Piston, Pin, and Connecting Rod Replacement: Inspection

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Inspect the piston, the piston pin, and the connecting rod when they are at room temperature.

Measure the diameter of the piston pin.
