....well by puke I mean it barfed up half of the 6L of new nice expensive oil I gave it. It's a 81 240D and I just did an oil change. Something seemed a little funny when I was tightening the nut back on to hold the top on the filter housing. One stud was showing more thread than the other. I thought it was odd that I hadn't noticed it before. I gave her a start anyway, after about 20 seconds my oil pressure gauge would not quite make it to 3 bar as it usually does, I shut it off only to find the nut and stud totally loose and oil all over the driveway.

The stud has come totally out of the housing. Does anyone know of how to fix this problem?
