Directly to the right of the dipstick behind the timing belt cover is the oil pump. If the oil had leaked dry due to the filter fault, you could be looking at an engine rebuilt as the oil pump, crankshaft and con rod bearings could have been damaged by the lack of oil.
If it is only the oil pump, replacement requires the timing belt and oil sump to be removed, a 6 hour job. Not an easy job for DIY. The pump itself would cost $255.73.
Are there any abnormal knocking noises if you rev the engine abruptly?
Did the noise level change after running the engine with oil filled to correct level?
