Make sure you have clean oil for the lifters and a clean fuel filter so the injectors get enough fuel.When the ecu sees less fuel it increases the injector pulse to compensate and goes noisy as they work harder.
The other very common offender is loose exhaust manifold bolts or leaky exhaust gaskets

This may be causing your air fuel ratios to go very lean and the ecu is pumping the injectors hard to keep the engine safer.
