITTING FROM THE BARREL.
