Ok, here goes. I have a 1987 300SDL and just got around to changing the oil / filter for the first time. [Yes, it was changed fairly regularly, I was told.] Anyways, the nuts on the cover for the oil filter were on incredibly tight. One of them came off with a great deal of pulling, the other one somehow sheared right off. So now the bolt that goes into the oil filter housing [the name for this is what?] is much too short to put the nut on. Do the bolts screw into the housing? Or do I get to buy and install / have a new housing installed? Where can I get the bolts, and or housing? Thanks a million!
