I am going to do some deferred maintenance tomorrow, to try to fix a few oil leaks, some potential problems, and keep the car in good shape and on the road. I have the following:
1. All of the power steering hoses (leaking)
2. GAS DISA valve repair kit
3. OFHG and VANOS oil line (leaking)
4. Synthetic fluid for front differential
I have some time off work and can let the car sit in the air for a few days, which is nice. My plan for this week is:
1. Remove belly pan
2. Replace front diff fluid and check for leaks (I have never had the pan off before)
3. Do the PS lines and refill (Top Tec 1200 ATF). I did make sure to buy the tool to remove the PS lines.
4. Do the oil line, OFHG, and change the oil. Check for other oil leaks
5. Take off the intake manifold to repair the DISA valve
6. Inspect and clean any sludge out of all the vacuum lines.
7. Clean the belly pan and reinstall
I have never had the belly pan off since I bought the car in 2016, so I expect to spend some time under there and find some other things that need addressing. I replaced the CCV with a cold-weather version in 2017 but I drive a lot of short trips in cold weather, so I know there will be some accumulation.
This thread was very helpful (thanks cn90!):

I'd be grateful if anyone has any advice for this job -- anything else I should do while I am in there -- or anything I should be wary of while I do all of this. Any and all advice is appreciated. This forum has provided a wealth of knowledge for me, and I am very grateful. My car is a 2003 3.0i with manual transmission and almost 120k miles, by the way.
