Hi, my 2015 Nissan Navara np300 I have noticed a fair amount of oil in the intercooler hot pipe. Mechanic's Assistant: When was your last oil change? 5,000km ago Mechanic's Assistant: Are you fixing your Navara yourself? What have you tried so far? Not tried anything as yet Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I have catch can fitted, checked engine dipstick and looks like its losing oil at a substantial rate, not smoking excessively from exhaust

Hi my name is \*\*\*\*\* \*\*\*\*\* I will be assisting you today. The system will offer a phone call automatically please disregard. Have you inspected the turbo at the charge air outlet?

Hi Jose, no I haven't inspected inside the turbo yet. I suspected turbo might be the culprit but wanted to check there's no other possibilities before I go pulling it apart??Ive just noticed an oily residue on my air filter too??Hi Jose, No I haven't opened up the turbo yet to inspect. I suspected turbo could be the culprit but wanted to check there's no other possibilities before I go pulling it apart??

Some of that oil can be from the catch can but I would inspect the turbo then go from there .

Any clue as to how im getting oily residue on my air filter?I believe pcv valve plumbs to just before the turbo intake, not through the air box
Automotive Expert
Ok so different set up. I would suspect the turbo as well. But from the intake side as well as the charge side.

ok, just hypothetically if turbo is fine what other causes could be possible?
Automotive Expert
Not to many places oil can come from to the filter. Usually the only other thing tied up besides the turbo is the pcv system.

I’m still struggling to understand how oil from turbo can enter air box?
