high pitch squeal,no power
My pick up was diagnosed by dealer as having failed hpop
or a leak, After dismantling engine to hpop turns out ony problem was IPR valve, great! we never touched the HPO system other to test it. put engine back together now it runs weak and has a high pitch squeal by the turbo but we can't figure it out, cant bring it to the dealer, their the people that caused me all the pain to begin with. that is the weakness of the 6.0 lack of good techs (at least in our area) to think I could have just replaced the IPR the first day , I have been with out truck for over a month. sickening just sickening. If any body gas any clue what I screwed up or some way to narrow it down. please respond
