I have full time oiling for the last 25% of that rockers life. Been 8-9 years since I went through and I was not very nice to it early on. It owed me nothing.
Damn. Yeah, they reached the end of their service life.
I forget what Chrysler said about unbushed rockers and lift or spring load but they had a standard or whatever when you should switch to a bushed rocker.
I can’t remember if it was load, rpm or lift. At this point I just use bushed lifters and not mess around.
MBTW, how did you get you oil full time to the rockers?
