I have an 06 LLY and for the past week or so I've noticed a Knocking sound slightly loader than the normal diesel engine rattle that seems to be coming from the oil pan area. Does anyone have an idea of what this noise could be?

Thanks for the info I'll give that a try this weekend. Anyone have any other ideas?
