Hi wkhairulnizam@yahoo.com,

Welcome.

The wet spark plug doesn't necessarily mean you need to rebuild the top end at all. It is probably just due to no spark on that cylinder, because of faulty spark plug leads or similar.

With the knocking, worst case is your timing chain failed, or the engine is pinging, but it is probably loose tappets. Noisy tappets are not the end of the World.
