Overview of the Situation I'm In:
Recently my 2000 Camry w/ ~286,300 miles (5S-FE) started misfiring on cylinder #1, with oil intrusion on the same cylinder, a nasty fuel smell, and poor compression across all cylinders. Haven't concluded the exact issue yet; shop I usually go to said it’s the motor (block/pistons), someone in another thread said it might just be that the mechanical timing’s off (timing belt’s only a couple years old so I doubt this), and I also had the thought that maybe it’s the head gasket (but that’s also only a few years old, so again I doubt that’s the issue). Was a light oil burner for years, practically ran dry on oil at least once, I accidentally drove it overheated for like 10-20mi a year & a half ago (which reportedly did not cause damage; regardless, I need to learn to check my temp gauge!), and for a few months prior to misfiring, I would often (but not always) get a non-steady idle, which went away once the HVAC fan was turned on.
Been occasionally turning the engine on for short tests, but the last time it sounded even weaker than before; had to hold the gas just to start it.
Needless to say, even though I’m planning to a have a more specialized shop look at it for proper diagnosis, I figure it probably is the piston rings, and that the engine’s toast as-is.
My Question:
If that’s the case, what would be my best option out of these? I want to have a worst-case decision ready ahead of inspection, so work can begin immediately if possible/necessary.
All that laid out, you can probably tell I’m leaning towards keeping the car, but I threw in “full replace” in case y’all think I need a reality check.
TL;DR
Piston rings may be bad.
Wanna prepare a worst-case solution before thorough inspection.
Options:
1) Swap – Was told to avoid this
2) Rebuild – Preferred option
3) Factory new short block? – Also preferred if this is even real
4) Replace vehicle – Would rather not
So, all that said, I’m curious what you other “classic” Toyota owners think is best in this situation.

- Swap from lower-mileage car.
Mechanic I usually go to advised against this, as you don’t entirely know the quality of the motor you’re getting, and there’s (basically) no warranty. Don’t have much of my own thoughts on this one, other than I’d assume it’s the cheapest solution? - Rebuild the current engine.
Probably the option I’ll go with, as it’ll probably be the most feasible and peace-of-mind way to keep the car. Not sure what auto/machine shops in the Orlando area will do that for a 5S-FE though. - Factory new short block?
Don’t even know if this can actually be done. I saw this site, which seems to act like you can just buy a freshly made short block? I kinda doubt that’s actually what it’s about, because why on earth would Toyota still be making those after 25 years? - Replace the vehicle.
This would solve a lot of other problems: the hood paint looks like crap, the front passenger fender’s dented (and a little rusty in that spot), grille’s busted, front bumper has a fist-sized hole, rear windows need the motors & runners replaced, steering wheel is losing the soft padding material, sound system needs a redo, rear bumper could use some paint too...
However, we’ve had my current Camry for 18 years; I practically grew up with that car. It also means we have a long and well-document service history. Transmission was only replaced a few years ago. Most of the issues are cosmetic, so I could just fix them myself, and even if I don’t, then if it wrecks I’m not losing a pristine-condition car. It’s also a 90s/early 00s car, and I really don’t want to drive something much newer than that.
