Freedom of speech is guaranteed by the US Constitution and applies to US citizens who would like to criticize the Government, etc. without fear of retribution. Freedom of speech does not apply to private businesses and car forums.

For starters, you're British and have no US rights. But even if you were, the 1st Amendment to our Constitution doesn't apply to a private entity such as a car forum.

But even with that said, nobody is trying to muzzle you. I like seeing you make up stories while refusing to explain them. That serves my purpose far more than keeping you silent.

Its being discussed on the Bearing "Wiki" thread...feel free to join in.

I have read all of Regular Guy's research postings and threads, even before my engine went south, and I have to say that we should be grateful that he took the time and data- presenting it in the way of non-bias and evidence based approach as he did...

I also agree that knock detection system on the E92 M3, and including the E46 M3, are too sensitive to allow for that much detonation to spin bearings.. I could see one crank revolution of knock before the ecm would pull back enough timing to stop it before the next engine revolution, if even that much... Its not enough to cause the substantial damage we are seeing to not just only the upper halves but also the lower halves of the bearings as well...

I am also certain that if detonation were the issues with these cars we would certainly see more cavities or tiny craters on top of the pistons, which we have not seen...

Regular Guy at least has us all heading in the right direction based on the evidence to isolating the problems with our rod bearings... His research has at least eliminated all but a few problems that appear to be contributing to this bearing issue... Tolerance stacking/Bearing clearances, Oil Supply/Pressure, and Oil properties...

Could be a little bit of all of them or just one, but at least we have a better idea of where to apply our preventative applications...

I knew a long time ago when I started getting into european muscle cars that they would come with a higher price and sacrifice... I have been driving M3's for the last 10 years, and I must say that I still think the E92 M3 is the pinnacle of the product line, even despite getting my ass handed to me two months ago when my bearings disintegrated...

I still love this car and its qualities, so I am thankful that someone took the time and research to at least come up with a formidable measure to figuring out exactly what is causing the bearing issues in the M3s and M5s...

I'll add you to the crony list. Soon, you'll start getting my crony newsletter, and I'll put you on the crony list of people I need to go out and attack when a non-crony posts an opposing point of view.

Where is my crony newsletter? I didn't come in the mail today.

You seem hell bent on scaring people away from using thinner oils, and keep undermining the hypothesis that bearing clearance is the cause for engine problems. You don't even have a hypothesis of your own. You tried the whole crappy gas/octane/detonation hypothesis but that didn't hold water. We have one good working hypothesis from RG that is supported by the bulk of anecdotal evidence. DO you have a better explanation? Or are you disagreeing just for the sake of disagreeing?

Good breakdown Petros! .....you did forget the #1 point RG made.

"1. You're not an expert in any of these areas."

............wait a minute!? There's a crony newsletter????!!!! I feel so left out....

Sheesh, so many people want on the Crony newsletter mailing list today that I'll have to start automating future editions.

I'm sorry people are so dismissive of detonation as a least being a contributor to failure. We have seen the pictures that speak for themselves:

1. Upper bearing shells showing more wear which would coincide with detonation pushing the (little) oil film that's left out of the bearing shell area causing the wear noted.

2. I myself hear/heard knocking from several different cars from bad 93 octane gas. The super knock detection system obviously wasn't pulling timing quickly enough as it should. Remember, audible knock is very bad as it should be corrected by the DME before by ears hear it.

Can I get on before you start charging money?!

So what do you think is causing this? bad fuel all around or bad DME design?

S65/S85 knock detection is somewhat unique to the BMW line I believe. Maybe it's time to go back to good old audible sensors like the S62?

On another note, I wonder what the spark plug maintenance has been on engines with extreme wear, as well as their condition when the engine was taken down.

My spark plugs were changed at 40k miles, and my engine failed at 56k miles...

It's evidence vs anecdotal experience. Are you in the medical field? The systematic approach is pretty impressive.

Fwiw after finding out about the bearing issue I ended up buying extended warranty when originally didn't plan on it.

Regarding shop replaced bearings, its striking that essentially every single shop set pulled seem to be on the verge of failure yet the vast majority of diy pulled bearings are not.
I guess showing pictures of pulled bearings in decent condition is not going to support the illusion that every single M3 is on the verge of bearing failure and should have their bearings replaced post haste..
Except for the Maleks customer car of course.

your thread on getting your engine replaced and your comment on third party vs BMW warranty was what convinced me to get it. to your patience and perseverance.
