Anyway, i know and felt you had an angry feeling about the Octane and i think that sometimes the bearings are like a hard carrying load especially for a man like you that wants to find a solution for all of us !
Therefore i can only have enormous respect and this for a man like you ! And that's why i wanted to say ...thank you man !
BTW...i asked you this yesterday and think you have missed it... about the video on this page and what do you think about it ? >http://www.m3post.com/forums/showthr...9#post15529269

Very common noise, although it's VERY loud in that video. I'm still not sure what the cause of that is.

My experience:
- My car did this too, especially after it was sitting for a couple of days. Not anywhere as loud as in that video. If video = 100% volume, then mine was maybe 30%? Didn't happen all the time.
- Got BPM dev tune and I swear it happened even less frequently. This I cannot confirm and it could just be in my head
- Switched to M1 0W40. Almost never happens anymore. If it does, it's usually when it's been sitting for 2 weeks or so. And even then, the sound is maybe 5-10% that I'm not even concerned about it.

NOTE: I don't know if the thinner oil helped the issue or not, just my experience of the changes that happened.

P.S. 120 Euros for a tank of gas argh. I think the most I've ever paid around here was $55

Have you seen what it costs the liter price of 98 Ron in this damn country ?

W///....exactly ! Like i said in the other thread (link to) when sitting for 10-15 days it's the clunk noise and about 25/30 % of the volume of the video just like your's ! ( but with louder clunk noise after hibernation in winter)
You know the ///M is not my daily driver ,and when i drive here like last friday...a trip to Brussels about 150 Miles, the clunk noise is gone !
Also the next day the car runs much better and feels stronger after a longer trip , that's why i said this car...the S65 engine needs to be driven and not playing the garage queen !
About the oil...i noticed after fresh oil change it's less, and again just like you but i'm using Castrol Edge 10W60 at my BMW dealer .
About the BPM dev tune..have it too,.same thing as you less noise,less frequently!
But one thing i'm afraid for it's the post of member M3PO,so here a copy of what he said about the video .>>>.That sounds very similar (but worse) to the sound that I had. BMW replaced one of the VANOS units and the sound is gone.
So when it's the VANOS i'm saying.....damn !!!
About the gas price...last year in summer i drove through the Belgian Ardennes very nice turns and roads through the forests !
Well that day i filled her up twice , i had to... knowing an ///M, and that day it was the price you said.... 120 Euros X 2 !
And had the impression that it was gold coming out of the filling pump...ohhh god man what a damn country ! And that evening on top of it... a restaurant with my wive ,my wallet was bleeding ! And when i see you'r price ...$ 55 ....well i said it already on this forum...and will say it again....God Bless America !!!

Now that my noise is almost gone, I'm really not too scared to be honest. Funny thing is, the reason I got an M3 in the first place was after I was in Munich for business trip for about 6 months. Realizing that I live where gas is about the cheapest in the USA, I had to experience owning an M3 in case I had to move back to Europe. Very glad I did.

Btw, I lived in Brussels when I was a kid. I'd love to revisit one day! Been to the Ardennes many times with my classmates.

I'm from Russia, tell me, how do I prevent damage to the motor avtoobil 2007. Maybe we should replace the crankshaft, or need to change the engine block?

You are full of BS!
Did you take this pic when prices were at its highest to have a bad memory? This is not the current price of 98 Ron in Belgium!

S65 Gurus...

When replacing the bearings from underneath the car, will I have room to use a stretch gauge on the rod bolts or will I be limited to simply torque settings?

I plan to run ARP.

Thanks in advance

ARP bolts are straight torque, not stretch. 50 ft/lbs I believe.

Thanks RG.

Here is what the info from ARP says:

Part Number: 201-6001
Application: BMW 4.0L (S65) V8
Cap Screw without Washer - Rod Bolt Installation

[1] Please check the part-number(s) for your application
against the part-number(s) listed on the instruction sheet.

[2] Make sure there is an adequate chamfer around the bolt
hole on the connecting rod cap to clear the radius under
the head of the bolt.

[3] Use ARP Ultra-Torque Fastener Assembly Lubricant
to lubricate the threads of the bolt and the under head of
the bolt. Then install the bolts and tighten them hand
tight.

[4] ARP recommends using the STRETCH METHOD when
tightening rod bolts. Following the instructions for using a
stretch gauge, Stretch the bolts to . 0075 - . 0080 .

[5] If you do not have a stretch gauge, torque the bolts to
_ 60 ft-lbs using ARP Ultra-Torque Fastener
Assembly Lubricant.

[6] The connecting rods should always be re-sized after new
rod bolts are installed.

[7] A log should be kept on the original non-torqued length
of each bolt. Bolts that have any permanent deformation
or have increased in non-torqued length by more than
.001 in. should be replaced.

[Cidle]

ARP-RBS-S65 specific: Stretch to .0065 - .0070 or torque to 45 ft-lbs with ARP Ultra Torque Fastener Assembly Lubricant.

ARP Kit #: 201-6001 specific: ARP recommends using the STRETCH METHOD when
tightening rod bolts. Following the instructions for using a
stretch gauge, Stretch the bolts to . 0075 - . 0080 .
[5] If you do not have a stretch gauge, torque the bolts to
_ 60 ft-lbs using ARP Ultra-Torque Fastener
Assembly Lubricant.

Notes:

• Calico coated bearings start life as 702/703 factory BMW bearings. An anti-friction coating is applied on top of the bearing surface.
• Top table are virgin 702/703 bearings as measured in the "Official Bearing Wiki" Thread.
• Bottom table are a full set of Calico bearings with approximately 16k miles on them.
• Virgin 702/703 bearings have thicker upper (red), and thinner lower (blue) bearings.
• Calico bearings have thinner upper and thicker lower bearings (opposite of OEM).
• Assuming bearings were swapped, the average thickness of the Calico coated bearings is 0.00010 inch thicker PER SHELL than OEM.

Interesting new news found on the S85 M5 side of things, bmw started using 702/703 bearings in MY2009 M5's and continued on MY2010 cars.. Six 2009 s85 m5 engines that were opened up by Troy Jeup on M5board had 702/703 bearings. Those around late-mid 2008 built cars started getting these newer bearings.

This is what he told me:

"The 702/703 bearings all looked great by the way. Highest mileage as 42k and it looked far better than the 088/089 bearings with" -Troy Jeup
