I'm really impressed with your ability to fix these various things on your car.
I was happy just to learn how to change the oil and filter on my Prius.
Before receiving this car as a gift on June 3, 2017, I knew enough to change oil and replace brake pads on a '90 accord, and the brake pads info I got out of a Chilton manual. My dad had bought me a big socket set from Canadian Tire when it was 75% off (aka- paid close to what it was worth.) And I stole his used torque wrenches. (Well, borrowed, but... yeah.)
Then, I discovered the magic of my local library, and it's free subscription to AllData. Punched in my VIN, and they gave me the entire
technician's manual for every possible thing I could need to do to my car.
Cross referenced the repairs described against YouTube for that practical, down-home touch.
Discovered that the dewey decimal code for auto repair is 629.24.
Read three chapters in a book called 'Automotive Fundamentals' from the year 2000 (fresh info for the age of my car!) and can now tell you the difference between a crankshaft, camshaft, and a half-shaft, as well as an in-depth discourse on why the bits of the engine are there, and where to expect them in almost any car (45-ish pages?).
If I do my own work on the car, assuming I'm literally 1/4 the speed of a professional technician, I still will be paid $34 an hour, and I'll have that incredibly satisfying feeling about knowing
exactly where my car is at, from a maintenance perspective.
Like MMM says- Just think to yourself "Many people have done this in the past. Many people will continue to do this in the future. Many of them have
none of the advantages that I have right now.
