B58 Bearing Material in Oil
Hi All
Back story first about my experience. Youtube DIYer and forum researcher. Prior car was a 2011 n55 335i (stg 2+ MHD, stg 2 XHP, Catted DP, Intake, Intercooler) that spun a rod bearing and developed a knock at 122k. I remember how much bearing material was in my oil along with shavings. Was not a fun time lol. Currently have a 2020 440i GC (F36) with about 35k on odometer. See attached PDF screenshot for maintenance and notes This is the second time I noticed bearing material in the oil drain pan. The first I chalked up to not having a new pan and maybe having residual debris in the catch pan. On the next oil change I purchased a new oil drain pan and there were no issues. Last oil change (the most recent) I found small bearing material in the oil catch pan but nothing in the oil filter. From what I read everyone recommends getting a Blackstone lab report which I shall and will upload the results after driving another 1-2k miles. There are no noticeable ticks, knocks or any weird noises to me especially after adding LM Ceratec. Only mod not listed that affects the engine is I have a BMS oil filter housing cap. My only thought with that is maybe the oil is not circulating properly due to a break in the bypass valve that has to be transferred over? Any thoughts/comments would be greatly appreciated. |
