Correct Jose as I said above. Christian. Each of the 3 terminations of the Y pipe has a banjo fitting. 6 copper washers required to seal them all. 2 per banjo joint. These banjo joints are not separate they are part of the cam oil feed pipe. Check the pipe for cracks if the new copper washers do not fix the leak.

You can also soften harder alloyed copper washers by annealing them,,should they fail to seal properly. This was a problem with aftermarket seal rings used at fuel filter banjo fittings back in the day (think W116 and R107 Mercedes cars).
there is a thread here about the thickness of the washers.
the poster could not cure the leak even with new washers until he found out the washers he was using were too thick.
worth investigating that thread.
Is there another thread here other than the one I posted in my first reply? I would like to read it. You can use Stat O Seal washers but some of them are too thick. I don't even have sweating using NEW C4146 copper washers.
Get the correct washers with squash rings as per picture in Jose's posts and the other thread Glyn linked to.
Oh and just for interest Chris tian the washers are copper, the Banjo in your picture is brass, some of the new ones are plated, but I actually don't know what they are made of, in my opinion the Brass ones seal better than the plated ones, it may just be coincidence but that's my experience.
Good news! The C4146 copper washers with squash rings are really designed to be used once & replaced every time you break the joint which should not be very often.
