Default vaccum and compression test for 97 honda civic ex dohc vtec.?

im buying a used honda civic ex and wanted to know where a good source of manifold intake is so i can run vacuum and compression tests on it to make sure the engine isn't crap. he only wants $3000 for it which is just below the bluebook. and it has 115,000 miles on it. can anybody help?

I am not familiar with this particular engine.

That being said, I would look for a vacuum fitting on the intake manifold itself. Possibly you may have to use the power brake booster fitting want a "direct connection" so to speak ....a source of vacuum that is constant and not involving any type of vacuum switching valves (like you might find on the EGR valve). Make sure you bring some hose adapters and some different diameter hoses. You may have to tap into a vacuum line that cannot be left unattached as it may cause the engine to run rough which case you'd have to "T" into the line.

Compression test ....make sure the engine is hot and prop open the throttle all the way. Best to take out all the plugs (check them for electrode color and condition while they're out) as it allows the starter to spin the engine easier (and do keep track of which cylinder they came from for your information and to do right by the owner in reinstalling them). Look for consistent readings across the cylinders ....if I remember correctly the gouge is the lowest cylinder should be no less than 75% of the highest.
