This one was not a stock engine. It was a forged engine with aftermarket REV SS exhaust valves. If you look close you can still see the intact intake valve still in place. I was surprised to see part of the deck gone. This happened at the top of 3rd gear on the drag strip so engine speed was say around 7K or close to it. So if you think you are safe with solid SS valves, think again. You maybe a bit safer but certainly its not fail safe.

What guides were in the car? Will you be doing the breakdown and inspecting the heads?

Nothing is fail-safe at 7,000 RPM.

propain

hahaha... gotta love it.

ghoust

Details on the service of the engine..how many miles / passes thru dragstrip / hours on track were on this setup.

GMuffley

That truly sucks.

Not to worry its Quick to the rescue

Thats 2 SS valves down for the count this month alone. Not looking good.

What are we looking at, can't quite figure out the orientation.

I think this is Madsen's car. The one we knew about a couple of weeks ago.

So I am only aware of this one.

I said it before. I'm glad mine are WCCH heads.

Quite possible. I believe he said the vendor who posted this had his car.


Good! Maybe we can see the tear down now.

'06 Quicksilver Z06

Yes, tj Wong has Madsen's car now.

I know of one said to be SS valve failure in here from a few years back, in a car belonging to a forum member..

And from what I can tell from the posts, out of the same shop that did the work on Madsen's car.

Also why I don't believe that this is a geometry issue which roller rockers can solve.

It's threads like these, that made me do what I just did about today, and hope others do.

I've sent a request to a moderator to have all threads like this merged into one and made a sticky thread at the top of the page...

a sandbox per say for people who keep wanting to debate this issue over and over and over and over and over and over and over and over

the 1000000 threads we already have on the SAME subject.

The sticky would also be a resource for new comers to this section so they could go do their own research and make decisions if they want to do something. ..vs starting yet ANOTHER valve guide related thread.

________________________________________ _
Above said, nothing is indestructible . I don't think any shop or any member who switched over to SS valves thinks they are indestructible or are not subject to blowing up if not driven, tuned or installed properly. Quite honestly, I could see 5 more fail with SS valves and I would not care. By the day, this forum loses credibility to me, we never get the whole story or facts or history of the car. rarely..do we.

propain

Well see what the future holds. To soon to tell.


TI is a great shop from what I have been told, for him to make a post stating that "So if you think you are safe with solid SS valves, think again" knowing all the details, I would listen.

Bronze guides are in the heads, I removed the "good" head yesterday.

Its had a few passes on the car, I would say less than 25 since the build.

Yep, its my friend Steve from Central Oregon.

jedblanks

Post it two more times so we can up the count to 4.

propain

Thanks for the reply. I look forward to the results from the "good" head and the guide measurements.


How many miles on the car since the build was done? Excluding the track time.

I agree it would be nice to be able to manage all of this stuff but it won't work. The thread would be so large you couldn't find anything in it and the amount of misinformation in one place would be overwhelming. Sort of like the Service Active Handling sticky that is so full of misinformation.

Better to let there be separate threads that come and go and are easier to scan through since they don't get too big.
