i just finished my first 6.0 inj replacement

[hazard]

hey guys just replaced my first injector on my buddies 05, everything went great it had the old style dummy plug and standpipe so i installed new dummy plug and standpipe with the plastic washer and o ring, when i installed i didnt realize i wouldnt be able to get the entire standpipe through the oil rail and down into the head as a whole so i obviously pulled it apart and tried sticking the lower have through the oil rail and into the block but the hvac box wouldnt let me get her done so i massaged the protective cover on the hvac box with a hammer and was able to slide the pipe down through with no hesistation, then i slid the upper part of the standpipe into the lower then threaded them into the oil rail, the rest was smooth sailing, got everything all together removed the fuel psi reg and installed the blue spring reg and new fuel filters, i primed the fuel system and started the truck, it crank for a while but i didnt find it excessive, sounded and runs great no more fault code for injector #3 circuit in the system, no smoke no miss. took down the road about 2 miles round trip and back to my shop, truck never missed a lick, got back let idle for a min, shutdown then restarted and it cranked a bit long but fired right up and run great i did this numerous times but for the most part stays the same. i monitored icp with my mac mentor and it dont really slowly build psi, it more or less cranks then bam his well over 500 psi and starts up good... my question is, do i need to take this thing out and drive it some more to rid the system of air???? only thing else i can think is i f'd up the o rings on the standpipe... i hope not but i dont see why it just in the snap of a finger get icp and fires up i would think if a o ring was cut it would slowly build and start sluggish? keep in mind im a newbie to 6.0 inj replacement. i also took care when installing the oil rail to install a few bolts to guide it before is lightly pushed them down into the injectors and then torqued obviously. please any help or suggestions are appreciated.

They've been known sometimes to take 30 miles or so to get the air out of the system. Drive er around for a bit and see what happens. Good luck!

not that anyone may care but i wanted to say that i took the truck on a road test tonight for a while got it up to operating temp, came back to the shop and let sit with the oil hot and restarted an all was well its starting normal! woo hoo! lol just needed to get the air out of the hpop system. fwiw, if anyone does injector replacements on there own they may want to make sure they road test them for a good bit and get to operating temp before they try and restart and jump to high psi oil leak assumptions. i also monitored ect and eot and noticed a huge delta... looks like i will have some more work to do for this customer in a week or two!

Congrats, glad to see it worked out for you...

For future work, the stand pipe will go in there in 2 pieces. I think I read in your first post you figured that out.

Next time you have a space issue on the passenger side, you can remove that cover with 11 screws that are all 8mm. This will allow stud installation in-cab
