been running into a few unseen issues with the 6.0 lately.i was doing a hp leak diag and had the turbo off so i could listen with my ultra ear in the oil return of the turbo, when i noticed oil blowing out of the turbo supply port.i had a jumper hooked to the ipr to close off the system.ive done this test a hundred of times but dont remember ever having seen this. any other tech seen this.thanks a million and merry christmas to all.

 

What year is your truck?

 

07 f250,4x4 auto, with 109 k on it

 

here is a couple of videos with the same type of problem you are describing, first video is the trouble shooting and the second is the one were he shows what the problem was. https://www.youtube.com/watch?v=SHBJ9az4PbE and https://www.youtube.com/watch?v=8xINkit3KfA hope these help

 

Actually im not sure how much they will help with yours being an 04 the HPOP is different, so I would have to wonder about the STC fitting and since you are in that far have you done the stand pipes and dummy plugs?

 

dummy plugs and stand pipes new and has the hard thread pipe fitting on the oil pump.no hp leak found.just getting air back threw the oil cooler.if you got ipr closed i didnt think that you would have air coming out of any base oil pressure ports.thinking that the pump is worn internally. ive got this yruck cause its been at 3 other shops with parts thrown at it.no start hot.so im the lucky person to get the job . not complaining.i like jobs that make you go"i aint seen this before"

 

I would suspect the IPR before the pump

 

At least the IPR is a much cheaper part than the HPOP, so if you change out the HPOP and that doesn't do it and it ends up being the IPR that would suck.

 

got a new ipr in it also.sorry. forgot to add that. working with the flu sucks.my brain aint up to snuff.

 

Any time you get air back-feeding through the oil supply side while air-testing the high pressure oil system for leaks, that's always been one sure fire way to condemn the HPOP itself. You may want to verify by using the block-off tools to dead-head the pump to check its output. But to be honest, the '05 to '07 style pumps very rarely fail, compared to the '03/'04 style pumps. Now, that's not to say it's not possible either. Hope this helps.

 

That is good to know Mchan thanks for chiming in
