HPOP Air Test Questions
I have a no start issue that I believe is HPO related.
I did an air test on my late 04 6.0L but I've got some questions. First of all, when I pulled the ICP to install the air plug, I noticed oil on the tip of the ICP. My question is, is it normal to have any air at all coming from the oil fill pipe on the passenger side? I don't hear any leaks, but there is a slight escape of air from the oil fill tube with the camp removed. Is this normal or is this indicative of a HPOP or other issue?
Also, I'm towing it in to have codes pulled next week. If I do have a failed HPOP or ICP, what codes should I look for?
