Sounds like a shop stripped the rod by accident, altered its course of thinking and wanted to charge OP extra $$$ to rebuild the engine!

OP regardless of what the shop tells you, its simple, the car was under their care. If it was truly stripped they would have stopped. Not cleaned or went any further, started documenting and taking pics as any legit shop would. But somewhere between taking it off initially, reinstalling to check clearances with a plastigauge and calling you there is too many things missing that someone that isnt at fault would have ready to show. This isnt a service in for a light bulb scenario and you need to take off air filter to get access and notice the air filter is dirty so while youre there did you want to take care of this? Then yes youd be liable for the cost of the filter. The work you directly paid for to get done to the car was not done correctly and that isnt your fault. Let us know how it plays out. Edit: As a shop you are offering a service, if you cant or dont have the know how of doing the work you simply dont do it. In this case the shop took on the work and should be the ones to make you whole. But instead they're beating around the bush.

Out of curiosity, what are the too many things missing that you mention? I'm not saying they weren't missing...but I don't think any of us know what you mean without an explanation. Quote:

I did it in this order. (Example: One rod/cap at a time, to make sure I didn't accidently swap caps) I didnt see this posted. I visually inspected each bolt/bearing/cap (I find it hard to believe that the stripped bolt had 0 metal/thread on it that it wasnt till the re-use of that bolt, to varify spacing on the new bearings, that they noticed it was stripped. They are usually covered in oil. Something would be on the OE bolts) Some of the things going thru my head if I was going thru the steps to swap bearings that I thought was missing from the shop. OP mentioned by the time they told him the bolt has no metal. Even after the 2nd time going back in?? As to your other comment, yes, they are. This is something so precise that a pre-existing issue of a stripped rod bolt was the cause?? Come on. I would lawyer as soon as I heard that. If the shop worked on your car and then took it for a test drive to validate the issue is resolved and spins out into a curb because your tires are bald, would you pay or split the bill on the damages with the shop?

Either the mechanic at the current shop screwed up or a prior mechanic or owner who was replacing bearings screwed up, tried to hide the screw up by not actually replacing any bearings and putting the rod back together (and swapping back any new bearings replaced before the faulty work), and the owner sold the car to an unsuspecting buyer.
The OP has not provided any history on the car, but even if he did, the prior mechanic/owner theory would be hard to prove. |

^ for sure anything is possible. I just don't buy the latter. If someone messed up and stripped a con rod to the point where it won't torque down to spec, knowing what we know about S65 bearings, that car wouldn't have made it 500 or so miles like the OP said it had between purchase and current shop touching it.

Read the very first post carefully.
He said the shop claimed they couldn't achieve the torque, but that didn't even matter because the adjacent rod journal was out of round by 1.4mm, so he needed a new engine anyway. Ya right. Very, very smelly...

Just read this post, and agree something very smelly.
I build engines for a living as a QA tech (diesels, but same principles apply) and have seen hundreds if not thousands of stripped bolts. Absolutely ZERO chance that there would be no debris to be seen after pulling threads out of a rod, nor would a rod with only half the original threads be able to take the loads to drive 500 miles or even 5 miles. Not possible. I have seen enough ventilated blocks from rod issues. Rod bolts are the third strongest in the engine, but stretch style (OE BMW bolts) do tend to snap rather than pull threads. Also it is rather easy to "over torque" stretch bolts as once they begin to stretch the force required to turn them does not increase much at all. It is the elastic properties of those bolts that hold things together. But still, they generally snap prior to removing threads. My bet here the shop somehow damaged the threads, cleaned it all up and then made the call. There had to have been some debris as a result of the failed "20nm" attempt somewhere. If you could not get beyond that small level of torque then the bolt kept turning and as a result would have removed even more material from the threads. Yet none was to be seen when the OP came to the shop. That is pure BS right there. My heart goes out to OP in this case, but the shop should bear some level of responsibility for the damage. They have insurance to cover such things after all. I would have been on the phone with a lawyer right after visiting the shop. The retainer would be far cheaper than replacing the engine. |

Just going to say that you have to be advocating for the devil to defend the shop here.
It's wreaks of foul play. No way in hell is it prior damage. The story makes no sense. Let's say the shop is innocent, forsake of argument, they should cover this on goodwill given how it seems suspicious as hell. If they intend to stay in business... |
