what do you guys think of this? customers truck came in with a long crank then start mostly when its cold. i ran diag on it found the IPR going to 85% instantly then would go down and ICP would climb very slowly. meanwhile i have base oil pressure. anyways i started digging in to high pressure system. air tested through the IPR port. heard a leak on both sides. i figured it was dummy plugs and/or stand pipes. i go ahead and update those. still hear leak toward the back. by the was this is a 04 with the wavy style oil rails. pull it apart more and find air coming out of front seal of oil hpop. i go ahead and pull it out and have a look. the ball thats on the side of it is gone and confirm leak is coming out of front seal. get a new one from ford. out of the box the ford reman has the same leak i call them and have them send me two more to experiment. i get different results from each. i put one in the has the least amount out air leakage and the truck runs like new no starting issues, no icp or ipr issues. now it is normal for those pumps to leak out of front seal? doesn't seem like it should. i appologize for the long winding back story of the diag process i know that probably bores most. anyways share your thoughts
