Answer... according to my manualit's near the oil filter, on the back side of the engine. I haven't tried to replace it yet, but now you know where to look...

I just replaced the PCV valve on my 1987 CRX Si... It's very difficult to find, I had to stop by the Honda Dealer and get them to print out a parts location map for me.

The PVC Valve is connected to a black box located right above the oil filter. Thankfully you can reach it from the top of the engine.

Looking at your eninge from the top, you'll see the Programed Fuel Injection label on the top of your intake.

Directly in front of this label is a hose that decends down into the black box located above the oil filter. You'll probably need a flashlight to see it.

Disconnect this hose from the top your intake, then using a pair of pliers PULL the hose UP and OUT of the engine, your PCV Valve is connected to the bottem of this hose and will come up with this hose.

Now that you have the hose and PVC valve out of the engine, disconnect the old PVC from this hose and install your new PVC Valve.

Next, push the tube back into position on the black box it came out of located above the oil filter and using a LONG screwdriver, push the PVC valve back into it's hole until you feel it Sink into place.

Reconnect the top hose to your intake housing and your all done.
