Services Performed
- REPLACE EXHAUST VALVE SPRING #8.
- WE SCANNED FOR CODES: P0300 – random misfire detected P0308 – misfire detected cyl 8. WE CHECKED SPARK, FUEL AND COMPRESSION. WE CAN HEAR POPPING AND CLATTERING IN THE INTAKE. WE REMOVED VALVE COVER AND COULD SEE A BROKEN EXHAUST VALVE SPRING ON CYL 8. THIS IS CAUSING THE VALVE TO NOT CLOSE PROPERLY AND IS ALSO AFFECTING THE OTHER VALVES. THIS WILL CAUSE A MISFIRE. RECOMMEND START WITH REPLACING THIS SPRING AND WE WILL RECHECK VALVE FOR ANY DAMAGE. AFTER REPAIR WE FOUND THE ENGINE TO RUN 90% BETTER. BUT WE CAN FEEL A SLIGHT MISFIRE AT AN IDLE. WE PULLED SPARK PLUGS AND FOUND #3 AND #5 PLUGS FOULED. CUSTOMER STATED THAT HE WOULD LIKE TO PICK UP TRUCK AT THIS POINT AND WILL TRY TO DO HIS OWN DIAGNOSIS AND WILL RETURN THE TRUCK IF NECESSARY.
