OK , thanks for your quick reply. I modified the post , you can look at it again. Thank you sir.

The D4 is a type of engine technology geared at improving mpg, but when it develops fault it is hard to fix as it is not even native to us here.

Most technicians would advice you buy the normal 2.0 engine than the 2.0 D4 with VVTI.

Also if changing engine, make sure it was fitted into that car not from another Toyota product.

Thank you sir. Understood.

Okay, here are a few things that could be wrong with the car:

1. owner is cheap. How could you drive a diesel till it runs out of gas? Jeez. As fuel economical as it is?
2. Injector has gone kaput. Owner must have been riding low all the time and it has come to bite him in the bumIt shares same pump with petrol cars at least for my skoda, it is same. I assume it would be same with Hilux. Fuel pumps last longer in diesel cars cos the diesel lubricates the pump better than fuel.
3. Bad injectors. Owner must have been buying kpo fire to have such an amount of soot spewing from him exhaust and must have knackered his injectors with his bad attitude towards quality fuel. Unfortunately, he has a hefty bill to pay for this negligence. Diesel injectors dont come cheap!!!
4. Air in fuel line. Assuming owner is a cheap fella and decides to use a petrol engine mech to fix a dud diesel engine, he is in for a long painful and arduous day. The petrol mech wouldnt even know where to start bleeding the diesel lines and injectors from. Skoda has a self priming system at least in the 06 and up models so mechanics dont have to sweat it out after changing parts. i dont know if hilux diesel engines have this feature.
5. Electrical problems. New diesel engines use eletric solenoids fitted to the injectors to control quantity and time of delivery of diesel unlike the old models that used a mechanical system. These solenoids are controlled directly by the brain box. A good electrician should be able to sort this out.

It is actually a jolly ride. There are a lot of diesel hilux mechanics in PH. All the trucks on our highways run on diesel engines. Actross trucks run on complex diesel engines and mechanics fix them here in Nigeria.

I once met a fellow on a trip who owns an Audi A3 with the gen 1 1.9Tdi engine. We got talking and exchanged numbers. One month later he calls to tell me his timing belt snapped and his car is grounded. I gave him the number of a mechanic who works on my skoda and they got talking.
The mech changed his camshaft, some bent valves, valve cups and seals, fitted a new timing belt, primed his pump (the Mk1 engine needs the high pressure pump primed) and started the car.
Car drives like a dream again. Meanwhile when the belt cut, dude was already thinking of buying a second hand engine as he thought his engine was gone and he didnt have any mechanic till he remembered me and gave me a call.

L300 buses in onitsha all run on diesel and they are still on the road.

My mech just changed the timing belt on a 2009 skoda octavia tdi two weeks ago. People said it was impossible but he laughed them off. The engine roared to life after three starts and has been fine ever since.
Don't let peoples fear fear you.

I stay in PH but i am currently out of town.

Is your mechanic in Lagos?
