hi there just changed my oil this morning on my 1300, 71 bug and when i was doing up the six nuts that secure the oil strainer plate, one of the nuts was turning without tightening. great i thought, but it gets worse!!! the thread on the nut is fine and the thread on the stud is good but the thread in the botom of the engine case has been stripped!!!!!! ohhh fuk
so what do you recon is the best was to fix the thread????
i thought i could heli-coil it but im not sure if they will seal the oil???
or could i go to an M8 thread???
any help or advice would be greatly appriciated
