Crankshaft bearing issues with the BMW M3 – S65 engines

The dreaded crankshaft bearing issues with the BMW M3 – S65 engines. Let’s get the facts straight, the actual failure rate is extremely low considering the volume of cars built over the five years, approximately twenty six thousand  (2008 to 2013 ) for the general public.

This particular engine has been built as a high revving normally aspirated high output performance engine pre-dominantly designed to compete with Porsche in the various road races over the years.

The first examples were squeezed into the E46 chassis. E46 chassis where they became legendary in Europe and North America. Worth to note, the same engine has been the sole M BMW Motorsport of choice in all the factory supported M race cars the M3 and the MZ 4 from 2005 until  2015 which speaks volumes about this particular engines durably. Its safe to say the engine is well built to perform. It preforms very well under racing conditions, and performs just as well under daily driving over the life of the engine perhaps.

However, there are a few things to remember, if you own one of this cars for instance the bearing load on the connecting rod will increase 25 fold from six thousand rpm to eight thousand five hundred rpm.

Because of the high revving nature of the engine we recommend to switch from the factory recommend TSW Castrol motor oil to the more robust build Liqui Moly 10-60 motor oil. Furthermore we also recommend to shortening  the oil change intervals to maximum ten thousand kilometres at most.

Also we ad (despite that BMW not endorsing any additives at least not on paper) a Liqui Moly MOS/2 (molybdenum disulfide, graphite) additive which gets embedded in the bearings at each or at least every second oil change.

If you have oversized calipers and use your S65 equipped M3 for competition purposes you should convert your lubrication to a dry sump system, regardless of cost. The factory set up not designed with extreme G forces in mind period.

We have serviced many of this cars with this maintenance method, and never had a bearing failure even at spiritedly driven M3 cars at near two hundred thousand kilometres. Draw your own conclusions.

2016 BMW 750Li xDrive

While the BMW M3 that steals the limelight in the new Mission Impossible film, we should say few words about the the new BMW’s new 7-Series.

BMW’s new 7-Series has finally landed, bringing with it more space than ever, loads of technology and powerful yet frugal engines.

The car will arrive to North America very soon, as a 2016 model, initially in 740i and 750i xDrive variants and with the long-wheelbase body style only.

This is the sixth generation of the luxury icon, and while it may look a lot like its predecessor there’s an impressive number of innovations that have taken place under the skin. At its core is a new modular platform codenamed the 35up. This platform will form the basis of most of BMW’s models going forward and includes carbon fiber-reinforced plastic (CFRP) in its construction.

The 7-series new platform contains some major changes. What BMW is calling its “Carbon Core”, it is a mix of carbon-reinforced plastic, aluminum, and high-strength steel.

It also allows for a number of other technological advances including electrified drive-trains. Than beneath the conservative BMW exterior, there are some major changes.

An impressive new thing is, the driver standing outside the vehicle while the new 7-series parks itself. Unfortunately this feature will not be available in Canada at this time, instead, we’ll have to be satisfied with the parking-assist system. This system can maneuver into any parking spaces.

The search for pioneering innovations is the driving force for the BMW engineers. BMW’s new 7-Series comes with functions such as BMW Gesture Control, BMW Laser head light or the above mentioned Remote Control Parking.

These features set further future orientated standards in the BMW 7 Series. In addition, with BMW Touch Command, a tablet for controlling key functions has been integrated into a BMW vehicle for the first time.

BMW has said that all its core model lines will offer a plug-in hybrid, and so it will be for the 7-series too. A diesel  7-series also a possibility at some point. A new plug-in will carry the hybrid banner.

BMW M3 Coupe

BMW M3 CoupeAdditional schooling is not enough to know cars to perfection.

When we encounter a brand new BMW or any other high end German import car, we pay special attention to the changes.

For example we take photos of interesting developments in the late model cars, so will be ready for our customers when they need our services.

No misunderstanding please, we do not disassemble anything, but visually we get accustomed to important changes, plus the additional, targeted  schooling, we will be at our costumer service when they need us.

Nice Touch…

Be careful, some retailers claims, you can just remove the front glass on the speedometer.

This is absolutely incorrect… so as the owner of this fine BMW M-3 found out after braking his own instrument cluster.

Needless to say he wasn’t amused when he found out the cost ($ 900.00+) for a replacement instrument cluster. Naturally we got around it and fixed his car up with his new carbon fiber insert at the same time.
