This my be me trying to find a different problem than i think i have but The past few days my truck has had some extended cranks when warm. Excuse me it is a 05 6.0 75k bpd oil cooler, bpd egr cooler, sct towing tune. stand pipes, dummy plugs, stc fitting, oil supply and drain for turbo, blue spring, 6.4 banjos and injectors were all replaced in dec of 11.
I know that this all points to bad hpop or hpo leak but then i think 05 hpops are rare to go out and i have all updated parts in. My heads have never been checked and i do see some foam in my degas but there are no signs of oil(bpd cooler) no smell of fuel and it doesnt puke. I hooked up the scanner and it has a p2285 and p 0272 (non-mil and neither are active) one is icp pressure and the other is #4 cyl contribution I have a AE scanner coming from BPD as we speak to check HPO pressures. The truck fires up good cold and always starts but when warm it takes 10 -12 seconds of cranking with no oil pressure on the idiot gauge until right before it starts.
I dont know enough about the Oil pressure regulator to be sure either way but when i pulled the allen bolt there is slight pressure from the spring going back in. Not a lot of pressure but i can feel it there. Is this ok?
Or is this suppose to be relaxed till just before the bolt is tight and the oil pressure puts the tension on the spring. There is no noticeable foam in the pan to point to a cracked pickup tube and even then i should have low lpo at idle correct?
I guess my main questions are has anyone ever cracked a head where it could effect HPO? Also any info pertaining to the OIl pressure regulator (behind the dampner). How to tell if its bad?(lots of spring pressure or any at all) or does this sound like injector O rings
Thanks in advance for any help you guys made my life alot easier when putting the bpd kit in
