06 f350 died and wont start
 

I am working on an 06 f350 it died going down the road and wont start it has 134000 miles I did an air test on the hpo system and I hear a lot of gurgling under drivers side valve cover I have checked the ipr and seems to be working fine the only code we got was a p2291 I was told that the last mechanic had upgraded the stc fitting as well can anyone tell me what this gurgling is? Is it a bad hpop or what could I do next. I don't hear any other air leaks

Thanks

might be your rail on that side leaking ..i would take off the valve cover and do the test again ..might be able to see were the leak is....scott:humm:

I had the valve cover off today I took the oil filter off and did the air test again and the gurgling was right under the oil filter from what I have read the hpop is shot would you agre

not a ford man but if thats were the gurgling is coming from them thats were i would tear into...keep me informed knowledge is good stuff...scott:humm:

I will keep you updated thanks for the replys

Well pulled hpop today did an air test on pump alone and the air was coming out the seal around the shaft that is what was making the gurgling sound so if someone tells you that is normal to have a gurgling sound I think they are wrong just my opinion

Good shot....glad u found it...by the way thanks for the heads up....scott
