Cam thrust plate oil bolt and oil diverter

You only "need" one or the other. I hope there is a plug behind the hole in the thrust plate. When I pulled my brothers 273 apart, there was only one degree wear after 300,000 miles on an old 340 double roller timing set and 4 bolts attaching the thrust plate. No 340 or HP 360 hollow bolt or drip diverter.

There is a plug with a tiny hole in it. It’s what was there from the factory so the new plug was made to match it.

You can barely see it in the center of the plug

I know both aren’t needed but more chain oiling can’t hurt is my train thought which is why I wanted to add the hollow bolt and diverter
