I would remove this rocker arm.  It is an 11mm nut that holds it on and do
not loose it.  carefully remove that wire piece that retains the pushrods
first.  Now at this point there is no pressure at all on the valve stems.
Do they line up the same on intake and exhaust on number one, or is number
one sticking out further from the head?  I f both are straigt, proceed to
next step.

Then I would remove the pushrod.  I would look down in there and see what is
going on with a flashlight.  My best luck in removing the lifter is to hook
it with a seal puller, although sometimes a magnet pulls it right out.  My
guess is that you will see a lifter that has lost its snap ring and fell
apart.  Maybe not though.........It could be a collapsed valve seat meaning
a new head........... If so, not the end of the world, either.  I would
sheck the strainer and see what sort of metal is in the screen before
committing, though.

The hydrtaulics are the lifters...they pump up eith oil.

Tough to say without more info.
