Broken Rocker
Exposed needle rollers
Making metal
I have just pull a set of PCE261.1246 Speedmaster procomp ls2-3 Shaft Mount 1.7 ratio black Aluminum rocker arm set after one broke less than 2000klm with pac1208 valve springs and 130 seat pressure.
5 sets of rockers had there needle roller cages worn through the edges exposing the needle rollers and 4 had the rocker retaining circlips wearing into the rockers making metal.
This could have been messy BEWARE!!!!
