Lost pin when removing camshaft/valves. I've looked through both the Haynes and Chilton repair manuals, and online and I can't seem to find where this goes. My head gasket blew a couple months ago, so I took it apart. Then work got in the way and I just got back to putting it all back together. I cant seem to find where this goes. Any help would be appreciated, I wouldn't make a post unless it was my last resort. Thanks!

Where does this go?

 

What year and trim accord is this from?

That looks like a control valve where pushing that valve with oil pressure will expose or shut off that hole. Like something for the vtec system.

 

Thanks for the reply; sorry about the late one, Work again. You were exactly right. It was the plunger for the vtec solenoid, it goes right in the middle. It doesn't have a spacer, so I had trouble matching it up in the Haynes.

 

By the way it was a 1998 accord lx 2.3l 4 banger
