Final engine assembly was completed and after some extensive diagnostic work on an intermittent cylinder 5 misfire the engine has been running great. 1200 mile break in service has been done and I’ve been having an absolutely blast with the car.
Haven’t driven either of my m3’s aside from one needing state inspection since this June. The clutch has been the most different from anything I’ve driven as far as pressure required, grab point and grip. But besides the lack of cup holders it’s now the choice of vehicle of my wife Hope you all enjoy the final photos and thanks for the comments. *The cylinder 5 misfire was one of two cam followers popping off the lifter due to a weak spring retainer. So due to the Valvetronic spring tool not fitting between the frame rail and cylinder head the engine came back out for a 5 minute repair. |

Is there a certain oil temp range that helps get rid fuel in the oil? I've heard short drives can cause water condensation to build up and if the oil temp doesn't get past 100C/212F then it never evaporates, but how does this work if there's fuel in the oil as well? |

I don't see how contaminated oil would cause the engine to burn oil but I'm not a professional here - maybe someone else might have an answer for that. |

I plan on doing my rod bearings myself, been dealing with bmw’s for about 12 years, first time doing a job dealing with the internals of the engine. I’m mechanically inclined, how ever my question is will i have to remove the oil pump to access the bottom end to remove the bearings, if so what replacement hardware will i need to complete this job. Also if anyone have a complete list of replacement bolts for the oil pan, that would help me out tremendously, i also plan on making a post and uploading pics of the job.

Hit up the folks at 5150autsport as they can help you with rebuild parts etc. If you can afford the time and expense either rebuild your oil pump or just buy a new one. Check out this fellow Floridan's recent work on his M5's ro bearings. He had some other stuff he did along the way. He is a good presenter but the content should not be used as a how to. https://www.youtube.com/@Yes_Way_Jose/videos

JayDD007 Now that you've completed this project and what you've learned - how many labor hours would you estimate if you had the same repair on another m5? |

There is a mechanical chain tensioner that needs to be removed to slacken the chain before removal, then 3 bolts to remove the pump. Your local parts department will have the list of the “in conjunction with” parts. If you don’t plan on going through them I can provide them for you, it’s just quite a large list of bolts and gaskets. |

I agree with you I really think that’s what does it people don’t realize they’re getting fuel and condensation in there oil reducing it’s effectiveness when not fully warming it up on a longer drive and i bet that’s what has destroyed many of these engines.
