I was putting my (almost new) oil pump back on my short block after finally
getting the case halves back together when I
found that the end of one of the studs wouldn't take a nut. I took it all
apart and pulled the stud. The old stud had never seize
on it, so I applied some to the new stud (M8x1.25x42).  I expected the stud
to bottom out and leave about 17.5mm exposed, but
it kept going. Should I pull it again, clean it all up, and put it back in
with a thread locking compound? Seems like I should,
but wanted to run it by you all.

Thanks, Tom
