We're you using a breaker bar to turn the engine over ? I'd imagine it takes more than a regular 3/8s to turn it over but I don't know as I've never done it. I think Mighty Mouse who posted in here before works at bmw or used to and maybe he could chime in. When your engine died did you hear anything unusual like clanks or bangs coming from under the hood or did it just sputter and die off? Also no need to thank me, thank the others on this forum who are ridiculously knowledgeable and have shared so much info and time. |

I reread the pics you posted about the work done, and the last page said discovered that previous shop had found an internal fault caused by outside influence. New engine replacement quote was provided. Or something along those lines. That went from 0-100 really quick, I'm guessing the Indy knew the engine was on its way out and there was a serious problem if they're providing a quote for a new one. If you have the time and care to, why not contact the Indy shop and see if they can tell you what was catastrophically wrong with the current engine. Luckily there's plenty of used n52 and n51 engines and they're fairly cheap so if you need a new one and you have the tools and know how, you can swap one in for maybe 1500$. I think there will be some obstacles if using an n52 donner though. What'd you get the car for If you don't mind me asking? |

Do you have a borescope to see inside the cylinders?
I'm not sure if you could even see anything since you can't turn the motor over but you never know. I think you can get a decent / cheap one on Amazon that connects to your phone Can you remove the oil filter to see if there's excessive amounts of metal bits? Or lift the car and drain the oil? I don't how much it will help with diagnosing the problem but if you can't turn the engine over at all, something may have catastrophically failed. |

I googled timing chain guide and n52 just out of curiosity because I've never read any posts about it for our cars, apparently on the n5x cars there are very few issues. I would think maybe a botched timing chain guide replacement is the reason before the VC, but I don't know. How many miles are on your car? Also when the engine died did you hear any noises from the engine area? Or it just shut off? |

aprox 93k. no noises just "depowered". before the valve cover was installed there was no check engine light and after the valve cover was installed check engine light came on. they reported metal shaving in the oil which i wasnt able to check because i bought the car and instantly took it to bmw to get sulev work |

Does your oil filter housing have a leak? Either the engine was starved of oil and seized or it's a timing issue and you have major piston to valve contact. Would recommend draining oil or dropping the oil pan look for metal bits or shiny gold bearing material

The service report shows it was fixed, is it possible there could be valve on piston contact and you wouldn't hear it in the cabin? I don't trust the oil level sensor very much but haven't seen or read much about them failing. If it is oil starved, and the sensor had failed, would sensors not go off about the engine over heating? Or you wouldn't know until it's too late? Sincere question as I really have no idea. |

when i bought the car it was misfiring and i was still too new to inpa and didnt have ista so i only knew it was misfiring. i guess the owner before me had an indy shop put a valve cover on the car. when i drove the car i never heard anything or concern. def wish these had a temp gauge on them |
