Thank you. I pull the worst one down this morning and found this! ill admit I used engine oil under the heads like Cummins says and it got burred. Lesson learned. I bought some new bolts today, Scotchbrite'd the cap lightly and bolted it back up with Lubriplate this time. At first it tightened up the same 140 degrees but I kept impacting and impacting and it eventually went the full 180! I also got all the others to go the full 180! I just needed to impact them more, with 1” gun and when the compressor was at full 150psi. Most of the turns came from the initial pull of the trigger so I think I may have a flow restriction issue in my compressor lines somewhere even tho its all 1/2” hose & couplers. I think the real culprit tho was oil under bolt heads not good enough lubrication. I was able to get them all to 180 degrees, thank you guys much for the help!

The only thing left to do is prime it with oil. I just ordered that pump you linked, Tyvm. I got m14x1.5 fitting today, do you think i could get away with using a hand pale pump into the port5 (while my dad bars the engine over?) Or should i wait for the amazon electric? another day or two off isnt the end of the world. I didnt realize you pumped in thru port 2, Ty for that info. ill go first thing in the morning to buy a fitting for that port. i like your idea of leaving the oil pan open to pump the oil thru multiple times. Is your inline oil filter the one that comes with the amazon pump or different?
