2007 407 HDi 2.7 diesel injectors leaks

Post by 407 »

Seems two of the three front diesel injectors have a bit of a fuel leak as per pics (5U3G-9K546-AA)

I've tightened up the hold down bolts and line nuts but still get a bit of diesel leakage

The middle one is nice and clean, whilst the other two are brown all over , so hard to tell where the leak may be. No obvious seepage when running

My quick research is either the bottom copper washer is leaking or the middle gasket its leaking, or both or maybe the fuel return line O rings

Any one done these and any tips eg what can go wrong ?

They seems very expensive new.

regards

Thanks

any special tools or adjustments, or is it just bolt / screw as tight as you can
