I have a Focus Mk2, one of the first produced in December -04. Now I have a leak between
my PS pressure line and the union nut at the pump site. I removed the old nut
(witch you’re not supposed to be able to remove) with my angel grinder and a lot of patience...(half an hour).
Bought a new nut (3F656-6742740, the same as where fitted from start, 3F656-4747355
is too long and won’t fit) witch I screwed into the pump by touch. I don’t have a torque wrench
at the moment. Then I pushed the pressure pipe into the nut. Bent the bracket back and
fastened the last bolt.
With the accessories belt back on and oil in the reservoir I cranked the start motor
(without the sparkplugs) and a beam of oil came from between the union nut and the
PS pressure line . So the o-ring inside the nut is obviously not dense.
Does any of you have any tips or ideas of what I am doing wrong, what I can do otherwise?
Have any of you done this job and did you do it like this then?
