Excessive (isolated) 273 Adjustable Rocker Arm Tip Wear: Diagnosis & Repair?

You can do a fine job on that rocker tip with a flat file.....or at least I could. It's not difficult. Just roll the file along the rounded face of the tip and you'll have a nice smooth surface again. As for the oiling hole, that's obviously what's wrong, since that's the only tip that's burned up. while it's true those holes don't do "much" a little is all they need and that's what those provide, just as designed.
