Come now, that's just absurd.

Instead of your conjecture, why don't you do some digging and find a little evidence to support your claim?

Oh yeah, there was that pesky detail of an accident...a rear-ender, no less.

Who knows what happened to your car...I hate to say this, but I don't give a $hit at this point. What bothers me is your blanket assumption as evidenced by this thread title. The truth is this: YOU don't know what happened to your engine either...and you post a shaded factoid: it is a LN bearing...you had a failure. So you ginny up a saltry thread.

You leave out many facts in this thread title...
What taper?

I don't get you, bro. I come back and see more blown engine threads and more IMSB theories. At least this time there's a new theory. Glad you haven't changed.

Well, Bro, maybe I can help you "get" me. Posts like these from a guy who ditched his (perfectly functional) 996 because he couldn't handle the pressure of a car with known issues irritate the hell out of me.

If you don't have anything good to say about the M96 or the cars it's found in, GTFO. Seriously. Why do you enjoy hanging out here and trash-talking a car you couldn't handle owning? Go find some other bridge, troll.

Aloha, "Bruh."

Get the f*** out of here. We are here because we love our cars. Every mile I put on my green mean machine puts a smile on my face, and for the few people who have had bad luck with these cars there are hundreds of thousands of others who love them and drive them without fault. I will never sell my 911.

Yeah, KK, I gotta tell you that this wasn't your finest moment. I appreciate your humor and the "stir **** up" mentality keeps things interesting around here, but give it a rest. If it's just gonna be a constant stream of 996 bashing, then take it somewhere else.

I think you could really gain some traction on the Maserati forums. I seriously considered buying a 2002 Maserati Spyder at the auction this week until I read their forum's buyer's guide. It seems that if you go too fast over a speed bump you can damage a catalytic converter that costs $12,000 to fix - on a car whose estimated pre-auction value was $11,150. So see, I'm not just bitchin' about you, I'm offering a win-win solution. Besides, those rich Maserati guys are wound way tighter than us poor ol' 996 types, so I think the potential entertainment factor is way higher, too.

Guys, no need to beat around the bush; you would probably benefit from being a bit more candid!

Just for the record.

Jake has said he has recently identified a manufacturing tolerance issue in some blocks which he found by investigating multiple failures on the same block. He now uses a special tool he designed to separate good blocks from bad blocks. He will only rebuild good blocks. He plans to sell this tool when patented.

So it would seem it is entirely possible for the LN bearing to fail at 30k for a reason external to the bearing. The LN bearing could, under this scenario, be superior but fail due to uneven forces applied on it for which it is not designed.

May not be relevant in the OP case as the original bearing lasted 54k miles with no issues before it was preventively pulled out. You would think the original bearing would have failed long time ago if the block is misaligned.

The original bearing was a deep groove ball design. Deep groove ball is more tolerant(in theory) of misalignment than a roller bearing . That is why I hesitantly mention using spherical bearing again.It would be useful to discuss defects in this alternative for the few unfortunate enough to have this potentially expensive and presumably recurrent need to replace any of the current IMSB options.Just when we thought we were able to offer a long term solution to the IMSB issue ,it pops up again.
Without a method of measuring the 'misalignment' and without any standard tolerance to compare to ,we'll just have to wait for Jake to show us?

To be clear, the plain bearing, (IMS Solution) did not fail in this thread. There have been ZERO IMS Solution failures.

The IMS Solution is THE MOST tolerant of misalignment issues related the crankshaft/ IMS centerline than any other technology.

Just wanted to clear the air there and make sure that everyone understands what failed. We will never know how it failed because the core that holds all the data is just being recycled to be sold to someone else. If it has a problem the next guy that finds it is the one who will buy it.
