oil light comes on and the oil pressure drops

What is your question?

took to shop, replaced oil pump and then oil leaks, replaced the dipstick tube, timing chain gasket, and other gaskest, still getting leaks, dude says its the tappet pan cover gasket, replaced that, still leaking and smoking, got second opinion, its the oil pump gasket, get that replaced, then the oil pressure drops again, take it back, they claim the replaced oil pump, says the dipstick tube was leaking like a siv, so the replaced that and the timing chain gasket too. then he says, if the pressure drops again, it's your bearing!? Really? is that the case, our maintenance book doesn't say anything about a bearing regarding low oil pressure. help please? Is this guy telling us that he's done doing business with us?
