Is it easy to fix a leaking injector in a Mercedes C220?
I have been told by a merc specialist that it not the injector but the seating washer which needs repalcing. This only costs £ 20 for 4x washers and the sealing paste. The question is is this something I should attempt? – I am not afraid of the work or that I would not be able to do the job.
How to fix a leaking CDI fuel injector?
After you’ve disconnected fuel and electrical parts (great care due to high pressure etc), you have to remove the two small screws which hold the injector clamp in place. You will probably need a form of slide-hammer which is screwed to the top of the injector, to get it out. Not a job for the feint-hearted!
Is the Mercedes CDI injector leak in the Honda washer?
This engine, along with the van itself has covered over 500,000 hard courier miles and although the piston rings/bores are now nearing end of life (increased crank case pressure) it still sounds sweet and runs like a train.
What causes fuel injector to leak and cause hard starting?
Leaking fuel injector can be cause of hard starting. This is because the fuel rail pressure has dropped and fuel has leaked into the manifold and causes the spark plugs to become flooded. Both top feed and side fuel injectors make use of O-rings to seal between the fuel injector and fuel rail.

Replacement fuel injector seals and washers are cheap and are, fairly easy to install.
When do you Know Your diesel engine injector is bad?
If the Cummins engine won’t run at all, then the injector is usually cracked so badly that the fuel system can never reach the threshold. The oil will also be heavily diluted with diesel fuel. By installing the cap on each cylinder one at a time, the bad injector can be isolated — you’ll know you’ve found it when the engine fires normal and fast.
How does oil get into the injector in a diesel engine?
This movement of the spool valve is only 0.017˝. When the open coil is energized, the spool valve moves to allow high-pressure oil in from the rail to flow into the injector. When the closed coil is energized, oil is allowed to drain from the injector into the crankcase.
Can a 5.9L diesel engine have a leaking injector?
Whether you’re dealing with a 5.9L or a 6.7L engine, you should understand the process of elimination of each injector on common rail Dodge Cummins applications in order to isolate leaking injectors.
What causes a fuel injector to leak over the engine?
So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.
