I can't find any valve adjust intervals in my service manual I down loaded for my truck. I found what to adjust them to but not what milage to adjust them at. I probably over looked it but does anyone know what the intervals are?
Okay I talked to the dealership, 3 actually, and according to them you do not adjust the valves. They are hydraulic self adjusting according to one of the technicians at Bill Heard Cheverolet. waytogo
