Hello All. I've had slight leak from the pipe where it is fixed to the oil tank, i took it apart today and found the remains of a copper washer between the nut and the banjo, there was nothing between the banjo and the tank. So i made a gasket to go between the banjo and the tank, and put a tight fitting fibre washer between the nut and banjo. I'm sure there must be a proper washer to go where i put the fibre one. I tried a washer between banjo and tank but then there was not enough thread to put the pipe back on. I ran the engine for about half an hour with no sign of a leak, should be ok, would just like to know if there is a special seal to go there. Cheers. Ian.
