Filter housing leak

[seattle240D]

Hello diesel faithful.. I come again with a car on the side on the road.. The other day I did an oil change on my 1981 240d and overtightened the bolt on the top of the filter housing causing the stud to strip out of the housing. when I turned the car on the sucker didn't hold the pressure and I shot more than a few quarts of fresh 15w-40 all over the driveway. Went to my parts guy and he gave me a new stud that I put into the housing. It's longer and seems to grip nicely in the housing. Drove for a couple days (up stevens pass, no easy feat) no problems.

I am on my way to Vancouver, BC last night, just filled up with gas and no problems on the road. Pulled back out onto the highway and revved up a hill in third, changing gears at the top into fourth and boom white smoke gauges drop obviously the cap loosened up and blew out the oil. Pull over pop the hood and yeah, oil everywhere.

Here's my question: the stud seems to be secure in the filter housing. It appears as though the top bolt is stripped. When i go to tighten the bolt it becomes tight but then slips back to being loose. I can finger tighten it and it seems tight but one more light rotation and its loose again. Anyone know where to get the top bolts for w123 filter covers? Any other issues I might be failing to see? It was all going so well!!

Stuck in bellingham for now…
