I bought 2004 vigo 4 months ago with 150000 km on it. the problem is that when I take the oil stick out, white smoke continously comes out of it. its not eating engine oil at all(3000km).there is no problem with the pick-up and turbo is working fine. and the other problem is that when transmission is in D, thick black smoke comes out of exhaust pipe(it only comes at about 800-900 rpm and truck is idle). the smell of this smoke is bad. A mechanic from toyota told me that its very expensive to maintain these trucks as fuel system(common rail) is not suitable for pakistani enivironment(diesel quality) Suggest me if I should keep this truck or sell it and go for something else.
