There are unused plugs in the harness, just so you know. Just make sure every used connector on the engine (clearly if you bypass the EGR system, the EGR solenoid is no longer used) is plugged in and you'll be fine.

 

Well today i found that one of the oil gallery going to the cylinder was stuck. I guess they both use some valve inside the oil jet. I got a new one coming 10 bucks. and the front main bearing is bad order the set of 8. and connecting rods bearings had wear too ordered that was like 84 total. im get all the stuffs for maintance oils ect. ill let yall know if something comes up again thanks for the help guys.

 

Bad bearings are the #1 cause of low oil pressure, so if your gauge was reading nearly 0psi, that's probably your cause.
