Mechanic replaced the seal on the timing chain cover. About 25 miles later, the "check engine" light comes on. I used a "FIXD" module to determine the cause of the "check engine" light. Code P0014, "Exhaust camshaft position timing over advanced." Mechanic said it was Okay to drive and bring it back to him. On the way, the "check engine" light started flashing, car intermittently lost power, transmission shifted gears and engine started knocking. Now the mechanic says that I need a bearing replaced on the crankshaft.
My question: Is there a cause and effect relationship between the two events?

Which seal? The one that seals the balancer doesn't require the cover to be removed so if it was that one it isn't likely that it caused the problem. If, however, it was the gasket that seals the cover to the engine, it is more possible it contributed. However, it would depend on exactly what was done. To replace that gasket you have to take quite a bit apart and it would be possible for the oil pump to get damaged and oil starvation may have damaged the bearing. BUT There is a recall on those engines as well, which actually is an issue with debris in the engine that causes them to seize up and damage bearings like yours did. As such it's a toss-up if it was anything the mechanic did or if it was the known issue with that engine.

and see if yours might be part of that recall.
