Holy crap Macster,
that was a hell of a write-up on one topic, the piston/bore relationship during different expansion rates.
What you are saying is probably more true with Aviation engines than car engines? Recip. engines have a design feature built-in where the top of the bore is tighter than the bottom so once at operating temperature, the bore is relatively true.
I was just talking about all the "other" components.
Bruce and Jim, carry on....................

But you don't follow the manual.
All people have to do is look at you posts and it clearing shows that YOU DO NOT follow all of Porche recommendations. When you calm down, I think you'll realize that.
Are you off your medications?
BTW, if you are going to try to impress me with a foreign frase, you should at least get the spelling correct.
I'm no going to bother with you til you sober up.

And, as usual, entirely devoid of proof or cases in point.
Sorry about misspelling 'erat'. If only your English was as good as your Latin.
Man, I could bait you like this all night if I was the mean sort. But I'm not, and I have to hit the road anyway. Peace out, brother.

Absolutely hilarious post. 'foreign frase'. Classic. 'Porche'. Gold. '... look at you posts and it clearing shows.' (Even you may want to edit that one).
And, as usual, entirely devoid of proof or cases in point.

Especially true in 2-cycle engines.

What I was talking about was seizing arising from sudden influx of ...
cold coolant.
I've seized a two-stroke engine when running wot with a high compression head installed. Engine didn't seize up solid, but slowed down a bit and when I closed throttle some engine cooled enough to free right up.
Anyhow, with other cars I've seen a pretty drastic temperature drop when the thermostat opens and allows a slug of cold coolant into engine.
These other cars has cast iron blocks though.
However, I have checked my Boxster's engine and its real time reaction to when the thermostat opens after starting engine from cold (below 32 degs. F. and sometimes even in the 20s or teens) and so far the thermostat opens very gradually.
My concern is that maybe with harder driving the opening might be more sudden and thus the temperature drop more sudden/severe and excessive engine wear could result.
Thus, I do, as I touched upon above, do allow engine to gain some heat and then when I drive away keep engine speeds/loads down until engine fully up to temperature.
Sincerely,
Macster.

I'm just saying to this guy, if you're getting conflicting advice, default to the manual. It's good advice, even just based on probabilities. The manual is bound to be right more than half the time; bickering strangers on the internet, well...
As for the rest of your post, I have to say that sometimes you make me think you must have been fired by Porsche at some point. I'm not going to get into a quality argument with you here; nobody is disputing that these cars exact a price in mechanical quirkiness for the pleasure they provide. If you don't think it's worth it, don't drive the car. As for them "admitting" their mistakes, well, it might surprise you to learn that all car companies are constantly updating their products, mid-series, even mid-year. This, alone, proves nothing about Porsche's supposed malicious incompetence.
I repeat my question: Why do you drive one? The bashing is just a buzzkill and, as I say, makes me think you have an axe to grind.
