Crawling around under the NP DID on the weekend I discovered what looked like an oil leak down the drivers side of the engine bay:
Thought it was a bit odd as it was down the side of the engine bay, not around the sump or turbo where there would likely be oil. It didn't smell like engine oil either. So I started to suspect brake fluid.
But when looking from the top found that it was coming from the diff breather (the breathers hide just under the air cleaner box).
What would cause that I wondered, and then remembered that water crossing last weekend that was just a little too deep for comfort, so I pull the drain on the front diff and found this:
Yum. The transmission (manual) was similar, so I ended up changing all the driveline fluids. There wasnt a huge amount of water in them but enough to discolour the oil. So I guess my message is to check yours after any deep water work.
