I read on a post somewhere about "why is my oil always dirty straight after a service" regarding these BMW engines. Well that is because when you drain the oil out the drain bung, the sump still catches about 1 litre of dirty oil!! The drain bung is not at the bottom, it is a very poor design. So after you change the oil with fresh oil, your still running about about 20% dirty grim oil 🤐
Approximately 25 man hours into doing this job and its not fully put back together!
All 3 chains, guides and tensioners are on, flywheel, clutch, gearbox is back in, driveshafts, mounts and heavy stuff is back together.
Just need to build up all the small stuff up top, like EGR, EGR cooler, throttle body, injectors, vac pipes, wiring harness, covers etc etc. Then fill with engine oil and gearbox oil.
I'd say about another 5 hours to go into yet before the first start up.
And for the record, I would never do this job again, even for a ridiculous amount of money.
