Good advice has already been posted. There's one thing I will add. The F-series motor will, on occasion push out the balance shaft seal and you will lose the contents of the oil pan in short order. The aftermarket makes a seal retainer that is something like $8. Get it, and install it.
I can't remember what I did to put the one on the wife's car when we went through that. I don't recall it being as invasive as that TSB is spelling out, but it's been a few years since. As I recall, you just need to pull the cover back enough to slip it in there. Dorman actually makes a part that (surprise) works just as well as the OEM Honda part.
FWIW, my wife drove hers almost 15 miles, in the summer, in Georgia, with the oil light on after pushing that seal out. It glittered up the pan a ton, but after a few short oil changes, the car was back in service. Sheer luck? Maybe, but the car was running fine 4 months later when it was rear-ended by a box van and totalled.
Also, the symptoms that
@eljefino posted are spot on, you can also listen for a rattling noise in park that is the symptom of one of the internal bearings slowly dying.
Ok, third thing. If you do get it, check the heater hose that runs underneath the distributor. Oil likes to leak right there on to the hose and it will eventually weaken and fail.
Other than the salt car issue, if you find a good one not rusted to pieces by now, it should be a good deal.
