Yes, it does happen from time to time.. and a bit of thread-lock loctite etc should keep the threads locked in..
Its just that the thread hits the end of the capped nut and locks up... and the stud is unscrewed..
It doesn't take much to strip small threads like that Wayne.. it pays to use a small spanner and just tighten the nuts and check every now & then, its best to park Your Beetle over a piece of white cardboard or any clean board so You can see when its dripping oil... most do anyway, but if You can stop a leak its a Bonus...
VW changed the sump plate to stop people changing the oil without cleaning the strainer... well, I had VWs in the 60s & 70s and never ever took the plate off!! I just did what everyone else did.. took the drain plug out..
Another Invention - the Magnetic Drain plug - this should attract any pieces of metal floating in the oil... if the particle is too large to get into the strainer- it won't be sucked up with the oil pump.. anyway...
I have added a CB Performance Maxi Sump which has a finer gauze filter- to My Beetle's engine. My sump plug is a temperature sender... another invention..
will these inventions never stop!!
