Leaking top of 3rd injector

[MarkNissan]

Hi,
I got Nissan patrol 2010 3L Turbo Diesel Y61 Model. Suddenly there is an oil leak on top of 3rd injector.
Can someone let me know what can be the reason. Only 160 000km so far.
Please let me know how to fix this. I have attached a picture.

Thanks guys

They are different between the DI and CRD zd30's so pick carefully.
About 3 beers to change all 4.

They are glow plug seals mate, CRD injector seals are not replaceable. I'd be checking its not oil dripping down from the intercooler or air piping above.
