Services Performed
- PERFORMED A DIAGNOSTIC SCAN. CODES PRESENT ARE P3033 & P050D. PERFORMED LIVE DATA SCAN SCAN AND FOUND AN ACTIVE MISFIRE ON CYLINDER 8. REMOVED COIL FROM CYLINDER 8 AND SWAPPED IT TO CYLINDER 6 TO SEE IF MISFIRE WOULD SWITCH TO CYLINDER 6. NO CHANGE IN MISFIRE WAS DETECTED. MISFIRE STAYED ON CYLINDER 8. REMOVED SPARK PLUG FROM CYLINDER 8 AND NOTICED QUITE A BIT OF OIL ON THE SPARK PLUG. WE DETERMINED THAT IT IS VERY LIKELY THAT THE NUMBER 8 CYLINDER HAS LOST COMPRESSION DUE TO EITHER BAD PISTON RINGS AND/OR DAMAGED VALVES. NOTE: PROPER DIAGNOSIS CAN ONLY BE DONE BY REMOVING THE PROPER COMPONENTS TO VISUALLY INSPECT DAMAGE.
