Doesn't sound like an injector seat leak,
they tend to cover the entire injector with what I can only describe a crap.
basically it's a mixture of combustion gases and oil.
black/brown crud from where the injector enters h head all the way up the body.
Your pretty specific,
the pipes that connect all the injectors together and then return from the end one are there to return excess fuel from the injectors back to the tank.
Fairly low pressure but constant.
any of the 75mm or so long pipes can leak,
or the plastic branches that fit into the top of the injectors.
and it will drench the head/injector filling up the space round the injectors.
And to be honest the hardest part is getting it clean!
I cover it with a rag then used compressed air to blow the fuel into the rag,
still a filthy job though.
If you were to do that then start it I sure you'll spot where it's coming from.
Don't know how many of these I've done.
As stated not a hard job,
filthy and very fiddly.
