With copper low, that means you are probably just wearing down the top lead layer of the bearing.
I would say no need to be alarmed, but it shows your bearings are wearing and imo I would be planning to do a rod bearing change in the future. In terms of how long you have, no one can know for sure, a bearing could starve for oil for a couple of seconds, then spin the bearing causing rod knock or shoot a rod out of the block depending on how bad it is. or it can continue to run fine for another 50-100k assuming the wear doesn't continue at the same rate, if it does continue at the same rate then you probably have much less time.

Yeah, I have been reading about the issue and I have a hard time believing that BMW didn't know how to properly clearance an engine they designed. Last I looked crankshaft based engines have been around for quite sometime.. So do we really understand the root cause of these seemingly random rod bearing issues?

Here is what I would do. Take it to a shop that accepts the warranty company and also has experience with the S65 bearings. Assuming they agree that the issue could be bearings, they will then tell you what the charge is to inpsect the bearings. Ask the warranty company to pay for that. They likely won't but it won't hurt to ask. Once the bearings have been removed, if they are worn, you might stand a chance of having the warranty company cover the parts and labor to install the new bearings.

Instructions specifically says not to collect oil from oil filter for obvious reasons. The filter catches all the junk and anything you collect from the canister might throw off inaccurate numbers.

First thing to do is delete this thread.
Then you say you heard a slapping noise at times and you paid the shop to inspect. They found bad bearing wear. Then call insurance with the findings and see if they'll cover it. It's worked for others. Last edited by aus; 09-28-2017 at 07:03 PM.. |

You can collect from the housing. What they're saying is not to just let oil drip off the filter into a collection container. I have taken samples from the filter housing and there were no weird spikes or contaminants. My suggestion would be to drive the car as you normally would for 20-30 minutes to make sure everything gets nice and hot, then shut off the car and IMMEDIATELY take the sample from the filter housing before it runs back down into the sump. I have done this exact procedure before on my M3 and two Audis.

Haven't heard of any failures yet with these replacements. However, was told that several motors with the recommended BE bearings setup were subsequently used for some serious track time, had the bearings pulled again later for inspection, and did not appear to show any concerning wear

I got my bearings replaced by my non BMW... 0 deductible national warranty....got a check engine light and turned out had 1 bad vanos solenoid ( this is what i was told by the shop ) so... the shop i went to apparently convinced the warranty adjuster bearing "shavings" caused the vanos to go bad. there for we need NEW BEARINGS!!!
IMO my bearings look just fine for a 31k 2013 s65 motor. Also... i did have to pay out of pocket for bolts ( and a LONG list of other things ) since we used arp and not OEM. Had we used OEM bolts, the warranty would have paid, so i was told. Last edited by 65fastback; 09-28-2017 at 10:01 PM.. |

JUST to be clear.... i did not ask for any of this! i came in for a check engine light and was told later on that day i needed new bearings since i had 1 bad vanos solenoid due to bearing shavings.
moral of the story here is... be carful what you wish for! |

I had a ppi on my car (08 w/77K miles), and the mechanic said he saw "flecks of metal in the oil filter." It didn't occur to me that this was not the ideal way to make the analysis, for the reasons stated above. The dealer and I agreed that I would supply the parts and that he would pay the labor to his friend's indy shop. The indy was a BMW certified tech, so I went with that. The bearings looked fine once he got them out.
To me, paying part of the cost of having it done before I even took delivery was far better than the aggravation of a bearing failure or the worry every time I hit the throttle. I agree with those who say the warranty company would never agree to a pre-emptive repair. They aren't interested in helping you; their only interest is in hanging on to their pennies as long as they possibly can. Terry |
