Hi:
Does this sound more like a bearing knock or a ping while under a load? Does it happen all of the time or only under certain conditions?

The only thing I can say with a knock is that it is usually a bearing problem (rod, main, cam...). Make sure the oil is full and that you are using the proper weight.
