Navara Problems

[Hocko]

hi guys i would just like your opinion on the proplem with my navara d40 it's blowing oil from the turbo through the intercooler back into the engine . any suggestions wat it would be and how can it be fixed?

Most likely the blow-by (pcv). It enters the inlet pipes just prior to the turbo

+1 on the blow-by. There won't be a large amount of flow, but it'll add up.

Reduce it by installing a catch can. You can't remove it altogether without breaking the law, because venting the crankcase gases (which is exhaust gas + vaporised oil) to atmosphere defeats emission controls.

If there's a huge amount of oil, check your oil level. Our diesels don't like to be over-filled.

unless its more serious like a seal or the like, what they ^ said.
