My engine light comes on, I have loss of power and lots of white smoke, it is not the diesel supply as I have cleaned the tank, replaced both the inline water trap and the diesel filter. My turbo is f

you did not specify mileage on this engine.... compression may be an issue, also large amounts of white smoke pulls me over to a lack of fuel, lean condition on diesel creates this fenomena, check delivery lines and pressures,

Depends on the colour of the smoke.
Unlikely an engine will sound healthy emitting black smoke - excess fuel.

An engine could sound healthy emitting white smoke (steam from coolant) but not from white smoke (excess unburned diesel).

Most engines emitting blue or blue-grey smoke from burning engine oil can sound very healthy.

Gasoline won't make it blow white smoke. Sounds more like water in the combustion chambers of the engine...You could possibly have a blown head gasket

check your turbo again. also check whether the waste gate valve is working by testing it with vacuum tester.Or check if any flex hose on turbo or inlet manifold has not cracked or sheared and cause a leak and that is why you might have low power with lots of smoke.

for the powerstearing check the oil and refull when nessesary,turn engine on turn 5 times hole the way left and 5 times hole the way right.
check level oil again refull when needed.the white smoke on that spot
you say can leak from diesel.

on nissan terrano diesel: had a fault cose 77 and a white smoke, no power. i changed the fuel filter and cleaned the fuel line from the tank to the fuel filter. it solve the problem.

White smoke for a diesel means air in the fuel system. You will have to start at the engine, I start at the line going to the fuel pump. Get some fuel in a can, remove the line to the supply side of the pump and put another line from the can to the pump. If it starts and doesn't smoke , then you have to work your way back to the tank and find the spot that is sucking air. If it doesn't start the I would replace the filter first, check again. There is a possibility that the injector pump is bad, but these don't usually throw white smoke. They just make the engine have very little power or no start.

check the fuel filter common cause for loss of power

Engine Coolant Loss with No Visible Leaks (Reseal Injector Sleeve)

Some owners may comment on engine coolant loss with no visible leaks. Excessive white smoke or a coolant type odor coming from the exhaust pipe, along with low coolant levels, may indicate coolant in the combustion chamber.
Cause
Condition may be caused by engine coolant entering the cylinder due to a dirty or damaged seal between the fuel injector sleeve and the cylinder head.

If it's black smoke, you could have a faulty or dirty EGR valve and may not be closing 100%. Remove the EGR valve and clean it with spraying carb cleaner and reinstall after inspecting the valve can move without any binding. Goo luck and hope this helps.

if its diesel, attach a tube to pipe leading into primer pump.[black bulb ]. attach a pump . and tube from outlet of pump to container pump out diesel till empty. if petrol locate pipe feed from tank and connect to it same as earlier
