I've been thinking about this.. first and foremost, doss is right and has provided the best advise yet.. second, I'm now of the opinion it is not on the high pressure side.. if it was, you would be spraying the engine bay at operating pressures riding down the road.. there would be no way you couldn't notice it while driving as your engine bay would smoke it up quite a bit..
While working on heads, if they were pulled during studding, the valley would be exposed, and the hpfp as well.. the hpfp would also have been bled during reinstall.. the low pressure return line is opened in such an event, and air is purged..
Where specifically is the fluid visible near the heads? If its near the back, I'd suspect that low pressure line is the culprit.. where it was loosened to bleed..
If it was a high pressure injector line, you would without doubt have contaminated your oil.. there's not much room around that..
Whatever it is, I'm willing to bet its on the low pressure side, and the return makes sense because of the need to open it to bleed, but also because the high pressure system feeds back to it after you kill the engine... That pressure has to go somewhere, or remain contained in the rails.. as it is, its returned to the hfcm/tank.. but In your case I bet its, instead, escaping at that bleed point and leaking down the block..
Maybe, anyway.. I dang sure ain't no expert here..
