... The required fix should have been to fix the cause of the leak--that being the valve cover gaskets and seals.
Well, of course.
GM has never, yet, missed an opportunity to "cheap out", instead of doing the right thing. And it keeps biting them squarely on the posterior.
As much of a GM fan as I am, I have stopped feeling bad that it's costing them out the wazoo. It
needs to. Maybe if they had to pay some fines on top of all this, they'd do it right the first time.
Rant mode on...
GM doesn't care about their customers. It's all about the mighty dollar.
A most glaring example of this is the LY7 3.6 DOHC V6 engine that came in the Cadillac CTS, Buick Rendezvous, GMC Acadia, Chevy Traverse and Malibu, Pontiac G6 and Saturn Aura.
There is a known issue with the timing chains in many of these engines. There is an extended warranty repair offered for Buick, Chevy, GMC and Cadillac owners. Pontiac and Saturn owners were left to twist in the wind. So much for loyalty.
So yeah. I have no effing sympathy. (This does not even affect me. I do not have a 3.6. But still...)
/End rant.
