I also found a weird plastic thing inside the oil pan. What do you think it could be? It doesn't look broken off if inspected closely, just looks like a very small cap:
So, some info on the car and it's maintenance: E91 335i with N55, first registration at 06.2010, currently at 188.000 km. Full service history at BMW with their more lengthy service interval. The exact oil changes were as such:
1: 06.2012 - 24.500 km
2: 05.2014 - 44.150 km
3: 06.2015 - 69.500 km
4: 05.2016 - 95.800 km
5: 07.2017 - 124.800 km
6: 05.2018 - 140.000 km
7: 05.2019 - 164.000 km
8: 10.2021 - 176.000 km (first oil change done by myself when I bought it)
9: 07.2022 - 188.000 km - rod bearings service
Here is how they look:
What is your take on the state of the bearings given the age and maintenance of the vehicle?
Just to add, I opted for the King bearings. My crankshaft had rrrrrr labeled on it, so full red OE bearings. Tested all clearances with plastigauge and they were just a little over 0.038 and clearly under 0.050. I would have estimated around 0.040 - 0.042. The repair manual stated that they must be under 0.045 for my car. I was surprised just how consistent they were, across all 6 cylinders.
Drove the car around 700 km's since and it drives perfect, so I didn't kill the engine by doing something wrong. Need to check if my new oil pan gasket leaks like the old one.
EDIT: The pictures are not showing, I don't know why. I created an album here: https://ibb.co/album/3y1nP9 |
The plastic thingy you found is from the VGC, pertaining to the PCV system, I suspect the VCG was done before and the whole plastic stuff broke off...
