I having an issue with my triton 2007. manual with 4d56u engine. I recently hear noise about knocking or ticking sound and it knocking goes fast when I rev the engine. I noticed when cold start. there is knock but goes away after a few minutes. when it reach operating temperature. I turn it off and back on and I hear the noise again and wont go away. It might be the piston expanding? or what they call piston slap?
