It will not close quickly or completely, on intake it will cause loss of compression and backfiring, on exhaust also loss of compression.
There may also be some noise from piston hitting valve, and possible damage.

the valve bent because the piston hit it, due to a weak valve spring or over revving the engine

What is Valve pocketing?

Will a weak valve spring perform more poorly at idle speed?
A valve spring's job is to close a valve opened by a mechanical or pneumatic opening mechanism. The weaker the spring, the slower it will close the valve. This usually manifests itself by the valve 'floating' at higher RPM's. As a spring weakens, the RPM at which the valve 'floats' will decrease. In general, the valve will still operate at lower RPM's, but not at higher RPM's. To achieve higher RPM's, engines built for performance usually use stronger springs to return the valve as quickly as possible, to accommodate the reduced time available to close the valve. The tradeoff is that the valve is slammed against the seat harder soon wearing both out.

How do you remove valve springs?

What is the purpose of a valve spring in a petrol engine?

What is the effect of weak governments?

What is the purpose of a valve spring in an engine?
The purpose of the valve spring is to maintain contact between the components in the valve train, so the valve motion will follow the cam profile.
How do you know if your valve spring is brocken?
Your engine will probably missfire and you will not have compression in the cylinder that has the broken valve spring because your valve will stay open.
What is the right spring material quick release valve for steam application?
Spring loaded safety valve.
