Full disclosure, I recently posted about my experience running RP for 1000m on my n55 but I am certainly not shilling. I ran a very gentle OCI and changed filter at 500m and knew there was some risk. I think I'll try the ESP mentioned in that post soon (I had an apparently long failing PCV)
If it isn't clear, I am truly sorry that you had this outcome.
Edit to add: I read through your recent posts and saw YT shorts but have been wondering if you think your cooling failure shortly before this was relevant and if you have thoughts on why your filter looked crushed. |
the cooling failure happened as I puleld into my garage, the plastic hose above the radiator cracked and started spraying steam into my garage. I shut the car off immedietly and had a new METAL hose replacemnt from Amazon 2 days later. I really don't think it played a part I did not drive it like that. I shut down the car slammed the door shut and then it started. The oil filter definetly could be an issue but when asking others they said they have seen much worse. The filter cage was intact, I used the new o rings that came with the Mobil 1 filter and I've done this procedure a dozen times.
I don't even know if I'm going to bother with the oil pan drop. 6.5 hours of book time when I can drive down to the junk yard and for $1000 pickup a 75,000 miles N52 and use those hours to swap it in. I may just part out the car and buy something else. I'm not really upset the car cost me $6000 and lasted 5 years, cars depreciate more than that and I got 75,000 miles out of it in that time with minimal issues, had to replace my rear seat fuel tank pump housing which leaked like they all do eventually, and I put on a new water pump at 80,000 miles when I got the car and did reliability upgrades like the micky mouse flange and drain fill GM trans with filter change.
AI says BMW changed the bearing formula in 2010.5 from trimetal with lead to bimetal aluminum and people claim the lead bearings were superior but green policies forced the change. I cannot confirm this with RealOEM on different years all list the same bearing part number. It is a fact in N55 and S63 (?) and those bearings are trash. As far as I can tell all the N 3.0 engines use the same bearings so why would BMW switch to lead free in 2010.5 on only some models and not others.
I really can't expalin it other than the only deviation I've made in service was Castrol to Valvoline and MANN to Mobil 1 filter.
