Means something is drawing power..

Check engine mounts,, the mechanic may be right about the cylinder..

this will not show in any diagnostic,, but has to be inspected individually..

for a crack,, just the engine block needs to change..

DO NOT P[OST A NEW PROBLEM, STICK WITH THE ORIGINAL THREAD.
