Engine Destroyed
#41
Bro I hate to see this type of ****, but coming from a guy who’s had the absolute worst service from a local shop I’m glad to here this place is going above and beyond and doing the right thing in your case! I’m sure they’ve more than likely earned a customer for life by doing this. In my case the list of all the bullshit I’ve been through with my shop is too long to even get into, last Friday was the absolute last straw and I’m pulling the car out of there incomplete and moving it to a new location. I’m not even arguing the final invoice that’s is higher than the original quote that I paid half up front and I had the engine builder do 100% of the engine assembly to include heads, cam, clutch and harmonic balancer, all that was included in the original quote I paid half upfront for. So way less work yet more money, whatever though don’t care at this point. I’m just trying to get them to cover the damage they did to the exterior of the car while they had it in their possession and I’m not sure they plan on doing that. They took possession of the car 96 hours after a two stage paint correction and 7 year ceramic coating was done, exterior was as close to flawless you can get a 12 year old black ZO6. Luckily I do have tons of date/time location stamped pictures from all angles of how they received the car and what it looks like now, **** I even brought my car cover up there and personally covered it when I realized how long the build was going to take, they removed the cover shortly after and it never went back on. I doubt they will do the right thing so hearing about a shop taking ownership and doing what’s right gives me some hope that not every out there does business like what I’ve seen. Sorry this happened man! But I’m glad to hear it’s being handled with some honor and integrity.🇺🇸

Sorry to hear that man. I try to give people the benefit of the doubt and believe there’s still some good souls out there. It’s been tough. I’ve had a couple instances w this shop and was sick when my Z went down last wknd. I just try to live right and know all this material stuff is temporary anyway. Not tryin to go all religious and stuff, just had a few drinks...lol. Everything will work out like it should bro. Keep doing right and when all else fails, run that Z thru 6 gears and smile!

I also think it’s a good idea not to openly smash a shop or company unless it’s literally your very last option. There’s not much to gain from it and in some instances one persons experience with a shop or vendor could be completely different, some people have different expatations on services, timelines and punctuation and sometimes good companies/manufacturers have a slip up in quality control, so I respect your instinct to hold back on blasting people publicly. I don’t plan on doing that to this shop even though I probably have every right to, when my rebuild thread goes up and if I get any of the questions you got I believe I’ll tell anyone that must know a name and location to PM if they must know that badly. I’m active duty military so I heard then General Mattis drop this quote before most of the population heard it and it sunk in instantly and I live my life by it......every damn day. I just don’t see how you benefit from not keeping your cool and staying professional, as shitty as that is, it’s more than likely the best position to take when **** like this happens. Sorry to jump in your post and write a damn novel, but I can personally relate and the corvette forum is the only place you can safely bitch and complain about all your corvette problems and fine some genuine sympathy lol.

Solid stainless intake valve is V-E-R-Y heavy compared to its Ti counterpart. Could there have been severe valve float causing the piston head to smack the valve??

Hard to say. At this point I just want my ride back. I have a clean slate, but I don’t want to go the crate engine route and have to address the same issues down the road.

My thoughts exactly.. You need to have a good reason (and being cheap shouldn't be one of them) to move away from the stock Ti intakes.

The fracture face indicates the most likely cause of failure is bending fatigue or tensile shock load. The beach marks appear to to only travel in one direction. Bending fatigue can almost certainly be ruled out because the valve should be turning as it's in operation, and the fracture face does not indicate this. During disassembly valve lash should have been checked to rule out it being too loose.

Even if the shop is only doing this cause they might feel it was caused by them who cares? My hats off to them for stepping up even if they dont want to admit it. It sucks that the part failed but yours shop stepped up to help you out when then didn't have to. I think that speaks mountains. If this was my shop I was going to, I would totally continue using them.

A solid look at that valve under good lighting and magnification would reveal a metal defect. There should be no "might be caused by" . And to take that a step further we should all expect our shops and our manufacturers to stand by the products and services they are producing.
The metal doesn't lie.

Is there any evidence of piston to valve contact on the cylinders that aren't destroyed? It may be subtle. What are the pistons made out of? Were the springs and valves matched to the cam profile by the valve manufacturer or was it a hodge podge mix recommended by the tuner?

Need help with a sudden ticking noise 2011 LS7
Very aware of all the questions about the value guide issue with the LS7.
I have 23,000 trouble free miles on a stock 2011 LS7. Very little valve noise at about 1,700 rpm.
Started the car today and notice a loud ticking noise and when i started to accelerate, there was a slight surge. Turned the car around and right back into garage. Does this seem like the dreaded valy guide issue? Would driving it cause a rod through the block?

Could be a wiped lifter, bad cam, spun bearing or many other things. Typically ticking noise isn't a "valve" drop issue, because it just happens and boom.
