The tricky part of replacing that oil tube is routing it properly so the push rod cover will fit tight against the head. You have to go up from the fitting in the block high enough to go over the indent in the cover then make your bend to the right. Then make the bend up to connect to rocker arm shaft. Refer to thread from a couple weeks ago about this issue
I need to find a replacement for the brass fitting that attaches the oil line to the rocker arm shaft.
