Not to my (limited?

: ) knowledge. The last engine overhauling I did, was on the FIATs we owned at that time.
I carefully removed all of the piston rings, and then cleaned the groooves with the method described? I think I mentioned it before that I then measured the piston rings with a micrometer, and they were all within the tolerances specified in the workshop manual, so I accordingly did not replace them.
Once the motor was back together and running again, it used no oil, and in my humble estimation it ran perfectly.
