E63 M6 bearings

[thireshan]

Hi guys

Can someone advise which make of bearings are advisable to be put on these cars and whom in cape town i can contact to get this done.its a preventative measure for a car im purchasing.

Thanks in advance

Oem bearings are normally the choice on this forum. king race , acl or vac is generally what the European guys go with

BE Bearings with OEM rod bolts(new of course), finish and kla

Like TUTU says:
BE Bearings if your budget allows as they have addressed some of the known issues.

Second option is Agents.

If you go the BE route get ARP rod bolts if not get OE bolts.

Peter would you then run the car with these bearings with confidence for hundreds of thousands of km's?Or do another change after 100 000 or so? Also would you change to a thinner oil?

Clamping tests have shown that ARPs tend to warp the shape of the rod, whilst they do offer the greatest clamping forces, I don't think this a great trade off.

OEM bolts have been shown to provide the most clamping force without distorting the rod

Just No, other than having a new crank made to increase clearances and tending to the detonation issues, changing bearings doesn't solve the problem, but caring for the motor PROPERLY, once bearings have been done, will extend the life of the engine.

It's a costly exercise for peace of mind, but worth every penny when you get behind the wheel IMO.

If I was racking up mileage on my car, I'd do bearings at shorter intervals, just to see what the wear is like, ie 100 000km, then 80 000km, then 60 000km and so forth, just to better understand, this obviously only with a beeeeeg budget

Would run it to 200 000 Kms with those bearings.
Provided the engine is hot before being driven hard and oil changes happen every 10000Kms.

I might then use a 0W40 with Ceratec for added performance.
I am not advocating that others do the same merely my opinion if I were to drive one.

I like the idea, I just don't like the increased temps

From learning on this forum, Buying a second hand M car definitely needs new bearings no matter what's the mileage because you don't know how the car was treated, warmed up, oil services etc. also once done you need to take care of the car, warm up the engine, do regular oil changes

Also do a gearbox check / service. I just found out brakes on an M is like 30k

Wow makes me wonder if I will ever be able to afford any M car.

True. If you treat it right, service regularly and don't hammer it from cold it helps.

A full OEM brake job on almost any performance car costs a lot of money. 350Z and STI both just below and just over that number for smaller discs and pads. There are alternatives like powerbrake etc. The last order of business before a car goes off plan should be brakes. Its why you see guys recommending that you take into account whether brakes will be required in the period before extending plan (If you are paying 30K for full cover and you are pretty much guaranteed at least a 36K brake job out of it, why would you not extend?)

Same for OEM suspensions.

You are right that first order of business for any car is service regardless of what history says and all preventative work done before even thinking of modding. Learned this the hard way!

Approximate pricings on the BE bearings and oem bearings and all the other needed stuff as mentioned above?

 

[Peter@AEW]

All in
Budget R30K for OE and R40k for BE.

Ok..have they not changed the specs of the bearings for better clearance? Sorry i am not as technically minded as you guys but i am trying to get an idea. I read somewhere that measured OE bearings have changed over time & there is more clearance.

They have changed the construction of the bearing on LCi models(eliminating lead and copper) not the structure, already the OEM bearings are too narrow for this motor

 

[individj]

i see Tune Tech are of the opinion that the stock bearings don't have enough clearance as in its too wide.

 

[Waseem 333i]

Nope they are too narrow

 

[922-ZN]

They are too wide for the crank, but as a whole, they are too narrow for the application, narrowing the oem bearing to increase clearance will be catastrophic.

Man am I glad I don’t have an S65 anymore :roflol::roflol:

Seriously, just stick to the OEM Bearings. They do last long if you don’t drive the car like a plonker. Think of it as a maintenance item and don’t agonise over it too much.

I was of opinion that this bearing issue is just the natural aspirated M cars from e46 M upwards , but on Saturday I was at a friends workshop and there was a X6 M[twin turbo V8 ]with a bearing knock , they already done new turbos , then the knock , motor was stripped on the bench , needs new crank , when I enquired how much to repair , the parts-bill alone comes to r150 ooo , but this includes cautionary measures like new timing chain , spockets ,etc , and here I am waiting for the v8 m6's to become cheaper so I don't have to explain to everybody about the bearings is the reason why my cars are always idling for close on five minutes before I drive-off.
