The threaded fitting that the oil filter screws on to on my 2001 Zx2 2.0L Zetec engine came loose. It started to unscrew from the engine block when I was taking the oil filter off at the last oil change. It did not come completely out and after I got the oil filter off I screwed back into the block as tight as I could by hand. Does it have an internal hex or something so that it can be properly tightened into the block. If so does anyone know the wrench size? Its hard to see from under the car.
Thanks
