Hello All, I have to repair some stripped out threads on my oil drain and am trying to decide between time-sert and helicoil. I'd prefer time-sert, but I do not want to buy a whole kit with 5 inserts, four of which I'll never use (for $115.00). What have others in the same situation done? Helicoil has a spark plug thread repair insert that is very similar to the time-sert, for about $35. It looks like it would work perfectly for my application. I am kind of leaning towards taking that route. Any feedback? Thanks!
