I have replaced two wax rings and I still get an ounce of water up from the Johnny bolt on the right side.

I replaced the flange, had to chisel out an old rotten cast iron flange, inserted a plastic flange with triple gaskets to seal. Tried a few different wax/ring combinations and at last , it still leaks a little when flushed.

All out of options, any ideas?

It could be that you have a small crack on the bottom of the toilet that's letting water seep past the wax ring, you have a leak from the tank, or the wax ring is not sealing properly. Also check to see that it is vented properly and that you don't have anything trapped in the drain

I agree it could be a crack as Merrill has suggested. But with 3 gaskets I would not expect it to seal, I have seen 2 work. What is needed is to install a compression flange 25-50$ depending on brand / quality. If this is how you repaired the first time cut the cast off a bit further down and install plastic pipe and flange at the correct level so only 1 gasket is needed. When I have needed to cut the cast further down I will usually cut about mid level in the crawl space to provide working space.

If you have a septic tank it possible it's never been cleaned and it's actually backing up to the commode and trying to make its way out the Johnny bolts
