How difficult is it to replace worn camshafts on this engine? Assuming that is the problem, of course. ---

Do you think good compression would be of any value after a camshaft failure and metal debris in the engine? ---

We have a 2017 Hemi at the shop right now. 84,000 miles. Replacing the lifters requires removing the cylinder heads. Replacing the cam requires removing the oil pan, timing cover and chain. ---
