Well after poking around I figured out why the rail pressure was spiked. There was a plug unplugged for e regulators. So it appears that the injector quit leaking. The rail pressure was running wide open at idle. Now even still that injector should not leak correct? Will extended periods of max rail pressure cause seepage. It's just a drip when spiked and it's on number one injector and it's coming from under the hold down. What does everyone think?

You should be leak free regardless of how much rail pressure it idles at (up to 26k :D).

C here's my concern. First the sticks have not been out to have anything obstructing the seat. And I agree on the leak free. However efi only reads to 26000 if it sustained god knows what number for a extended time would at cause a momentary leak? It could of been 35000 for all I know with twin fuelers.

if your all plugged in now and ramp it up, are they any leaks? i can understand if there was some leakage that high but you would see pump failure at 30k, atleast thats what i have read on here before so take that with a grain of salt

Yeah I'm just trying to b optimistic. The prob. Now is tracking down the correct injector. The one leaking is inj. 1 however I have a bad balance rate on 8 according to efi. Now unless the numbers r not crossing correctly which I know has been a past problem, then I have two bad sticks. But I find that hard to believe. Also it seems to run and sound fine also.
