Can a bad FICM cause engine damage?

I bought a 6.0L ford CHEAP with a bad engine for a project. I am a Cummins guy turning to the dark side so I've been surfing around this forum for several weeks now gathering information on the 6.0L. Most everyone here seems very knowledgeable and friendly so I thought I would pose this question.

This 6.0L has two bad pistons. #4 piston just looks like it had been over fueled and has melted the piston. #1 however dropped a valve and has some pretty major carnage. I can't quite tell for sure but I think this piston was over fueled also and that may have contributed to the valve dropping. So my thought was these failures must be related as it would be an amazing coincidence that these two cylinders failed at the same time from two separate causes. Is it possible a bad FICM would cause this kind of damage if run to long? This pickup was BONE STOCK with 170,000 miles. Didn't even have a programmer. Was used to pull heavy horse trailers. Pretty sure he was towing when the those cylinders gave up.

Any thoughts on this or suggestions on any thing else I might have missed?
Thanks

I've never heard of a bad FICM causing anything close to this. I've seen them take out injectors or just quit completely and not allow the truck to start

I don't think a bad ficm was the direct cause... sounds like a sticky injector to me. however... A ficm can contribute to a lot of problems leading to injector failture leading to major engine damage... low volts on a ficm kills injector, so depending on how the injector handled dieing it could of overfueled, burning out a piston to.
