[R129 SL] Oil leak follow-up

I wrote to this list last week about an oil leak on our SL500 for a couple of months. Not terrible, but
definitley not good since I needed to have newspaper under the car. This is a 1998 SL500, 119.982 engine.

Fortunately this problem looks easy to fix. The oil pan bolts were all loose, every single one of them, especially the ones at the rear of the pan, which I got 1/8-1/4
turn on, and I haven't even torqued them to spec yet (9nm).

Anyways, next weekend I'll be doing an oil change along with the 60K service. Sort of a good time to replace the pan gasket. Pretty simple, it looks, since there are no cross-members or other body or suspension parts in the way of lowering the pan. I'll be checking things over this week and am thinking that when I drain the oil, if things are not leaking when I drain the old oil, I may just take the allen-head bolts out one-by-one and put a small drop of blue loctite on them. All of them were loose on the car today, so by quite a bit. Perhaps the loctite will help keep them from loosening again like they have in 8 years, 60K miles.

Curios as to the R129 list recommendation. Would you recommend I replace the gasket next weekend, which is an ideal time given I'm draining the used oil for it's change?
