I installed a Koehler 1.6 gpf toilet. There is a slow leak from the tank to the bowl, just enough so that the tank refills every 15 min or so. I have replaced the ball valve; still leaks. I removed the tank and gooped up the washer and the bushings with silicone grease; still leaks. I know the leak is going into the bowl since I put some food coloring in the tank and see it seeping into the bowl. Any suggestions?

Several things come to mind which you may already have tried. Check that the float level is adjusted so that the water level is below the overflow tube. Open the flapper valve and run your finger along the sealing surfaces of both the flap and the seat to make sure there is no lump of crud or a gouge. It's possible there is a crack or hole in the overflow tube or base.
It may be siphoning... water level a tad high...

Yep, it was siphoning. Thanks so much!
No problem...
Tube set too deep or water level too high???

Same difference.
Sometimes the fill valve on new toilets is really stiff, and takes a good amount of force to be really closed. Try bending the float arm, and then adjust the level by using the screw on the valve actuating arm. Your goal is to get the tank to fill as high on the float body as possible. The deeper that float is sitting in the water, the harder it is pushing up on the arm.
Sometimes pulling the bowl-top-up tube out of the overflow channel and directing it into the tank itself will help fill the tank just a bit higher on the float, as it tends to close after the main fill line. You don't usually need the top-up function anyway; most of that water just goes down the drain for no purpose.

Siphoning. Check that the fill tube that runs from the inlet valve into the overflow tube terminates ABOVE the waterline in the tank.
That did it! It was siphoning, now that I think about it, of course! Thanks so much!
