Leaky injectors 200tdi

I recently noticed a smell of diesel from the engine bay. Had been no whiff at all up to now and all of a sudden, a strong smell. The clutch and Dow pipe have been replaced but other than that, bo work so I suppose just coincidental timing.

Had a look yesterday and can see that diesel is leaking out where the injector joins the head. On number 1 cylinder I can see it bubbling while the engine is running.

I am assuming the problem is with the copper sealing washers. Any thoughts as to whether I should try and tighten the injectors a little first or pull them out and replace the washers?

Thanks.

You could try to nip them down a little to keep going. Have a look regardless and check the securing nut hasn't become loose or the clamp hasn't banana'd...

But in the longterm yes you need to replace the copper washers.

Given that a set of washers is less than a fiver it does make sense to replace. I have ordered some.

In the meantime, the only one I could get a socket to was number 1 so I checked the torque and it was a fair bit below the recommended 18 ft-lb. I have nipped them all up a little and cleaned up around. I'll take it for a spin and see how it is.

Thanks for the replies

Set about replacing the washers this morning only to find that the banjo on the fuel return on number 1 injector was loose. Very loose.

Took the injector out, cleaned it and replaced with a new washer and then ensured the banjo was tightened. On checking the others, although not loose, they were not tight. All nipped up now and seems OK.
