Cut away the damaged portion and go all the way to the nearest joist. Now either cut it away so half of the joist upper surface lengthwise is available for the new replacement plywood subfloor piece to rest on, or attach a 2x4 along the exposed portion of the joist as a "sister" to provide an upper edge for the new piece to rest on. Use both glue and numerous screws to hold the 2x4 sister piece on if you use that method. Suggest screws no farther than 5 inches apart and long enough to penetrate by at least an inch.

Similar problem: 3/8 particle board on top of 5/8 plywood. About 60 square feet of particle board was damaged by leak under sink. Plywood in good shape.

I've stripped the bad particle board, continueing outward until I got good stuff that measured 0.375 to 0.400.

At this stage, what: Put down a new layer of particle board? Plywood? OSB? Butt the edges, or leave gaps? Right stuff to fill gaps?

Use floor leveler to fill the gaps, not foam.
Make sure whatever you use is subfloor rated.

I like to put the sheets pretty tight, get tight as possible, any gaps under an eighth . I wouldn't fill any of these small gaps unless your are putting sheet goods over the floor

I would not use OSB or particle board, personally would use plywood (unless you are putting tile over, then i'd use backerboard instead of plywood)

Thanks. Guys. Floor leveler it is.

The intent is that this is a temp repair -- 5-10 years until I can afford to put down hardwood. I put in 7/16 OSB, but the OSB is going to need a skim coat of floor leveler to bring it up to the same level as the rest of the floor (vinyl) Then trafficmaster ceramica. Good friend in the reno biz says that it's soft enough to cope with slight variances in flat, and stiff enough to not telegraph. Home depot says that any cement like product needs to be primed. So; Floor leveler today. Prime tomorrow, tile on Sunday.
