My ride is down...bent valve ??
Car went into limp mode on the way home, thew stabilitrac message and transmission was acting like Tourque Conv was screwed up....yeah I had the ol’ TC replacement done about 2 months and 3k ago. Dealer called me today to let me know it is more involved , possible broken valve....ugh.
I hate giving her up to a dealer, regardless of how good they are (Stingray in PC Fl.)
Was driving along....energetically....and lost throttle response, for a moment thought I could punch thru and limp to dealer 12miles away...the way the rear ended felt was as if I was rolling over bumps in middle of the road, classic TC symptoms, but engine would barely hold an idle and was running rich as hell (lots of white smoke , strong oder of gas) so ...we shall see....anyone have a similar experience ??
Update 3/1...dealer determined it was a trashed lifter...replacing all of the lifters and cam..get the car back next week ...ugh

Strong odor of gas suggests rich mixture or fuel leak.
Best of luck to you.
Still under powertrain warranty?

Bent or Broken Valve..You could be getting a new engine.You kept driving it.If bent i would demand a new ASSEMBLED Head.Banging out a bent valve will damage the valve guide.That is a pressed in insert the valve rides in.A valve guide has to be perfectly centered with the valve seat.New Head assembled factory would be my minimum.Could be jumping ahead here but just throwing some info. in.
If it stayed in the head you might luck out. If the valve broke and they wanna fix it?
I would be inspecting that cylinder bore and piston before the head goes back on..Take pictures we wanna see..Good luck..Keep us informed..Thanks

Everything I've read about that dealer, you're in good hands. It'll turn out ok. Glad the car didn't do worse (not sure what that would be ) Good luck.

To bad you can't check on the process.I would demand a photo of that troubled cylinder when the valve cover comes immediately off.I would want to see if the valve keepers and spring retainer are still intact.If are that will save searching for shards of metal in the oil.Oil goes to soft bearings.Not good.A good photo would be when rocker arms are removed.How low the bent valve sits oppose to the other valve.That would tell me how far or hard of a hit the piston made contact with it.
That would be me.Hopefully the valve ain't bent.
Guess if confident with dealer that is huge.If not fixed right it won't run right and warranty kicks in again.Sucks for the delay

Thanks ....that is what they suspect (Valve) hope it is less problematic
Smart moveValves just don't bend.Unless they have help.Read here about broken valve springs.Springs will break if defective or over revved.When they break all kinds of destruction can and eventually will,if driven be very catastrophic.
