Far right

 

Anyone have input on cause, effect, repair? Is my cam done? Just replace that part? Is it called a roller rocker?

If you want to purchase new, here it is from Acura:
14620-P8A-A01 Genuine Acura Intake Rocker Arm Assembly (acurapartswarehouse.com)

$6 cheaper new from Honda:
1998-2008 Honda Arm Assembly, In Rocker 14620-P8A-A01 | Majestic Honda Automotive Parts

Even cheaper used on ebay:
HONDA OEM ROCKER ARM SHAFT INTAKE & ROCKER ARMS #14631-P8A-A00 | eBay

 

Appreciate those links, you think that would've been a lubrication issue? Engine has 240k on it at this point. Would the cam be smoked? Seems prudent to me to design the roller with a lower modulus as to preferably wear over a cam.

 

try reposting this on the main forum, I didn’t even know this existed so the traffic may get you some more input.
