      I have heard of three C8 corvette in the St.Louis area that have broken valve springs. One destroyed the engine ,the other two just needed new valve springs .

        Sad but one of our MECF members picked up their new C8 at the Museum today, and seven miles later it had broken valve springs and sits at Campbell Chev in Bowling Green. They are close friends of ours and we’re heading home to Oregon. When they met with the Service Manager a couple of hours later he noted that this was their 5th LT2with broken valve springs, that their dealership had the dubious distinction of having more individually than every other dealership, and pointing to one parked in another bay, said it’s valve springs had destroyed the motor and they were awaiting a brand new replacement LT2.

        Our friends remain in a fairly positive mood, noting that they loved its workmanship, greatly enjoyed their first seven miles, and we looking forward to driving it home on Tuesday. Do they get the “most positive attitude in spite of massive xxxx award!”

            WOW - I don't even know what to say, that makes me feel sick. Seven miles! At least after it's fixed they shouldn't have to worry about that issue any longer.
            That makes me want to start tearing my C8 apart and putting roller rockers and high performance springs in. Shouldn't they have scrapped all the springs from that manufacturer?
            Why are they still showing up ?

              I would have done this already! You know GM will not be stepping up--they never have and never will it is all about $$$$'s.

                If they just picked their car up yesterday, it seems likely to me that this car was built outside of the date range GM first specified. Makes it seem this is potentially a much more widespread issue than announced.

                  I feel sorry for those people, but they should never had been put in that predicament. I hope GM is paying for the hotel, meals etc. Don't think trip insurance was an option on the C8. Glad they are looking at the bright side. I know I would have gone berserk.

                    It was built within the range, on Sept. 9th. Business interests precluded their getting it earlier. However as we know, we have seen a member’s one build on Sept. 18th.

                    Still so sad for them to have their dream (their first Corvette) end so poorly.

                      Is there any data on highest mileage car that’s had an issue? Ours was built in this “window” and we’re at 320 miles. So far so good.

                        The highest I have seen that we know was valve spring caused was less mileage than yours — to my knowledge. We have seen a couple of motors totally go south at higher mileage the causes of them has not yet been shared. At the same time in comparison to when the C7 first came, out the number of motors that have head failures for the LT2 is probably on the order of one LT2 compared to 10 for the C7 LT1.

                        We do not yet know the magnitude of the LT2 valve spring problem. For those new to this discussion, the valve spring problem is a GM problem covering nine different motors .

                              I have 2 vehicles within the time frame. My C8 has 630 mi (so far knock on wood) and my 2020 Silverado 5.3L L84 has 490. Driving isn't as much fun as it use to be. Maybe if I make it to a couple of thousand miles, Ill have more confidence. My previous experience with broken valve springs occurred at high RPM's.

                                This is a sad times for C8 owners whose C8’s could be effected. It is also sad times for the Corvette team for they created a phenomenal car for us and their suppliers are kicking them in the - - - - repeatedly by sub-standard products resulting in recalls, But even before then it was the strike (zero fault of the Corvette team), then it was the Covid shutdown (ditto), and now four recalls due to suppliers falling down. Oh yes, one more nightmare for them, that some amount of suppliers can not keep up with production causing even more severe problems for the Corvette team — and of course for us customers as we are downstream recipients.

                                I truly feel sorry for the Corvette team because of all these things. Just as I do for many of us C8 customers’ many issues starting with not getting their cars in a timely manner due to all the above and now the recalls.

                                One big SUPER UGLY YUK!
