Customer Question

I fitted a new belt to Renault master 2.5 2005 G9u 754 engine,I have fitted new Bosch injectors and compression on 4 cylinders is 390/400 psi.
I have checked the pump sensor is there on TDC.
I have fitted a new air pressure sensor a new water temperature and a new turbo.The engine starts first time everytime but always gives of to much smoke,I think is over fueling going by the smell and possible pinking,
I even took the front off again looking for the EGR valve because someone mentioned that could be a cause,to find no EGR fitted.Are there any other possible causes of to much smoke.

Mark :

Hello, my name is Mark and I will try help you with this.

Mark :

It is possible the smoke is caused by oil trapped in the exhaust from the previous turbo failure.

Mark :

This can take time to burn off and can look like the engine has a fault.

Mark :

Is the power from the engine reduced?
