Ok, have full Comp R roller rockers and a cc 502. Noticed the RR where taping some. Their making a clicking sound listening to them w a stethoscope through valve cover. Put a vacum tester on the intake and got 14 to 16lbs preasure. Gave the DS a half turn each and the preasure came up 1lb, but still have clicking sound. Should I try another half turn or could this clicking sound be the rr hitting the braces in the valve covers? No mods have been made to valve covers. PS has clicking too, but not as bad. One on PS side is making a grinding sound. Think it's rubbing against valve cover brace.
