Bubbles can form when the oil is forced over the relief valve and any place in the system that it is forced through small orifices under high pressure. With out anti-foaming additives these bubbles can stay suspended and be sucked back through the pump causing cavitation in the pump. Again this is from my conversations with same engineer. I had this conversation with him last month after I told him about the debates about oil that we have.</p></blockquote><p></p>
