My car has been inoperable since march.
It is currently at 98,550 miles.

One of an engine components failed, but I was not completely sure what... I had to research it and for the past 3 months been trying to ensure and narrow down the issue, AND plan for all the laundry list of things I could do at the same time, since I have been pretty much stuck home since April.
Finally a couple of weeks ago, I decided to dive it, order all the necessary replacement parts and took my car apart.

Here is the laundry list of things I was able to accomplish and just finished putting everything back together as of last night...
1) Eccentric Shaft Actuator/Motor for the variable valve timing system.
2) Replaced the seals and gaskets on the High Pressure Fuel Injectors.
3) Verified conditions of all the spark plugs. (#4 was soaked with unburned fuel, while the rest were dry).
4) cleaned the engine bay and engine to remove all oil and gunk accumulated, so that I can more easily detect any leaks right away.
5) clean all the air intake valves and the whole air intake system (air intake manifold, throttle, replaced all the necessary seals and gaskets, cold side charge pipe, intercooler)

6) added an Oil Catch Can
7) cleaned the engine header and valve cover, and replaced all the seals and gaskets.
8) Replaced the air filter
9) order 4 new crossed drilled and slotted brake rotors/docs, but they won't be available until September
10) was going to drain and replace the engine water cooling system, but the lifetime coolant seems still clean and working, so despite having ordered new BmW blue stuff coolant, distilled water, thermostat, I have not replaced any of it, saving all my available spare parts for when the system fails.
11) bought replacement TPMS
12) just got brand new tires Delinte D7 all around.
13) Fixed my driver's door external handle.
14) I think I have forgotten a few more things... It is getting late now, I will add to the list editing later when I remember to go back to my notes.
