Hello and welcome to JustAnswer!
There are many things that will cause a noise inside the engine. A broken valvespring or loose rocker arm will cause a knock type noise from the top en but should also come with an engine miss.
if the engine runs ok it's more likely to be a piston, wristpin, or rod bearing issue. You can try killing each cylinder one at a time, if the noise lessens then you have a piston, rod bearing or wristpin issue.
The problem appears to have started after the engine was overheated?

Yes the noise started after it got hot when you rev the motor the noise fades away but when idle it's a taping sound

Have you killed cylinders one at a time to see if the noise lessens?
