It stopped leaking for now. Using a right-angle drill with a short drill bit and a endo camera taped to the drill so I could see where I was drilling to drill some holes in the 1/4 plywood that pipe goes through then I used a Dremel tool with a right-angle adapter to widen the hole so I can see what's going on and maybe apply some kind of sealant. But then when I ran water down the drain and observed that pipe there was no leak. Maybe the material I removed released some pressure but if it leaks again maybe I can do something about it
