I did a search and cant find the thread that has a scan of a vtec head(b16a or b18c1?) that specifically points out that "PIN." The Pin is under the middle cam holder. When you unbolt it and take off the cam holder, it is visible. I just need to know what it looks like. I dont know if its missing or not. Or if anyone has info on how much it will cost with the washer. thanks in advance

 

Ok, are you referring to the rocker arm shaft? Or the vtec pistons that is in the rocker arms?

If you`re referring to the vtec piston on the rocker arms and not the shaft -- It's basically a pin that is inside the middle (vtec) rocker arm. You will see it in there.

::Trying to get picture::

 

Here is the pic:



If you look at the arrow at the bottom right pointing towards the black hole to the left, that is where the vtec piston goes. Just below the VTEC camshaft where the rocker arm is on, is the rocker arm shaft.

HUmmm. what you are discribing sounds more like the lost motion assembly. It's a little spring loaded dodad located in the head directly under the middle (vtec) rocker arm. It's function as I understand it is to decrease free motion of the middle vtec rocker arm when vtec is not engaged.

If you are actually talkinga bout the vtec pins which are located inside the rocker arms, when I pulled my b18c head apart there appeared to be two plungers located in the outer rockers, these move by hydrolic pressure to lock the three arms together.
