Jarrid,
        I have never seen any o-rings installed (not a bad idea to cut some
grooves for some) and I just checked the Rootes part manual and didn't
see any listed. The 1600s & 1725s that I rebuilt never seem to need them
and oil pressure is way up there. One point to make on the rockers is to
clean the oil holes, both the adjusting screw hole and the oil hole on
top. They are pretty small in diameter and they do get plugged with
carbon. Check the oil holes in the rocker shafts too. Make sure all that
stuff is clean. Most rebuilders throw in some rings & bearings and never
touch the rocker shaft assemblies at all.

I had a customer's 1725 that had low oil pressure and I found that
someone had installed the oil filter base gasket on backwards. Once a
new gasket was installed correctly, oil pressure was back to normal. 

The Alpine engine is a simple design, but the rebuilder MUST look at all
the small details.
