OK so I removed the oil rail and the number one injector is the only injector with no oil in the top bc where the nipple cup seats. Numbers 3,5 and 7 injectors all have oil in them. 1 is the only injector with no oil on top of it. I think I am going to replace the number one injector and retest

Re-test failed. I installed a new #1 injector from Ford after oiling the o-rings, Torque to spec, filled the top of injector seal with oil, installed and torqued the oil rail. Plugged in the air and same leak. I thought I read somewhere that the oil system can still leak if not primed or actually run? It makes no sense to me, I will have to think more about it over the weekend. I am done for today, taking the woman out for dinner/drinks then enjoying some good music by a greatful dead tribute band ...

Tom how loose were the nipples going into the injectors? When you pull the rail later clear all the oil out of the top of
each injector and with a good light and magnifying lens inspect each top injector seal for erosion. If the O-rings that
seal the nipples to the rail are worn you get a high pressure oil spray that will erode the injector top seals.

Moving them should not cause a leak. Sometimes they get bumped and you have to move them so that they go into the injector easily.
The ones to worry about are the ones that flop around. Did the photos of the deadheading plug make sense to you?

Not really Sean. Looks like your disassembling the upper portion of the standpipe section? I didnt fully understand and kinda went In a different direction checking the STC and such.

The dead plug lets you cut all oil to one or both heads and with the OTC tool you can still
use the ICP sensor to see what pressure the pump is putting out. Sometimes when you plug
one side you can get a start just running on the injectors in one head. When you plug both
then your testing the branch tube back to the pump and the pump. One other thing you can do
with an extra dummy plug is air test just one head by using the IPR sensor port on the rails
at your air input location.

Found the problem ! While trying to start it this morning got it running and as per the usual, checked for codes. This time though, I had two codes. Both related to the cam sensor. A P0341 and a P2614. I already checked the cam sensor pigtale so I bought a new sensor from ford and installed it. The one I pulled out had a torn O-ring towards the metal end. the red O-ring. Anyway, Put it in and BAM, runs and idles for ever. What a weird problem. Starts cold, idles for 3 - 4 minutes then dies. HARD to restart. All symptoms of a HPOP leak. I will take it on a nice long ride tomorrow and update but for now, thought I would let everyone know it was a $38.00 Cam Sensor !
