Bent valves and a wiped CAM on a 2010 Liberty?

Any one know anything about the 2010 Jeep Liberty V-6 engines?

Trying to figure what the rest of the story is. What started out as a head gasket job (coolant leak), a week after it was done by an engine shop, ended up with 2 bent valves and wiped lobes on the Cam shaft with no other possible cause or casualty than the timing chain adjusters being weak (or not adjusted well enough/properly, when the head was pulled?) and later replaced with the 2 new valves and a used good Cam shaft.

<100,000 miles on the rig. They claim there was no piston damage.

Still has a random misfire, but no CEL light now, and a miss at idle once it warmed up (Runs fine on a cold start) and misses at 4000 rpm.

None of this makes any sense at all!!!! Pretty I am not getting the truth, or the whole story.
