I have determined that i have a high pressure oil leak and i am trying to determine the location.
I have auto enginuity software and when i perform the air leak test i can definately hear a gurgling and a slight breeze coming from the oil filler neck.
I am fixing to remove the passenger side valve cover to find the leak but i just have one thing i cannot eliminate......I would like to verify that my IPR valve is working.
When i am supplying air to the system and i actuate the IPR valve through the AE software i dont hear any changes in air flow or anything.
I guess my question would be...If the IPR valve were stuck open for some reason would that allow air to escape through the filler neck? When i look at my IPR duty cycle when i actuate the IPR valve is shows 84%. Is this a true reading or is this something that the pcm is telling itself to start?
I have a 2005 f350, I had replaced the STC fitting, oil cooler, blue hose, bypassed egr etc. last year and she was running absolutely fine up until it just quit going down the road.
Thanks in advance!
