^ Blue smoke is oil burning. Grey/black smoke is fuel. White is coolant (steam/water).
To the OP: Not sure where you can get all the stuff you need to do the leakdown. If you don't already have an air compressor, I'd just take it to a shop and have them do it (unless you're just looking for an excuse to buy a compressor).
You might search in the UTH forums or UTH: Technical. There may be a thread about leakdown testing with details for everything you'll need. Most of it is probably available online.

it is not a h22. its a b21.
It's done. Don't drop any more $$$ in it to fix it. Any engine repair will well exceed the car's resale value.
I can just about guarantee blue smoke isn't the only issue the car has. Kinda like rearranging the deck chairs on the Titanic... Sure you did it, but the ship has already sunk.

Don't listen to the Poop Magnet (or should that be Poop Magnate?). 
You can't put a price on sentimental value. 
Worst case scenario, it's time for an engine swap. Time to figure out what'll swap into a 3rd Gen.
Sure, it may cost more than the car's resale value to fix this issue, but that doesn't mean that you should ditch it. You'd probably spend even more money if you have to buy a different a car to replace it, and it probably wouldn't be nearly as fun to drive as the Prelude.

I thought the crankcase vent valve could cause oil burn if the valve is dead. PCV valve? Otherwise, the blowby is pressurizing the crankcase and forcing the oil out past the the good vent valve and into the intake.
The pressures on my 92 Prelude's (4th gen) H23 are 160ish, 120, 160ish, and 160ish. So your pressures look great by comparison. The #2 has been low for the last 60k miles but it runs fine (26mpg).

No Honda that starts with the Letter "P" Is worth dumping $$ into. 16 year old Prelude (at it's newest) will be a large hole you toss $$ into never to see again.
Drive it until it stops moving under it's own power. Add Oil and Gas when needed. Then call the big hook to take it away, so it can assume it's position on the circle of life for recycled steel. Next stop, razor blades.
