I can't really see what you're talking about in the picture. I suppose the black "circle" was drawn by you to show something? But if we're talking about a quality control deviation in a rod bearing, I think you're right on waiting and making contact with manufacturer. |

I would never take a file to a rod bearing. That could cause all kinds of problems. Regardless, if you can feel it with your finger, then I wouldn't install it. That's the BE criteria for rejecting shells as well. Some shells get past inspection and not noticed. BE will replace it at their expense. All they need are the numbers written on the trays to send matching shells of the same thickness. |

The above picture was simulated That's clear, i have removed the shell and take some pictures I can clearly feel it with my finger, before i apply a file you can feel a tip and a trough, after the file just a trough This is the pictures after, i don't take same before I have ordered another set from Truner MS, can i take one upper and one lower shells from this set for installing them or do you advise me to wait for the replacement shell? I would like not to wait too long to close the engine Tell me how could we do it? If you need HD pictures by email tell me if necessary |

Here are the numbers,
On top blue 080 Bottom red 020 I have a question about the BE ARP bolts BE-CRB50-S65 they are reusable, but how many times? Are there a number of disassembly/reassembly/clamping after which it is recommended to change them? or they are lifetime use? |

Many people don't do that, but they reuse them anyway. You won't see many cases of that in an S65 engine community, but there are many chevy LS engine and Honda engine owners who do. I have a friend that lost a Honda k24 engine due to an ARP 2000 bolt (that's the same spec of the BE ARP bolt) breaking down. And he was not the first owner of that bolt, so he doesn't know how many times it was torqued, or what it's been through. Anyway, if you don't overtorque the bolts I assume you will be fine in reusing them forever. Hope you don't need to ever open that engine sump again though. I did reuse my bolts three times and no problems with that. And the last time I changed my bearings, I put in brand new bolts (together with be bearings) because I really believe that was the last time I opened up that engine. |

I torque them like BE said 50ft.lbs (68Nm) with (a good) calibrated troque wrench |

Hi all. Longtime Lurker. Posted since I just did my rod bearings.
Original owner 2011 E90 MT. 95000 miles. Oil changes usually every 7-8000 miles. Car has been relatively trouble free. I have done the throttle actuators and an ignition coil in the last year but otherwise the car hasn't given me any real headaches up until then. I always make sure it's warmed up before going over 3k rpm. I bought the replacement kit from lang racing and had my local shop do the work. Mechanic said they didn't look tooo bad but I'd like to hear from the pros, since this shop doesn't do a lot of these. Got the car back and alignment is off so they need to address that |

Also I SWEAR there is now a mild low frequency vibration sometimes at idle. I've had this car for 12 years so my butt dino is pretty tuned in with it. I did do the motor mounts as well. Could it be anything else? no CELs or weird idling. (I have had the fuel breather valve replaced within the last year as well).

The colour of your shell photos is really off here, and makes it hard to see how bad they actually are. Can you take any more photos to correct that?

Skip to ~30:40 to see the big end caps being removed.
Is it just me? Or do those rod bearings look like the OEM tin/alu/copper ones? [edit] Yes, I can see the numbers 702 at 31:33 on the top left bearing. Btw, he said it's done 145k miles, rod bearings (VPC) done at 82k. I'm amazed the crank broke in 1/2! Must've been going at full throttle at high revs to do that??

Ah yea, good point.
Btw, I've just re-realised how many more tin/alu/copper bearing engines mains have failed vs the lead/copper ones! (in our 'blown engines' thread anyway).

Yes, within that thread, and that section, I'm just counting failed mains, it's blind to RB type.
