Probably a very unpopular opinion here, but... food for thought:
If the engine and bearings have lasted this long, what are the chances that the bearings should not be replaced at all, since the entire mechanical system has worn uniformly over the course of 170k miles? I would be afraid to crack open an engine wih that many miles, and return just one assembly to factory clearances. It seems like youve gotten a golden egg of an s65. What are the chances that tampering with whatever miraculous assembly quality/combination youve inherited is actually going to be a detriment to the longevity of this particular build? Thoughts? |

I would do what the OP is doing. Change the rod bearings as preventative maintenance and keep driving. Consider a rebuild at 250k miles if a compression leak down test warrants it.
If you want to be a worrier or want to throw money at the motor or are a curious and skilled DIYer, consider refreshing the main bearings at some point along the way since they seem to be the next weak link. |

I was going to go with stock bearings for that reason.. But 95% of the people in here recommended BE. Along with the place doing the bearings. The car is at the shop now.. They Quoted 18hrs .. lol So the car will probably be done tomorrow, or Friday. |

It goes against industry standards and known facts. Manufacture's guidance on bearing wear and causes. The risk of not changing the bearings and something going wrong is greater than the risk of changing them and something going wrong.

Paying a shop 18hrs to do bearings is just as stupid as considering stock bearings.

You are getting ripped off at 18 hours. I would have taken it somewhere else — like a shop that has done them before and charges a flat rate. Here is a post from a shop in CA with a few pricing options that gives you an idea what this job should cost:

I know they are bending me over. Another shop I called was the same price.
3D Autoworks in hudson NH was $1000 cheaper. But they wanted to do compression test, and leak down test before hand. (And they originally told me they won’t do them since the miles are to high) Just want them to get done. . I’ll save some $ by doing the plugs, coils, and vcg myself. |

It's not even close to 18hrs. My mech took about 7 hrs with me asking a million questions and taking our time. An experienced shop should take no longer than 8-9 hours.

If original rod bearings made to 170K, I would've leave it alone. Probably they are good for another 170K. If original owner was a forum member it was his 4th bearing. Mine has 84K miles daily drive. I really drive the car hard and no plan for RB replacement. Oil change every 6-8K miles when I have time. Having an accident and totaling the car has more chance than RB failure..
