It now has 79k miles on it. We are the only owner, and it was meticulously serviced by the Chevy Dealership. Several months ago, after a dealership oil change, we noticed the oil was low (not even reading on the dipstick). After searching found out about the issue with the defective oil ring design. I checked the PCV vacuum and that particular issue was not present. However piston #3 was burning a lot of oil, and fouling the plug.Since then we've kept a log and added oil whenever it was low. We were adding a quart of oil about ever 300 miles at one point. I had resigned myself to constantly checking the oil, and replacing fouled plugs as needed.A couple days ago, after topping off with a quart of oil, we did some interstate driving in 10F temps. On the way home the engine started running rough. My guess is that we were hit by the PCV orifice hole issue and it froze up in that cold temperature.  We limped home, and now, checking compression, I have almost 0 in cylinder #3. It will pressure up to about 60 PSI while cranking, then quickly bleed off. Piston #2 gets around 190 PSI, so I know my gauge is good.  So we either have blown rings or a damaged piston. I couldn't see anything obvious on the piston with my scope, but it's just a cheap one and not very good visual quality. I believe the frozen up PCV orifice increase pressure that caused these already bad rings to totally fail.So what is our recourse? We had already talked to the dealership about this, and they basically said we're screwed and they'd be happy to put another motor in it for $6k - $7k. Now it's toast, and needs pistons and rings replaced.  We're in Virginia. Are there any class action lawsuits on this for Virginia? Any other recourse on Chevy fixing this terribly designed engine?</blockquote>
