I redid the top end 4 years ago But was under a deadline from the state of Colorado to get emissions and VIN check so I cut some corners. I know it's the rocker arms because when I did everything I put all new timing chain sprockets guides the work
So you are driving that vehicle less than 5,000 per year, or 13 miles a day.
How many times in the less than 20,000 miles did you check and adjust the valve lash?
When you “redid the top end”, what did you do? What parts, other than the timing chain kit, were replaced?
The top end typically means the head/valves, camshaft, and rocker rack.
What corners did you cut?
How many miles was on the engine when you redid the top end 4 years ago.
The rocker rack with camshaft can be swapped without removing the head.
Exactly why do you feel confident the “terrible rocker arm knock” is the rockers?
Gnarls.
