Hey guys I need help bad. I am up in Colorado Springs visiting my parents had high eot temps so I pulled my oil cooler and replaced it. While I was in there I also changed out the stc fitting on the hpop to the new improved one. I had removed most of the oil from the valley when doing the oil cooler and didnt know to fill it back up. I also replaced the screen filter on the icp. I replaced the stand pipe and dummy pipe on the drivers side but skipped the passenger side because of time. Once I got it all back together i have no oil pressure on the dash gauge. It just cranks and cranks. I pulled the oil filter and it fills up in about 5 sec. Pushing down the black valve oil flows through no problem. What could I have done wrong? How can I figure this out? Many say you just need to crank it until the pressure comes up but how long before you start looking at something being very wrong? I have no code being thrown. 2005 F250 6.0 diesel.
