hang on jim,
i think youve missed something important here.. hans screw up was actualy part of a plot by rear engine lovers to subvert the course of 928 history! the plot involved a well kept secret that they had substituted mismatched rods to all the 928 engine 2/6 caps.

Hi Jim,
I am glad you took a couple days to completely muster your resources.
Danke, gleichfals.
Yes, I was feeling a bit quirky that day, I'll admit. Mr. Simard had just commented in a totally different thread asking about 928 lifters that he thought I should not comment on 928s at all.
My position in that thread was that technology used by Porsche would be similar to technology used by other car manufacturers. I had a Suzuki lifter of the same vintage and took the time to slice it in half to be able to compare it.
When I erased my comments in the thread Mr. Simard then erased his remark -- surprise. Some time later when he noticed that I had done some more editing he was quick to try to distance himself. No problem. I cooled down a bit and went back to the thread about lifters and, wonders, I was proved correct. It is not that dramatic a thing -- simple logical thinking about contemporary technology and how it develops over time in a field. You probably have not noticed but that is exactly what I do with windage control.
I do take what I do seriously. I focus on problems and think about them for days, months, years; in some cases, decades. It's a pity this is novel to you and you feel the need to criticize others for it.
You conveniently leave out the facts, pointed out by others, that the factory tours of that vintage were eventually cancelled and one of the reasons was the workers were being distracted. When you have a chance to further your education with some cognitive science look up short term memory and the effect that distractions have on it.
Furthermore, you loudly complained that it was impossible for such an error to occur and stated that the morphology misalignment I was noticing was common. I asked you -- and anyone -- to show me just one other example. You never did despite having months to do so. I call that being full of hot air.
Contrary to you being all mouth and no substance, I took the time to show how -- even from one engine -- caps could be mismatched, complete with photographs and measurements. I also pointed out that the misalignment in some cases was so slight that it could not be accurately discerned by the human eye. This level of misalignment would probably survive and bed in with a stock engine conservatively driven at the beginning of its service life. In an engine that had fresh bearings heavy use would be fatal. And so it was.
Your skepticism about the odds? Well, that's nice -- I rather think it is better to accept empirical evidence for what it is.
How wonderful that an exemplar of the very same mistake would turn up in a Formula 1 rod of the same basic design, manufacturer and manufacturing method -- undergoing far more scrutiny -- to make you look like a fool. Yup.
You then argue that the production manager of the company that made both the rods doesn't know what he is talking about. Right.
You then demonstrate a complete ignorance of the rev limits of the stock rods in question. This on an engine that you put yourself forward as an expert on. Wow.
Yes, the re-examination of the failure in Dave's engine -- by closely scrutinizing the pictures that HE took and I saved for two years -- was prompted by the bearing failure in the classic spot whilst running my system. When and if you ever take a course in formal reasoning you will learn about making working assumptions. You have to go beyond knee jerk response that EVERY failure in the 2/6 position is from the same cause. Dave admitted that he did not bother to resize any of the rods that had done over 100,000 miles -- this was a race engine built on the cheap that failed. If he had simply done that common (standard?) procedure then the misalignment would have been obviated.
Really, is there anything else you feel the need to say that will likely embarass and denigrate you still further?
Yikes.
Start taking thinking about the engine you make a living off of as seriously as I do.

It was quite funny when you felt the need to go back over all your posts and delete them thus depriving this forum all of your "expertise" . That was however one of your least foolish actions.... I think you might take yourself a bit too seriously.

(...) Now what was your original premise ....Oh right there was a factory tour going on and Hans distracted by the sight of a pretty lady dropped a numbered rod cap and when he picked it up fitted it to another rod with the same number a 1 in 998 odds happening at best assuming the rods are stacked in a bin with the caps not attached ...

....that was then assembled into an engine which ran fine for 20 years..... Then on a rebuild for a 300 hp "race" engine that same mismatched rod cap was re-installed with new bearings only to quickly fail ....in spite of the fact that it had one of your scrapers. Which lead to the statement that an F-1 engine was based on the 944 then became it used 944 rods, then sinter forged rods. Frankly anyone who sees a any real similarity between the 944 rod and the F-1 rod which is about 1/2 the size has gone beyond the absurd. And in the end what difference does it make how that F-1 rod was made? It has nothing to do with the fact that one engine with your scraper setup failed. Was it caused by the scraper ? nope....does the scraper fix the 2/6 oiling problem ? ....
Yikes.

Actually Kevin I wanted to see how far out on a limb you would take this " working assumption "
I could be mistaken but isn't that F-1 rod being sold as a collector item never intended to ever be used ... The " I am glad you took a couple days to completely muster your resources. " is another flawed assumption because I tend to view your comments as somewhat amusing but find it to be mostly a waste of my time.

Taking on Jim B. of 928 Int'l, whom is know and respected by most, if not all, in the 928 community is just plain foolish.

It is a shame that you don't have enough class to admit you are wrong too.

As I mentioned in the past, you do no service to yourself by making these posts. Prospective customers will just wonder more and more...

Maybe prospective customers should wonder more and more. That's fine with me. As I said, I take what I do very seriously. The BMW scrapers we supply to the spec E30 series have gone through eight or nine generations of design. It is a great way not to make money but to me it is important.
For three months a thread was allowed to continue on this forum that was an express personal attack. No-one notified me. I did get one phone call at the time that in retrospect was probably to see if I was ok. That gentleman advised me to stop wasting my time on the forums. That is probably the wisest advice I have had.

Randy made a similar strange comment when he ended my reply to it in less than a day. If someone mentions you in a new thread you do not get automatically notified or subscribed.
I will try not to ignore it.

Kevin, you seem to be an intelligent guy. You seem to know quite alot about engine design and the like. One thing you lack however is tact. What good does it do you to be right if no one will listen because you insist on beating them over the head with it? Learn a little humility and it will serve you well.

"Tactful" on your part would have been to send me an email and ask me why I erased the posts. I would have been happy to tell you why. You have and practice the same qualities within yourself that you criticize me for. Just more subtly, more passive aggressively.

All this struggling and striving to make Jim Bailey and the forum understand, is a great mistake; not because it isn't a good thing to impart knowledge if you know how to do it, but because striving and struggling is the worst way you could set about doing anything. It gives a man a bad style, and weakens him. It shows that he doesn't believe in himself much.
