I have been having a on going issue.
I cant keep the lifters "adjusted". My idle is rough but on the freeway she runs well.
Today i tried to adjust the lifters again. I had tapping and slow oil pressure rise. Once oil pressure rises the tapping gets better.
While adjusting lifters I was
'bottoming" out the nut on a few cylinders. This time i was adjusting with out the motor running , last time I adjusted with the engine running.
When I fired it up it was louder. I quickly shut it down.
I noticed the rockers had a mix of slotted and round oil holes. after running a search I think thats wrong!
I have owned her around a year. This is what i think I know. Body 65 a code - C4 67 trans - Block 67 289 - Intake , accessories 65 - Heads 76 or 77. a real mutt.
Do i have to swap rocker to non rollers? Could this be most of my problem
