POLL: Valve Problems
 

Wish I could or knew how to make a poll. Probably need to pay...


Either way... I say we should create 1 damn thread about the discussion of the exhaust valve problem in the LS7 and make it a sticky. I don't know about anyone else but in my opinion there are way too many concurrent never ending threads about this issue and its mucking up this forum to be honest.


Anyone else agree?

I tried that myself and it went as far as 2 weeks at best. Just too many variables to capture every LS7. On a positive note, POLLS are free. When you make a thread, there should be an aread to check that says "POLL". If you leave it unchecked, your thread will be posted as a simple thread, without a set of poll questions.

As a sidenote for the forum, the moderators here don't listen to feedback when we ask for a thread to be stickied. Good luck with getting anything stickied on this forum lol

Thanks, I found the option. I also appreciate the feedback. You would think there are a lot of variables but mostly all I see is 37 pages of insults and a few solutions peppered in.

Shame. :(

The discussion of this matter will continue for as long as it continues to happen.

There is no abating the discussion of it.

As it increases in frequency, or potential instances of it increase in frequency, so will the discussion of it .

Another potential one just about an hour ago.

This new one to go along with the one from Bill Dearborn, 1 Bad Burb, Cantevendrive78, all within about a 7-10 day period.

All confirmed, feared or believed to be the same issue. Stock exhaust valve failure.

But do know, that if it were not happening, then there would likely be no discussion of it.

One thread though?????, and you would wind up with perhaps thousands of posts in it, making it impossible to navigate.

Not sure what you are looking for my friend.

There are two basic ways of handling this problem.

1. Stock valves, bronze guides.

2. Stainless steel valves, bronze guides.

Pick an option based on what you have seen in terms of the reports in here, what cylinder head professionals and shops that you trust after you have had a chance to ask yourself just why you trust them, have to say, and go with the option you are comfortable with.

No need for a new poll.

Are you seriously turning even this thread into another valve discussion?

Thank you for proving my point. Either that or you missed my point. :rofl:

Also quite honestly Quick. I see the same 5-10 people posting about it. Sure new threads come up and they should be consolidated. Lots of other reasons to own the Z06 and reading threads on this forum was my point.

Consolidation would be good. Too much clutter.

Too much BS quite honestly. Look at that other valve thread. A pissing match for the last 7 pages.

Quick, I like you bro, but how can you say that is productive? Also its what every single thread about this issue turns into with the same participants.


The next drama the next drama thread:

Both will turn into 10+ pages of pissing match over the same crap with no new data. That is my point Quick.

it's just now starting to get rolling. the failure rates are gonna go up. I agree with you. but when ppl lose a 15k engine some will be pissed and make their own thread I would

1. Agree on the consolidation, OP. Or a sub-forum.

2. Why must a holed block result in a $15K engine? Seriously, wouldn't a bare block and a rebuild with salvaged parts be an option? For sure you'd need: bare block, couple of valves, one bare cylinder head, one piston, probably a piston pin and maybe a rod. Plus all the consumables (gaskets, bearings, bushings, seals, etc). Crank should survive, shouldn't it?

Some stuff you probably couldn't clean the debris out of and should replace to be on the safe side: oil lines for sure, intake manifold maybe, cats maybe.

I have to be overlooking something?

1. Agreed. That will happen as these older cars get more miles on them.

2. Very rarely do you see the person who creates the thread in more than two to three posts on that thread. The other 600 replies are the bickering and pissing match trying to figure out who what where when and why and who works where and can debate better and who is more right and who works for GM.... ect ect.. lol you get my point.

What exactly are you looking to do here propain?

I'm curious.

Because if it is to make one big thread, that nobody will be able to find anything in it.

Besides, my point was, the options for management of this matter, which is really all that is left to discuss about it, as there is no longer any question as to if it exist, have already been discussed, and that was outlined in one of those two options.

Clean up the BS on this forum. Sorry, just cranky watching a good thread turn into a pissing match between you and Mark for the last 3 days and got me to this point.

What can be found in that wonderfully productive thread anyhow that can't be found in the 87 page sticky above about the "Official GM response" I can answer that, nothing we haven't read before. So why the need to pollute every single thread with it?


A consolidated thread discussing the topic would be better. Why must every thread turn into a 20 page pissing match? Quite honestly its turning a good forum into a sewing circle. I'm sure many have either choose to ignore it or not come here anymore because of it.


Someone posts that their car blew up:

"Sorry, that sucks, we feel your pain, Check out this sticky for the info you are looking for"

Seems pretty straightforward to me. But hey.... fight the good fight if you must in every thread. Seems exhausting to me and I don't know how you haven't tired of it yet. :thumbs:

Step 1 attack posters with experience and information in valve threads.
Step 2 complain about bickering within the valve threads.
Step 3 congratulate yourself on mastering the interweb.

I have seen 3 engines destroyed by exhaust valves first hand. Out of 3 of them all 3 had the crank destroyed. One busted in half actually and the other 2 had the rod/rods welded to the crank. Also, you can't even imagine what else this destroys around it. Motor mounts, oiling systems, and the parts that exploded embed in everything from the intake to the exhaust where it's not salvagable. Hell even 1BadBurbs engine wiring harness was destroyed. It's not a pretty sight and very costly :ack:

I think I understand what you mean.

And what information would the sticky contain?

Thanks

Hahahahaha :D:D

I agree but the debate should be over at this point there is a problem. and us members should do something about it instead of fighting with each other.:thumbs:

Ah. The price tag starts going up for a rebuild, then... I saw that a new bare block starts at $3K; a crank would be another $1K. One (!) piston is $800, a bare head is $1K, one con rod is $350 (cheaper than I would have thought). Man.... over $6K and just getting started.

Okay, thanks for the info :cheers:

I think a good first post with everything we know including statements from reputable shops and their recommended fixes.

Completely agree. Threads like the Valve one currently being discussed lose credibility to many people looking for real answers to a real problem if it just becomes a bicker match of who is right and who is wrong.

If you just dropped a valve and came here for assistance would you want to read through page after page of bickering? I know for me it creates uncertainty of who is right and who is wrong.

This is what happened to me... only difference with my thread and others is the 200+ pictures I attached... lol

We of course have this information in here already, but it's not all in the same place.

To be honest, I could put something like that together myself, i.e. list the vendors in here who recommend one method of managing this matter, vs those who advocate another method.

But I don't know that posting that information up in the form of a sticky would send the right message to people visiting this forum.

The fact that such a thread is "needed", and at the very top of the forum no less, so that it can be seen and read by all who enter, i.e. a thread basically giving owners and potential owners, instructions and a roadmap, on what to do for when your motor pops, or worse, what to do to prevent it from popping, is an embarrassment and amounts to an admission that the problem is not minor. Anything but. Certainly won't inspire confidence.

To nail that to the top of this forum, could have serious repercussions on the already reeling reputation of the LS7. It's bad enough, that Rocker thread they have up. You definitely would not want a "Prevention and Management of Popped Motor" sticky thread above or beneath that too.

Worst case scenario, this could have an impact on resale value, as well as impact new and used sales of Z06s of forum dealers, and off forum dealers, and impact their bottom lines well beyond any detrimental effects this issue has had thus far to this point.

I don't see the forum dealers in here, who pay to advertise in here, being on board for something like this.

In short, I don't see such an endeavor, which would basically be a "We're the guys to call for when your motor pops" thread, as being necessarily a good thing.

No, I wouldn't.

But like I say above, I'm not so sure a sticky, basically admitting this problem, is a good thing. On the contrary, if anyone thinks that it is blown out of proportion now, well then a sticky on engine failures, would definitely blow it even further out of proportion.

I would simply want to know "What works so that this doesn't happen to me again", and I would want to know it from professionals who have experience in it's management, as well as private owner's who have experience with it's management and I'd like to know of their outcomes.

I would want to hear from more than one professional, and I would want to know the backgrounds of those professionals.

I would have no use however, for the musing of those who had absolutely no experience in it's management, nor in evaluating outcomes of various methods of managing it, and would make that known no sooner than I stepped in here.

But I think we can get that in a regular thread.

Look at what we have in the stickies now and really it's bad enough. The clutch pedal issue, the head swap how to, the rocker arm issue, and ask yourself how a "popped motor issue, prevention and management" sticky would look alongside the rest of them.

If I was unlucky enough to have my car's engine "blow up" I wouldn't want any of the motor's parts re-used, including the block. Just replace the entire motor and move on. The perception of greater reliability resides in the latter course of action.

For those no longer having warranty, this is a serious economic gamble to take: either fix the heads/valve-train using an upgraded after-market solution, or sell the car if one can't afford to replace the engine if it breaks. And not everyone can, either...

Damn shame...
