So you produce a sh*t product dress it as lamb and sell it for an exorbitant price. Then when the wheels fall off maintenance etc floods in the owner/s get pissed off sells it and doesn't buy another one. If that is all true how have they managed to stay in busy for so long? what is missing because most company's would have been done years ago especially in the competitive auto industry.  

because they give you a comprehensive warranty from new so these major failures don't actually cost you apart from downtime ,it just makes them bad second hand time bombs and because all the euros are similar good luck finding one thats much better.

Incorrect. The S54 E46 M3 had a connecting rod bearing materials fault not a clearance fault like on the S85 and S65 Motors. The S85 and S65 motors, some have 150-200000 kms on them and are fine and some have 3000-5000km on them with engine failure. So replace your connecting rod bearings with the BE Bearings product ASAP for peace of mind and for proper clearance and oil flow. I've done a few cars here in Bahrain and most of them had abnormal wear for the low mileages they were at. Some info on BE Bearings taken from their website:

Background:

  • BMW M5 (2005-2010), BMW M3 (2008-2013) can suffer early bearing failure due to inadequate rod bearing clearance.
  • Insufficient clearance means insufficient oil flow, excessive bearing surface heat, and premature wear.
  • These symptoms can lead to early bearing failure and a very expensive engine rebuild.
  • Problem can be addressed during engine rebuild, but it's expensive.
  • Some people switched to thinner oils -- as a stopgap measure.
  • Other stopgap measures include anti-friction teflon coated factory bearings, WPC anti-friction treated factory bearings, and custom bearings with same clearance as stock.
  • "Coated" factory bearings decreased clearance.  This is not a good idea.
  • WPC treated bearings slightly increase clearance, but are a stopgap.
  • Custom bearings keeping factory clearance doesn't fix the problem, but allows you to track lead and copper in Blackstone oil analysis.
  • Newer factory bearings (2010.5 and later) are made from tin-aluminum, not lead-copper.  Tin-aluminum bearings are 4-times harder on the surface than lead-copper bearings.  This extra hardness shows signs of doing more damage to motors as there seems to be more bearing failures with 2010.5 and later vehicles.  Tin-aluminum bearings also don't show the same signs of premature wear in Blackstone oil analysis due to lack of lead and copper.
  • A better solution was needed.

Better Design

  • Designed to address and fix the rod bearing clearance issue.
  • Designed for use with factory 10W60 weight oils.
  • Increases oil flow.
  • Improves lubrication for "Start-Stop" vehicles over factory bearings.
  • Designed in consultation with leading industry experts from  NASCAR, Indy Car, and former BMW M-Division engine designer.
  • Designed and manufactured by Clevite, factory BMW bearing supplier.
  • Traditional lead-copper bearing design; less wear on crankshaft journals, traceable with Blackstone oil analysis.
  • Each bearing is measured and size-binned.  Allows for custom bearing selection when necessary.

Never had the time to study the e46 failures. 

 

They just seemed to have a period of bearing issues.

Yes and BMW issued a recall to swap out the bearings with bearings with different material. Never an issue with Oil clearances.

Know of E46 M3's that where not part of the recall having major bearing issues last year.

Yes, but this is not because of clearance issues. Either wrong oil is used by owners or oil change intervals are very large instead of the usual 5-7000km or 5000 mile oil changes with a suitable oil like Castrol TWS or EDGE something 10w60 weight. Also the Rod Bearings on an E46 M3 are now considered a service item, change every 100,000 miles or 125,000 km's depending on varying conditions and use.

100,000 miles or 125,000km?

 

Either way, a service item??

Those are just estimates depending on use but yes the S54 bearings are considered a service item now. You can find out a lot more on m3forum.net if your interested.

Any engine derived from a race design should consider rod bearings as a service item, among other things.

Yeah ^

I've always understood engines with race style clearances and construction take their toll on sacrificial parts like the main bearings.

So to get ~ 100bhp/ litre, you have to rebuild the bottom end of the engine as a service item? Pffft!

Not necessarily the bottom end - That implies a complete dissasembly of the moving parts in the block.
