The engine make tapping noise at idle and stops when step on the gas pedal ?

Lubrication to valve train is probably low. Engine is burning oil. Power loss is obvious and the intake air duct has oil moisture when checked. This is a sign of plugged PCV valve, blow-by gas with oil is getting into intake manifold through crankcase ventilation hose. Replace PCV valve and crankshaft seals if there's a leak coming from the seals.
