Cam position and Crank position sensor o-rings?
I've been through this o-ring hunt, and actually tried some different sizes. Yes -113 is not right, it will leak slightly. In metric sizes, what should work is 14mm ID X 19.5mm OD, but I couldn't find this size sold anywhere, so can't verify that it works. 14X19 is too small (bad leak), 14X20 is too big (you can pound it in but maybe damage in the process). The -113 is 19.18mm OD (slightly too small). If someone can find a source for 14mm X 19.5mm, please post it!
Also the right material is important. The first ones I used without thinking were some cheapo chinesium ones that said nitrile rubber but didn't have a high enough temp rating, when I took them out they were totally flattened.

That may or may not be right for an LS. Sites I've looked at, like Summit, say it's for a V6.
UPDATE: That part 1989866 should work for LS. Rockauto shows the size, it's almost exactly the size I was trying to find (see post 21). That part is now NOS, any you find were probably made 20 years ago or more, don't know if o-rings have a shelf life.

Just sharing in case it helps someone else—I used a nitrile rubber O-ring (20mm OD, 14mm ID, 3mm width) from Amazon. I applied a bit of petroleum jelly for lubrication, and it slipped in easily with just two fingers. No more leaks under boost
