Valve train noise

Billbo said
The rockers are not bushed that is correct. After honing there is very minimal play on the shaft. I measured about 0.002 to 0.003 thou clearance no less. I a way its a good thing oil flow. It made no difference before and after anyway. But I'm glad I pulled it apart and cleaned the surfaces. They slide like they are on ball bearings.

Those are some oldies.
Havent seen those in years, last time was in a book by Bob Mullen.
I just pre load them till they're each quiet with adjustable rockers...usually 30 thousands does it. I assume the shaft came with the Rockers so the oiling holes are lined up right.. but idk it looks like the holes are close and I want them pointing toward the spring and at the bottom.
The noise...Could just be the little rollers are loose, in addition to the rocker bores & sideplay....you're maybe hearing a lot of clearances close up every time the rocker opens the valve is all.
