First item, to get it out of the way: what do the bolts holding the oil pan to the bottom of the block have to do with the oil drain bolt? How can a leak in one be related to the other?
Second item: Who can possibly believe that it takes 24-32 foot-pounds of torque to secure a drain bolt? My guess is that it's an aluminum pan, and this is a recipe for disaster (stripping the threads out, sooner or later).
I have done my own oil changes (steel bolt in an aluminum pan, copper washer) on 12 SAABs over 40 years. That's a lot of oil changes, and I have never, ever had a problem.
When putting the drain bolt back in, if Hyundai supplies an aluminum crush washer, throw it as far as possible and go to Auto Zone or somewhere and buy a copper one. Copper has "spring back" when the bolt is tightened, aluminum has none. This means that the washer is reusable, and it helps to maintain the tight fit.
My technique for re-installing the bolt is as follows: 1) screw the bolt back in finger tight, making sure you have that copper washer on there, 2) using a standard 3/8 drive ratchet and a socket of whatever size your bolt is, tighten the bolt just snug, and then give the handle of the ratchet one (1) nice tug. That is all it takes, and it's certainly not more than 10 foot-pounds. If you feel you cannot control this process well enough, install a Fumoto valve in place of the drain bolt (Google is your friend).
I have done oil changes on several of my kids' cars, and the guy at the dealer or Jiffy-Lube must have thought he was reinstalling the head bolt on a D9 Caterpillar. I have had to use breaker bars to get the drain bolt out. I have had several oil filters put on so tight that the housing of the filter was distorted. This should never, ever happen.
(NB: the following may be more information that you need or want)
Torquing fasteners is something that, if done repeatedly at high torque, is going to weaken not only the fastener but the threads it's engaging. Sooner or later, those threads are coming out. With some things, like cylinder heads, it's unavoidable. With things like oil pan drain bolts, it most certainly is.
Current ride: '04 SAAB 9-5 Wagon. Doing the research on a new car, YF Sonata and new Santa Fe Sport are contenders.
