And now I know why we've been seeing broken rings in 9a1 engines with less than 5K miles...

I didn't see any beer sitting around?!

When Sherryl and I went and visited the factory years ago we saw cases of beer on the shop floor!

I like the ring compressor tools they use ... something wrong with them, Jake?

And no safety glasses in the bunch...

Not much oil in the assembly....

Not much whistling while they are working either...

Looks to be the same/similar to one that was posted a couple days ago.

curious why you say that, and I was under the impression that break in was now being done with forced air to make it cleaner and faster.

If you see a glaring issue, you should reach out and get a consulting gig with porsche....that would be a great gig for you....just to do it.

Here's one example. 4,165 miles on a 2012 Cayman R. This was an engine that was original equipment in a one owner vehicle that never even saw it's first oil change, or a single day at the track. It came to me to see my 4.2L power plant that was built from the original 3.4. This was a build that was a mirror image of "Cayman X", that was featured in the December 2013 issue of Panorama, pages 66-71. Upon disassembly I found this, and then it made sense why it was down 25HP on the dyno when I did it's "pre run" before taking it apart. No one expected that it had an issue, and I found a lot of surprises. Today it makes 350 at the wheels, up around 100HP over stock.

Faster and easier will never be better than "built by hand".

One observation that I made:

Anyone who works on these OUTSIDE of the factory has far more skill than the ones who work on the assembly line.
My guess is that very few of those in that video are truly skilled auto workers, most of them know how to do just one or two things on the entire engine.
I also noticed the no safety glasses part.
And I am sure that they were instructed to pickup the beer before filming.


This reminds me of the tour of the Saturn-V launch control facility Museum at Cape Canaveral.
We watched the whole presentation and the lady said "and we have matched the real control room with 100% authenticity" it had coveralls from all of the contractors draped over the chairs and clipboards with pencils, etc.
She overheard me tell my family "Well they missed ONE thing"
She looked at me and "What is it that you believe we missed??"

I said "There are no ashtrays......"

Made me think of terminator 3, the robot assembly line......

It's understood that more care is applied when built-by-hand, but how's that going to happen in this case? (new car from the Porsche factory).

What seems to be the root cause? ... are they not sizing the rings properly or not enough lube?
