Blown engine??? Post up
If your engine has blown please post it. I for one had mine blow but seems like we have a few others. I'm just getting a count because seems like some on this forum are making it sound like way more than there really is. To date I've been told by the team that took my car back 13 engines out of like 8k plus z06s made
so heres the list
1) NORCALSS
2) lawdogg149
3)walhan_qtr
4) zrace2
5) car tested in magazine

There is little difference between the production methods for the hand built engines and the production ones other than where they are built and a few assembly details. In most cases they use identical tooling. If the so called production assemblies make any increased use of automation that would tend to make them a little less likely to have build issues. Robots don't make mistakes like humans do.

Reason for Blown engines?
Was there any explanation as to what happened? Lawdogg said oil issue? Have to question that not using Mobil 1 can blow an engine! Really. Did you guys race the car before 1500 miles or do any tinkering with the engines?

The Z07 motor uses just as much automation the difference is not as many people involved in the assembly one person responsible through the process of the build

The question regarding who built the blown engines has not been answered. Of the supposed 13, so far I see 2 on this post, both built by an individual. The most recent blown which was driven by the press also appear to have been a Z07 thus again built by an individual. I too would opt for an automated build, not only for engines, but paint etc.

You know the new 2016 Cadillac CTS-V uses the same engine as the Z06? Slightly detuned, but same engine. Theirs aren't the hand built ones, and they only run automatics.
You might want to check their forums and see if they know of any engine issues there, too, since you want to capture the universe of blown engines of the same type.
Just a thought.

Well if it is 10 engines of 10,000 pretty low. .001 percent! Sounds like no worry unless of course you have unlucky and landed in the .001 and some of those 10 we don't
know but a few could have abused the car too much too early.
We know cars with 37 miles on the odo have been to the strip with all out passes at 37 miles. That one didn't fail yet.
These cars have coatings on the bearing's that needs a proper breakin for best results. The 500 mile break in oil is fine. Is not a issue.
There is no issue that I see so far. I do think the 1lt has oilling issues
the lt4 is better in my book

I have one on order and the ZO6 forum is the only thing keeping me informed on the LT4s!! Cant wait.
OP, unfortunately I don't think you will get all or even close to all the documented blown LT4s. As Im sure your aware not all Z06 owners are on this forum. And forget about asking GM they wont give you that answer.
I really think it just came down to quality control and metal filings they were not cleaned out properly after the machining of the crank shaft oil galleys and so on. At least I hope.
If its the human error of the "hand built" engines I still find that hard to believe as all the tools they use for torquing things are pre set air tools.

GM has not even built one CTS V for the consumer yet. Builds start Next Monday. Also the engines aren't "detuned" they have more restrictive exhaust manifolds thus the loss of 10 HP.
