my friend's subic gen2 4d56TDIc pajero has been showing signs of oil coming from his turbo. When we pulled the hose going into the intake manifold, some engine oil came dripping out of the tube. It didnt look like EGR condensate at all. The intercooler was so dirty and filled with oil. The EGR tube from the cylinder head cover to the turbo intake hose (air filter to turbo tube) wasnt really wet.

where could the oil be coming from? What could be the cause of this? :roll:

thanks peepz! peace!
