4G93p engine knocking sound

[pje]

I need some advise from any 4g93p sifu..

My engine produce knocking sound 'ketak,ketak,ketak...'non stop. Before this, the sound just a while only, a few second after engine started. Are they tappet or what?

For your info, i used Eneos semi syinthetic engine oil.
