Diesel Injectors need attention at about every 70.000 to 100.000 Kms

Common Rail Injectors
A new injector could cost you between R1600 to R5000 each - so can you afford not to send them to RODAC DIESEL for repair or servicing of your common rail injectors

We also service Petrol Injectors

Black Smoke

This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for :

• Faulty injectors, defective or incorrect atomisers. (injectors need attention at about 100.000 to 120 000 Kms)
• Faulty injector pump   
• Incorrect fuel injection pump timing or incorrect valve timing.
• Poor engine compression
• Dirty air cleaner
• Turbocharger or intercooler faulty, poor boost pressure
• Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)
• Exhaust system restriction
• Defective "Thermostart" (Cold starting aid)
• Incorrect valve clearances.

White Smoke

Normally means that the fuel injected into the cylinder is not burning correctly.  The smoke will burn your eyes.

• Engine/pump timing out
• Fuel starvation to the pump causing the pumps timing not to operate correctly
• Low engine compression
• Water/petrol in the fuel   

Blue Smoke

The engine is burning engine oil

• Worn cylinders or piston rings
• Faulty valves or valve stem seals
• Engine over full with engine oil
• Faulty injector pump/lift pump allowing engine oil to be mixed with the diesel
• Incorrect grade of oil used.
• Poor compression
