So recently I was told that I need to replace the vtec solenoid O-ring on my 1997 Civic EX but I have no clue where it actually is. Can someone help me?
Thanks

Okay so I have found it but now my question is what exactly does it do? The book for the car is no help...

This solenoid allows oil pressure to flow into the valvetrain, activating an extra, higher performing set of cam lobes at a certain, pcm-determined rpm. Since they are exposed to engine oil pressure (at least on one side when it's off) they are prone to leak. There are at least three special rubber seals in there, make sure your Honda parts guy pays careful attention to the catalog. One has a screen molded into it. It's not hard to remove the solenoid and replace the seals. Clean the gasket recesses well with some brake cleaner, or other oil compatible solvent before you put it together.

You'll notice: the old gasket is hard and brittle like plastic, and
It's not just an o-ring, two of the gaskets are specially molded. The o-ring goes on the sensor with the green connector, and it's probably not the biggest source of the leak.

Thanks for helping me find it Very new owner of a 94 Accord. I have a check engine light and I'm better sure its the Vtec. I think its in "LIMP Mode". My new issue is WHERE IS THE ECU??? Is it was under the Passager seat??? And how do you short it and were is the Light that flashs. tryed youtube nothing there.

dont use any brake cleaner intake cleaner or anything like that on a rubber gasket it will swell up and you will have a worse leak than what you started with

Should be behind the passenger kick panel I think.

Easier take to Advance auto or Autozone and let them sacan it for free.

scan tools are for 96+ obd2a/b vehicles.

he will have to jump the service connector and count the cel flashes on the instrument cluster.

I forgot he has a 94, then there is a connector taped up over the ecu, use a paper clip and jump it, the cel should light up, then count the flashes.
