I certainly share the same feeling. I'm also annoyed about the aftereffects of these components.

In my opinion, they use the customer as their R&D department..


Plenty of companies do this. Microsoft Windows for instance sends bug reports to MS when an application crashes. Same concept.

But your computer doesn't overheat and ruin parts inside if this happens.

Update:



I got a customer's motor today that was suffering from the intermittent overheating symptoms that I'd listed prior in this thread. Infact, some of the symptoms I was complaining about were from this same motor.



I tore it down today and, not to my surprise, it had failed due to the exact reasons that I suspected: All four of the inner water jacket o-rings (the RA teflon-encapsulated silicone ones) had breaks in the teflon jacketting around the silicone core in various places; namely from TDC all the way around to BDC (bottom dead center below the intake ports).



Attached are several pictures to illustrate.

I think those ports look great! Also glad we have the anwser. All the hours upon hours of testing double-triple checking everything is finally over!

I have another customer with a 3rd gen and 13BREW that I built with these same o-rings that's bringing his car up sometime in May with the same symptoms.



Nobody can tell me with any level of confidence that I installed these o-rings improperly. Nobody can dismiss this as some sort of fluke or whatever the "0.001%" comment thing was all about. This is what's happened and I suspect the four-odd motors that I've built aren't the only symptomatic motors out there.
