Bought a 1997 Civic DX manual. It has 119K miles on it.

How do I replace the PCV valve? and How do I replace the Multi-V Belt?

a little background story.
I don't know much about the internal parts about cars.
Bought a used civic that's drive-able.
Went to Autozone and ask a worker, who also owns a civic, for parts I should buy so it can run good as stock. some of the things he recommended me are the PCV valve and a V-belt.

 

The PCV valve is most easily accessed from below the car. It's above the oil filter and plugs into the breather box.

You have three separate drive belts -- power steering, A/C, and alternator.

When you buy a used Civic, do an ignition system tune up and change the engine oil.

 

yeah I already changed the oil and spark plugs and the wires.
Someone looked at my car and it looks like I'm gonna change my hoses later.
I have no power steering because it's the DX manual model.

Thanks for the PCV advice, didn't do it today but will tomorrow.
