Well whether you know it or not, your persistence on the valve issue, ended up helping out a lot of people. More than you know.
For a long time, there were people, myself included, who insisted that there was no valve issue.
Now it is near universally accepted that there is. Only the hardest of the diehards continue to insist that there is no valve issue. And they number few on this board. They are as rare as hen's teeth in here. Indeed, it is to the point to where no one who is astute and observant in here can continue to deny that there is an issue. Your position on the matter, has contributed to what we are seeing now in here with regard to the attitude people are taking on this issue.
To the benefit of this forum membership, the valve issue is taken a lot more seriously now than it was. You had a hand in that.
To the point to where other members are being encouraged to check their geometry, and take steps to protect themselves from valve failures. To the point to where GM has come in here and made at least a token acknowledgment if nothing else. That doesn't happen if people aren't persistent in insisting that there is and was an issue.
These are things which would have been unheard of and scoffed at just a short time ago. Now everybody is listening. Especially with 2009 cars failing and guides being found out of spec in new cars with as few as 4,000 miles.
Give yourself at least some credit for what we are seeing today, in terms of the efforts that people are taking to protect themselves, whatever those efforts might be.
Just take your own vacation. Just impose a 3 month or so ban on yourself and see how you feel.
If you feel like coming back, then come back. If not, well then give it some more time.
Oh, and put some shoes on.
