Oil and air leaking from first coil pack on top of engine

[knz1029]

I have just noticed oil and air spraying from around first injector on my 2003 c class coupe CDi, please help how easy or hard is it to fix

Forgive my doubts, but I'm pretty sure that you only get coil packs with petrol engines. One per spark plug is the norm I think.

With CDI (diesel) engines you should have glow plugs and injectors.


Edit: OP has edited his original post and removed 'Coil Pack' from his text. I haven't lost the plot

Yes your most probably correct haha, do you know how to fix oil and air spraying from the first one of them on top of engine

 

[grumpyoldgit]

Injectors usually require special tools to remove them after years of prolonged use, so I would suggest you take it to a good local independent Merc specialist to have it done.

Please help oil and air spurting out 1 of the injectors on my 2003 c class CDi

So does it need a new injector or maybe a seal or something simpler

It sounds like the seal has gone on the injector.

IF that is the case, you need to remove the injector, recut the seat, renew the crush washer and replace the injector following the correct procrdure.

How do I recut seat? And do I ask for crush washer at automotive shop ?

What engine does the car have - i.e. is it 200CDI / 220CDI / 270CDI / 320CDI etc?
