They should be, have on every P4 I have looked at.
They provide oil to the impact points on the valve stems.

Subject: [ROVERNET - UK] rover p4 rocker assembly questions


I have a land rover with the rover p4 110 engine with weslake head.

My rocker assembly is at a machine shop right now being rebuilt. The problem 
is this:

The old rocker bushings have a small hole in the bottom and a much smaller 
hole at the top. The new ones do not.

The rocker arms themselves have a smale hole in the top as well. On some of 
the rocker arms, the hole has been peened shut as if with a small hammer. 
The machinist thinks this may have been in order to slow the wear on the 
bushings and rocker shaft. Imagine that the oil is traveling up through the 
shaft into the bushing and out the top. If one was to close the path exiting 
the top, the oil would be forced out the sides of the bushing thus providing 
more oiling...? Just a theory.

Anyway, do the holes in the bushing need to be there?

Whats going on?
