THE PLT STATED THAT THE ENG BEGAN TO RUN ROUGH DURING FLT, THEN ALL AT ONCE, IT STARTED VIBRATING EXCESSIVELY. HE ATTEMPTED TO LAND AT THE PHILLIPS AAF, BUT THE ARPT WAS CLOSED & THE RWY LIGHTS WERE NOT ILLUMINATED. BY THE TIME HE SAW THE RWY, THE ACFT WAS NOT IN A POSITION TO LAND, SO HE TRIED MANEUVERING TOWARD AN OPEN AREA ON THE ARPT. HOWEVER, THE ACFT COLLIDED WITH TREES & CRASHED. AN EXAM OF THE ENG REVEALED THAT THE #3 EXHAUST VALVE PUSHROD WAS BENT & THE #1 INTAKE VALVE WAS BROKEN. AFTER THIS ACCIDENT, THE OWNER/OPERATOR (CAP) STOPPED USING PHILLIPS XC2 ENG OIL DUE TO POSSIBLE PROBLEMS ASSOCIATED WITH ITS USE WHICH INCLUDED STICKING VALVES.
