I had a suspect injector in number 2 that I replaced with a used one that I THOUGHT was good, but when I fired up the engine after replacing it, it ran a bit worse than before I replaced the injector. I thought maybe It has been sitting too long (came from a shady independent shop) so I let it run for a bit to see it it would smooth out.
Then I noticed oil streaming out from the back of the head area. I tried to see exactly where it was coming from thinking I had blown a seal in the turbo or something, but it actually looked like it was coming from the union where the right up pipe joins the Y collector and goes into the turbo.
I put the original injector back in, cleaned up the oil mess and fired it back up.
No more oil spewing and it ran OK. Obviously my up pipe(s) are leaking, but I'm guessing that somehow the bad injector allowed oil to get into the cylinder where it found it's way out the exhaust and to the leak in my up pipe.
