Nissan hardbody turbo leaking oil

You probably need a new head gasket and other gaskets. Oil and probably anti-freeze are leaking in to the engine works. The white smoke is almost always caused by anti-freeze.

Sorry we do not sell parts nor do we have parts locator services available.

Could be a bad oil sending unit or your oil pan is leaking or your valve cover is leaking.

is this a petrol or a diesel ??

Problem with 1998 Honda Civic Nissan hardbody 3.0td loses power and dtc code 42 must be old nissan as 98 civics use OBD2 codes.
what year, Nissan, and is this Turbo Diesel, if yes, get the FSM
its complex.ever heard of that , FSM
the factory service manual, all cars have it.

potentially you are using to fine a grade oil and the oil is seeping past rings and burning off on startup

you will have to removhe the gearbox, while you are at it check for bearing play, and it is a good time for replace the fluid and chaeck for filings

yea check the turbo....it ll be a better option..

Clean it off with degreasser or equivelent cleaner and wipe it dry. start it and/ or drive it a short distance and recheck.

Your description sounds like a waste-gate problem.
These are intended to prevent overpressure from the turbo and yours might be faulty.

The oil leaks may not be related to the other problem - Jeez, would love to own some vehicle that never leaks oil from somewhere.
