Hi!
The building process has been started and we ran into a small problem. The 4x4 sump had an oil pipe which the 2wd doesn't have, I don't know if it's necessary to put it straight to the sump as on the 4wd... can you help? Here's a picture to understand the problem, the pipe is marked with yellow.
