I am having a leak from this stud from the bottom of my 2.7 engine. Correct me if I am wrong, but I think it's a bad nut because I have put a number of washers behind the nut and tried to tighten down and it wouldn't take much of any tightening.
So anyways its leaking from this area that I have never been able to tighten and so I have lived with the leak.

Isn't that a through case bolt ? Is there not supposed to be a green o ring under that washer ?

The stud just pokes through on the one side. All I know is that the nyloc nut has a washer behind it.

Case perimeter studs.

And the Mg threads have pulled. One of the many irritant points with the engines, but thankfully not a failure point like head studs.
