Anyone know the size of the O ring that goes on the metal cooling pipe that plugs into inlet manifold?
No time before Xmas to order the genuine article and have it here so am going to have to go for a best guess and the original's in 3 bits.
The groove is 19 dia mm x 3mm. OD of pipe is 22.67mm
O ring looks like it could be 2.5mm
Long shot, I know...
