Conrod oil holes

What is the general consensus of opinion on the conrod oil holes? some say cover them up with the undrilled shell to avoid over oiling the cylinder wall. Seeing as there s no groove in the shell it's only going to get a quick squirt when the crank big end journal holes line up with it. Or am I missing something here?

The previous discussion on this, way back into history, is that the oil squirt holes were an attempt to fix a problem that didn't quite exist - as they thought.
Fixing the PISTON PROBLEM fixed it, and the oil squirt holes were redundant. And bleeding pressure off the big ends.
Thats the history of it, maybe someone has some more specifics on the hardware side of it.
I wouldn't know a duff piston/gudgeon pin if I tripped over it....

My opinion is they don't hurt anything so I leave them operational on a streetbike.
Racebikes get Carrillo's without the holes. Jim

If ya moved the hole to either side of rim of the big end like my lawn mower it'd throw significant oil under the piston for full down stroke. The hole is identical to the wart like remains of a useless toe in horses. Early big twin piston seizures was 1st thot to be lack of pin lube so hole was tired but didn't solve seizes then a bad batch of pistons discovered but the order for rods with holes was never changed. Best to just cover em so quicker oil pressure on starts but fun to pump oil thru them with piston mounted to see what happens an instant at about 11 & 2 o'clock points. If they mattered it would not be about standard race practice to block em.
