How incompetent do you have to be to design an engine that blows up at < 25k and it's not an assembly issue?

Gotta say, these 2011 and newer engines blowing is even more alarming than the early engines failing at higher mileage.

It may be that TWS contributes, but with these engines that fail early, you could probably fill your sump with unicorn tears and it wouldn't last much longer.

0-40 and proper warm ups are the key! I really need to get around to writing my rebuild thread been lazy. My rod clearances were .00125-.00130 (plasti) across the board which were tighter then I wanted but didn't have time or money to have crank ground at the time. Will be pulling pan off to inspect bearings over the winter should have 5-10k on them by then with only 0-40 oil.

[chris719]

Do you really think 0w-40 would allow this engine that failed at 20k to last 150k?

I might buy it on the engines that fail north of 60k, but it seems like this one was doomed from the start.

I feel like it would but its a hard to tell. As it was said earlier some engines are way tighter then others. There also are cars that have close too 200k with 10-60 in them. the 0-40 may lengthen its life but in some cases most likely the damage was already done.

Would unicorn tears offer better cold start protection than TWS?

Anything is thinner then TWS at cold temps so I bet is haha

I probably have one of the early build cars - September '07 - and touchwood so far no issues with 44k km. I religiously warm up the car before I drive aggressively. And I drive aggressively every time. I have done two track days.

I don't even think about the bearing spinning or engine blowing. I will enjoy the car as long as possible. I have no plans to buy the new M3/M4.

I also think majority of the Australian owners pump RON 98 either BP, Caltex or Shell. So do the European owners.

There was an issue with the S54 big end bearing and BMW fixed it. If BMW is not proactively fixing it, then they don't see it being an issue.

Like pointed out in the other epic bearing thread that saw 97 pages and 2132 posts, there is no single issue for this failure. Yes, clearance is tighter than most super cars but it's only an assumption that it is causing the failure.

Can be this the main cause of rod bearing issues?

[chris719]

The last few reported failures have been in 93 AKI states. There are more cars in the US and probably more miles on them due to the cheap fuel to account for also. The guy on M5board.com gets lots of blown S85 engines from Germany too.

This sucks!

Not sure if it's bearings yet but here's my newest noise.

I feel this issue is happening to 2011+ more than the rest. Many of who reported recently have 2011 model. Was there a change in 2011 rod bearing?

Some point in 2010-11 is when the cars started getting the new harder bearings from factory. We still cant pinpoint when the actual time was relative to the manufacture date of the car though. Just because the part number changed on X date doesnt really correlate to how soon they went into the cars.
All we can do at this point is keep track of what cars have had bearings changed and narrow it down.

I just received my bearings and rod bolts and pan gasket. The bearings will go FedEx to WPC today. 08 with 60k and 10W60 only. Will likely change to 0W40 or 5W40 after the bearing change. Hoping to do this job in about 2 weeks.

[chris719]

I think there are mainly two buckets of failures: "high" mileage 08 cars and the newest cars with the harder bearings. With the absurdly low mileage failures on the new cars, one would think it's assembly / tolerance stack related.

I wonder if plastigauge is good enough? Seems like it would be hard to properly measure the clearances working through the oil pan.

8th of hard driving reclining driving. Hard non BMW break in but always warmed up right. Tws for 50k than mix of sometimes 0w40 or tws. Engine purring like kitten and never been stronger. I'll change bearings at 100k and make a big post

I'd like to see the stats.... but I'm assuming that the % of these cars that drop an engine in the first 20K is low in comparison to how many are on the road.

Lots of factors could lead to this type of failure. It's a high performance engine and shit is going to go wrong. That's why they come with a warranty.

Wow man !
That sounds realy....realy bad !
Reminds me and sounds like this>http://www.m3post.com/forums/showthread.php?t=1010787

But your noise is louder and so even worse !
His car is right now at his BMW/Dealer and we are waiting for update !
Said it also to him and so also to you ........
Stop driving your car and take it ASAP to your BMW/Dealer !
You know it...we all know it---> take no risks---> think about our damn bearings !
Don't wait after a hole in your engine !
Last week i saw one on here of end 2013 with "6700 miles" on it ,yes actualy a brand new engine ---> it was over and out !
So again take no risks man !

This definitely doesn't sound good. May I ask what octane you've used? I'm unfamiliar with Perth's choices but there was some controversy surrounding low octane and bearing failures.
