I recently did my first oil change. I followed some of the Forum's instruction; which were very helpfull. When I took out the oil filter, about 6 1/2 inches of the plastic shaft remained in the engine. I don't know if it was broken before or not. I left it in there and replaced the filter and screwed the remainining shaft accordingly. It has been fine. I have since bought a new oil filter assembly and will install it soon. My question is: how hard is it to get the old remaining shaft out of the engine without doing any more damage to it.
