I agree with Sixto, especially if the chain rails and tensioner are OK.

Can you post a photo of the missing teeth? I'm not seeing that in your previous photo.

The chain doesn't automatically require replacement, but it would be a good ideal to mark a link on the chain, and turn the engine by hand so you can inspect the entire length of the chain. If timing marks are aligned, AND stretch is within factory specs, AND there is no visible sign of damage to the chain... I'd leave it alone.
You really should drop the oil pan and inspect for debris in the sump. This may also help solve the mystery as to what caused the valve cover to pop in the first place. It may be a miserable job; I'm not sure what's involved.
Replacing the valve cover won't be cheap either, new is ~$250 from discount dealers, a used cover may be difficult to locate. If you don't identify the root cause, you'll be really unhappy if you install a new valve cover and have the replacement cover suddenly get extra ventilation like the first.
