This question has not been answered and thec answer would help us be certain that our posts are correct.
LONGBOX55: "If you have an external line, then it would seem that somewhere along the line a po has done a backyard repair to fix a blocked passage/oil line."
" the head turns out to be a 55 it has no hole down through the head "
The year does not matter in regards to an external oil line from one side of the block to the other, no matter which high-pressure 235 engine year (1954-1962). Such an external oil line might not cause any harm but it is not the original plumbing and it was most likely done because of a blockage in the stock oil line (behind the push-rod cover on the distributor side of the block) that runs up to the rocker arm assembly (as posted by LONGBOX55). | | |
