Time to raise ****! I said it fairly early on in this thread that that engine needed to be replaced, it is a lemon that has machining issues beyond the lifters, possibly the lifter bores or the cam. Tell the dealer that if this is what they are hearing from the Kohler rep or any more oil foaming nonsense, the Kohler rep and your dealer, Kohler Corporation, and Cub Cadet Corporation will be recieving a letter from your attorney. Just start as an empty threat, and you'll start seeing some more eyebrows raise.
I went through this with Mitsubishi Corp. many years ago. It takes some time, but if you don't get the ball rolling ASAP, you will not win.
