Subfloor over pine

So old pine woodfloors with linoleum over that. I scraped the linoleum up (prob shouldn't as more than likely black is asbestos). No now I'm going to lay down tar paper the some osb then hardwood. The floor is pretty stroaght right now prob within a half inch.
Will that be good enough for level?
Should I sand the osb once on to level it?
Should anything go under tar paper to seal it, kind of smells like glue a bit now
Thanks!

Anyone here?should this be in a different category? Trying to do this soon.
So should this be all set? Do I leave a bit of a gap with subfloor and wall?

Bottom line, the glue needs to go. Your adding osb to it will only exacerbate the floor's unevenness. You would not lay tar paper between the layers. Save that for under your hardwood flooring. Yes, leave a gap at the edges since you have not removed the baseboard.

Thanks for the help
Baseboard will be coming out because it is too low. That glue really isn't going anywhere unless I sand it flat and that isn't happening because of the abspestos. It really isn't that much of an unevenness now 1/8 to 1/4 inch over the room. If I don't mind of unevenness should nothing go in between the old floor and the new osb?

Right, you want the two layers to breathe. Also, don't fasten your subflooring to the joists. You want to intentionally miss the joists to create a "slip" effect between the layers. Place your builder's felt between the subfloor and the hardwood.

Really ? My plan was to hit all the joists. You saying miss the joists 100% or just don't aim for them.

Miss as you can. If you tried to hit them, you would have a rate of error. That same rate of error will exist when you try to miss them, so try to keep in the field.
