I have the 1.3 engine and i was just checking the oil cap and I saw it being like this. I haven’t seen it be so brown in any of my previous cars, is this normal? What could it be? Moisture?
The brown stuff you see is indeed condensation from within the engine. The color ranges from brown to a thick yellow-white mayo-like sludge. It often means, but not always, a failing CCV. The CCV is supposed to vent the crankcase (like a PCV) and allow this condensation to flow back into the sump but it gets clogged by an accumulation of this condensate. In colder weather, this condensate clings to the CCV pipes/tubes, as they do not warm sufficiently on short trips to flow back into the CCV.
Best to avoid short trips and allow the car to warm sufficiently.

Thanks for your reply.
I only picked up this car 3 days ago and it was serviced before my pickup. I cleaned the residue and i will see if it shows up again as i don’t really tend to do short trips - so i am wondering if it’s from the previous owner and the mechanic didn’t clean / check it?
