Over a period of time I've changed all my engines to 1/4" BSW studs and Nylocs. I wouldn't change back. Once the stud is in place and tightened, that's it. No risk of damage to the crankcase threads by the removal/re-fitting of sump bolts and the nature of the stud means that the possibility of oil leaking down the thread as can happen with bolts is removed. I've never Loctited the studs in although I see no reason not to. Just made sure the crankcase threads are clean and oil free by thorough use of brake cleaner and then fitting the studs and tightening them in by carefull use of a roller stud extractor/fitter. Although it will upset the purists, 1/4" UNC studs and nuts work equally as well given the similarity of the two threads.
