Many of those engines went 200k plus miles with no upper induction cleaning because they were not DI. As I tried to state I am not debating the benefit of clean intakes and valves. I'm only questioning GM and other manufacturers decision to go with this design with out a standard catch can and maintenance schedule to accompany it. Seems reasonable if it is that important. If these horror stories are true there are going to be a lot of 2nd and 3rd owners of these cars in the future who will have problems that could/should have been avoided. Of course this is all just my opinion. And I'm sorry, if a buyer is expected to run out and buy an aftermarket modification to keep his new car running within specs, I call that a design problem or flaw.

Fair enough.
