Im going on a 10,000-12,000km trip in 3-4 months time with a 2001 Civic dx 1.7L with a MT and I am looking for advice on what I need to do to my car to make sure that It will not break down on me. I am not new to maintaining vehicles and here is what I have done so far. When I picked up the car 2 months ago I used the tried and true assumption that if I didnt find a receipt in the car then it had not been done. The car has 300,000km on it already.

Changed oil twice 5w20 mobile 1 synthetic.
Changed air intake/filter for a short ram intake.
Changed spark plugs.
Changed both oxygen sensors.
Changed cabin air filters
New front rotors/pads
New rear drums/pads
New wheels (14" enkei alloy)
New tires (snow w/studs)
New Windshield
New wipers
Cleaned throttle body
Replaced Valve cover seals
Replaced cam seal
Adjusted valve gap to factory specs.
Changed MT fluid
Full exhaust OEM honda
Lower ball joints
Wheel bearings front changed / checked back they were fine.
Coolant flush.
Fuel injector flush with Seafoam (vacuum line)
Engine oil cleaning with Seafoam

To do.
Timing belt, auxilary belts, water pump.

Im looking for any other suggestions on things that may need to be done and/or are common issues with these cars that I can look into, to make sure that it doesnt break down and if It does I will be able to fix it easily on the side of the road.
