I was looking over my chiltons -- can't really make out how the overhead cam in the 2.3 operates the valves. The drawing isn't all that good, it's a bit smudgy.
Can someone explain how the OHC operates the valves?
The easy way to describe it in detail: pull off your valve cover.
The hard way: stationary hyd. adjusters (lifters) on one side, with followers under the cam, and the valves on the other side.

Its a very crude drawing, but it should at least give you an idea of how an OHC engine works:

thanks Harry, that helps a lot.
further question: does the lifter actually lift? or just sit there.
and if it's hydraulic, why?
The hyd. "lifters" put pressure on the followers to keep them from claking and falling out.

There is a check ball and spring inside the lifters, oil pressure causes them to "pump up", which allows a little dampening of the force used to open the valve kinda like a shock on your cars suspension, eliminating the need for adjusters like you would see on a solid lifter motor. the fluid action of the oil in the lifter is where the term "hydraulic" comes in.
In the process of a rebuild and am taking pic's as I go... let's see if I can figure out this image attachment thingy...
thanks for the pic.
I think I've got it figured now.
