What would explain the squealing sound from the front of the engine? Can an opti have internal damage and still let it start and run like crap?

The rotor's in the Optisparks have been known to come apart at high RPM.

Sometimes there is still enought of the rotor left on the stub shaft that the engine will still run. Then the parts of the rotor that came apart can get hung up in there. Those parts of the rotor could be making the noise.

Of course rod brgs squeal before they start knocking as well.

Without actually hearing it, we are all just speculating at this point.
