Piston ring groove questions
What is the most common (or most likely) reason piston ring grooves become
excessively wide? Does piston slap contribute to widening of the piston ring grooves? -- TeGGeR® |

For sure excessive piston rock in the bore can cause accelerated ring groove
wear, how worn is worn and how many miles on the engine, maintenance and driving conditions all are in the mix here. Remember for the most part piston slap is gone when the engine warms up and it is not all the cylinders usually, so if all the ring grooves show excessive clearance I don't think piston slap would cause this.

Besides the obvious cause by high mileage, running at light load and
elevated rpm can reduce gas loading on the rings to the point where they flutter. This tends to beat both sides of the groove.

City driving in too low of a gear, or steady 85mph at 4,000 rpm? -- TeGGeR® |
