My 4.3L vortec engine is apart now looking for a loud horrible constant KNOCKING. All pushrods, rockers, springs look ok. Have intake manifold off. Looking 2 C bad lifters but covers around bottom of rods. What should I look for @ lifters or anything else? R/s head is ready to come off. Where can I find torque specs 4 intake & heads. Do I need 2 adjust valves with these hydraulic lifters ?
