   Do more research! Any vapor barrier will become ineffective once you put nail holes in it. The crawl space, even well ventilated, will change the moisture content of the wood above. I guess this will depend on the climatic condition of your area, but that crawl space looks like a trouble. Did you consider a floating floor? Good luck. p.s. I would remove the old vinyl flooring. Wouldn't it be too soft as an underlayment for wood flooring?

   I am installing 2 1/4" by 3/4" T&G
   oak flooring over a 3/4" t&g plywood
   subfloor with old self adhesive vinyl squares on it. There is a well ventilated crawl space under the floor. I'm wondering if a vapor barrier is needed between a plywood subfloor and hardwood flooring?
   Thanks for any response.

   Pete, lift your tiles, and lay 30# asphaltic felt
   as an underlayment. If the tiles leave the plywood too lumpy, you'll have to clad the floor with a minimum of 1/4" lauan or better.
