knocking noise from engine, especially after the engine gets warm.

The 2.5 L engine has hydraulic tappets. There is no adjustment . You may have a defective tappet or are hearing the knocking noise from another source, possibly carbon buildup on pistons, piston slap, or lower end bearings.
I also have this same issue. What did you find out? I would sure like to know as I am leaning towards listers or valves Thanks
