Glad you caught yours and got it done in time! And you're right of course! GM should have at least acknowledged that this would be a regular maintenance item, say every 50,000 miles. That would not have obligated them to replace them free, but would have saved many a 3800 from hitting the scrapyard with an early death.
I see it as comparable to the classic Honda timing chain replacement at 50,000 miles.
Acknowledge and support...that'* all that needed to be done.
On another note, I should probably go ahead and buy my permanent replacement UIM and LIM gaskets to be prepared for my next change. Mine was done about 45,000 miles ago with standard dealership parts, not the good ones we now have at our disposal.
