Address first the engine problems (overhaul) and kalampag before moving onto the body/paint.
Engine:
- get a compression test first to determine what type of overhaul it'll need (change piston rings or just he seals, etc).
- do a general service na rin (change all the fluids, filters, etc)
- buy the needed parts on your own if you have the time... canvass in Banawe. I saved a lot by doing this before when our '99 AE111 LE needed an overhaul.
Doing a hands-on approach to fixing up your car will let you learn most about it.
