Only the Oil Control Ring groove has oil relief holes that allow oil to return to the crankcase -- the first two rings do not

It shouldnt return to the crankcase if the rings are worn. The oil should burn in tyhe combustion chamber and be released through the tailpipe as blue smoke. Oil is drawn up the cylinder wall from the compression and then the wall is wiped clean on the exhaust stroke. This oil lubricates the piston walls so not to prematurely wear out the rings around the piston.This is a very minimal amount of oil and does not burn up in the exhaust.
good luck........
