Hi, old thread but I have the same issue - worth a shot in the dark. Did you resolve the leaking oil pump? I removed the three screws that hold the metal lid on top of the pump and removed the lid. I found a stray plastic piece under the connector. Nothing else to do, so reassemble and tried to tighten the screws, but the leak remains. However, there was no sealant or gasket between the top lid and the bottom metal plate, which is strange, if there is supposed to be oil in the upper compartment then surely leaks must be common.
