Thanks for the information man. I need to do the valve cover because I have had the low power/ half lit transmission light come on a couple times over the past year. Sounds like that's from the valve cover leaking causing low boost. And no I don't believe a word the salesman says. I just got an overall feeling that the people up there salesmen/ foreman/ techs are all in it to not do any warranty work because it doesn't pay them as much. Anyway they can do/explain to clients to steer them in another direction to avoid the trouble they will do it. This may not be true, it's the just the feeling I got from the little bit of bs here and there.

If you have a hand held vacuum pump you can easily diagnose the problem yourself, take them out of the loop.

Yes we do prefer customer pay stuff over warranty because it pays more, I don't know that dealer operates, but if kne of our guys sells a job as customer pay, and it doesn't fix it, they don't get the labor time for that.

Installing a waste gate seperate from a turbo (which I would never do) is time consuming and tedious. You could always tell the shop you want someone else working on it. The guy working on it may not know how to properly diagnose that issue. That doesn't means he's trying to screw you over, he may just be wrong.

Either way, 45 mins of your time and 30 bucks at autozone on a vacuum pump could save you a good chunk of change. Pm if you want help testing the waste gates.
