Nice DIY Chris. Here in Holland, they say the S54 engines need new rod bearings every 60k miles. Have a great weekend, Dutch regards, Nico.
Great video, I’m going to be doing this on mine soon 👌
Awesome video
oil has to warm up: flow means pressure, to separate bearings from the crank.
WD40 will remove that plastigauge very easily. I wish I dropped my subframe on my 335i like you did on this S54 when I changed my rod bearings - #1 upper and lower were broken in half when I got in there. I was wondering why the engine was rattling for a few months - live and learn. Great content either way bro! Also too bad on that oil pump bolt - I would have replaced it while I was in there but you could get to that bearing without moving it so no harm no foul! ;^)
How many miles on your N54? About to do my bearings this month, wondering what mine will look like... Thanks for watching and leaving a comment btw, Cj!
@@TheBimmerBarn 117.8k. Runs like a dream at least for now. Wind noise is a bit up as it is a e93. I never liked BMWs but this was a good deal and your vids really helped me out with the basic maintenance on her.
I see you had a quickjack. I will be doing mine soon on a quickjack. Did you support the steering rack with anything or just let it hang?
I just let it hand with the rest, and make sure you remove the lines before letting it hang, so it doesn't stretch the rubber hoses. Quickjacks are a life saver. Thanks for watching!
