Front Cylinder Head was removed due to a broken spark plug on #4. The owner tried to remove the broken plug, but broke the ez-out. Prior to this incident, the front bank had an audible knock/tick.
After disassembly, two scored cam lobes were found on #5. All of the rollers on the rocker were in perfect shape, so maybe we caught it just in time?
Service intervals were “annually” with Amsoil Signature Series 5W-20 and Amsoil filter. Since this was a 2009 Pilot with 180K, I would estimate the annual interval to be around 15K. Driving conditions were a mix of city and highway.
Note: this is a J35Z4 with VCM.
