Diagnostics Engineer :

Hello,
What is the color of smoke?
When does it occur?

Diagnostics Engineer :

regards,
Stan

Customer:

the smoke colour is a dark grey and its really heavy when i excellarate

Diagnostics Engineer :

Is there also a noticeable oil consumption?

Customer:

No andThe engine seems to be running fine

Diagnostics Engineer :

Usually grey smoke is due to oil. Besides the turbo, it can get in due to clogged crankcase breathing or valve stem seals.
But then engine would be using at least a liter of oil per 1000 kms.
So if there is no oil consumption and intake is not oiled up- please have the injectors tested at diesel service center.

Diagnostics Engineer :

Poor injection pattern can cause such smoking as well.

Diagnostics Engineer :

regards,
Stan

Customer:

I Know its a daft question but do you thinks it would be worth repairing or should I just scrap it

Customer:

regards kenny

Diagnostics Engineer :

If there is no oil consumption, and injectors test out to be faulty- it is worth rebuilding the injectors

Customer:

many thanks kenny
