Engine Tech Discussion at Hooters Last Night
This is an exaggerated view of an engine cylinder wall after many miles.
Lets say this engine was babied all its life and was never revved above 3000RPM. Then one day the engine is revved up to 5000RPM. What result is more likely between these two possibilities:
1) As RPM increases the rod stretches and the piston ring probably shatters as it collides with the lip.
2) The piston ring does not shatter because there will probably be enough up and down wear for the rings to move in the piston ring grooves in the piston.
Your thoughts?

Very interesting over the years we have seen engines with broken rings mostly after a rebuild with new bearings and new rings and the crank reground the piston would be a lttle higher in the bore at TDC and the result is the ring making contact with the ridge or we have seen new pistons intalled and with the tight ring lands and new pistons I have seen ring lands and rings broke.
I would think that on a high milage engine as the rod and main bearings wear and the rings and ring lands wear there is a little room there.
Just my .02 cents

Ok...so you're sitting in Hooters....and THIS is the conversation topic? I'd love to know how that one started.....
Was there an "over the hill" looking Hooter's girl or what? Did that make you start thinking about wear patterns and what would happen if she was "handled aggresssively"???

Something like that...There are no over the hill girls at this Hooters. The girls are all brand new and shiny, like they are fresh out of the packaging.
