DynoMike said:Hi Adam. I would hazard a guess that it may be coming from the union nut that you can see in the photo, but being blown all around the area by under-car air flow.
If the whole of the scavenge pump is wet then it could be the o rings behind it leaking. However, the nut looks very clean, as if that may be the source of the leak.
Either way, good luck.
Glad it turned out to be the scavenge union, had the same on mine a couple of years ago hence posting the above previously. As for noise, yes they do tend to chunter and grumble a bit as standard, some more so than others. 9e are obviously dealing with these cars on a daily basis so if they say it is normal don't worry!
Happy you have it sorted :thumb:
