6.0 Powerstroke high pressure oil system air test 

When I test a hot no start I try to get the engine as hot as possible before testing if running it isn't possible at least plug the block heater in overnight before checking.

I have a question cause I did this exactly how you did . My vehicle when monitoring live data showed IPC building 1,500 psi extremely fast but my IPR is at 85 so I was having a crank no start. I’ve done this and found that lots of air could be heard and I mean as soon as I opened the valve cause I have the exact same tool which is plugged in the exact same way as yours in this video but your video I don’t hear anything. I isolated the noise and I believe it’s coming from the center where the branch tubing is and the J-Tube an pump is. I really hope my studying is paying off cause I had another truck I couldn’t fix and made me kinda get my hopes down on working on these trucks. See what confused me also was that the first time I did this an exposed the pump I found the pump (aluminum ) not cast iron was leaking air from the front of it. So I replaced it an closed it up an then tested again an saw the new pump was still leaking from the same are on the pump. I did some more research an found that some people say it’s normal that it’s a IPR drain Location. Others say it’s not normal an is a bad pump. So that has left me absolutely confused questioning myself wether I got a Defective new pump or if I did all that labor for nothing. I have yet to solve that mystery an here I am again dealing with another one of these trucks and the air pressure coming out was so much that when applying air that if I put my hand on the opening of the oil side after I removed the fill cap it would push my hand off. My truck is so much louder than yours when applying air unlike yours is when applying air. Please give me an information that you can when reading my paragraph cause man do I need it. I gave up once thinking I couldn’t fix the trucks but I’m trying again..

Did the air test as in this through the ipr but will this also check the hpop? If no, how do I test it? Thanks!

Is it typical for shop air to slowly bleed out of the high pressure oil system while using this method? I went ahead and updated my STC fitting while addressing an EGR cooler failure. No visible or audible leaks within my testing apparatus, or the high-pressure oil system itself. Once shutting off the air valve, I noticed air pressure slowly bleeding off by observing the gauge, 1-2 psi every 5 minutes or so. All fittings within test whip have been doped and tested leak free. The O-ring on the IPR-air fitting has also been verified leak free where it threads into the HPOP.

Ford calls for 15w/40, so why put in wrong type oil 10w30?

can air test be done without turbo and intake? I took mine apart to replace oil cooler

I just tried this and after about 15 seconds the only place i heard it coming from was where my oil filter is. Shut the air off and took my oil filter cap off and filter out and turned back. Sure enough thats what its coming from. What is that telling me? Any help is much appreciated!!!

Thank you for this video. I have to do this same test on one of these junkers tomorrow.

Would you be able to hear if a dummy/stand plug was leaking with the valve covers still on? Just curious because I have to do this on my truck.

glad to see you know what your doing! just subscribed. tons of diy people that put out content that is not as knowledge based. i don’t even have a 6.0 and i watched the whole video. i used to have an 05 and did just what you did and found bad STC fitting and injectors leaking down.

You should do a video on what to look for when buying a used 6.0. What you recommend etc.

wanting to fix the truck, and get rid of it. Well, we know he is not an honest person, and what a real jerkoff to just fix one injector and not replace all the seals etc which wouldn't cost that much. Instead he wants to dump his POS off to some unsuspecting person, knowing his POS will break down on the person soon. And i am sure he will not tell anyone that he had a bad seal etc., and replaced it, because he would have to tell them that the rest should soon follow and he didn't replace them while everything was exposed and less costly to fix. Me? I would have had all of them fix and updated and told prospective buyers that i just had the HPOS resealed with all new seals in the injectors etc. I hope he doesnt try to commit fraud and tell anyone he replaced the seals trying to make them think he did them all when he only did one! I wouldn't finish the work on his POS if i were this mechanic, knowing the guy plans to dump it off real quick before the other seals go.

Used this video and adapter to check for a leak. I was able to quickly trace it to the passenger side dummy plug. Fixed the issue and starts like a champ...So far😅. The only thing i wish i hadn't wasted time doing was leak checking an empty oil rail after the repair. Hearing the air in the system had me thinking I still had leak when i didn't.

I have an 03 6.0, air pressure testing at the IPR port, and I get bubbling sounds from under the HPOP. I changed the HPOP a few years ago, but I started getting a no start when hot situation recently. I know 03 pumps go bad a lot.

Hello just wanted to know if i was doing a leak test would i have to open the oil cap and the oil filter and the valve covers or could i just listen for an air leak with everything on? I have a 2004 f350 got good icp voltage and 1000 psi on the icp i have ficm sync and 49 volts on the ficm but the ipr was 85% and when i pulled it out it had debris on the screen and i have oil pressure

What's the valve set up? Does anyone have the specs for valves and air set up?

Got an 03 6.0 around 200k miles. HPOP was replaced by diesel mechanic 2 months ago with oem ford motor craft per mechanic when I broke down out of state and was gonna cost a G to get it towed back to the house. Now I’m back to crank no start. Icp pressure at 397psi, ipr dumping at 84, icp voltage at .23, fcim readings good, low pressure dash gauge reading well. Took out ipr and hooked up air @150 psi and hearing air from oil fill tube and gurgling noises under oil filter. Gotta guess at what might be, what to look for? Fixing to pull passenger side valve cover and see what’s up! Thanks for sharing all that you do your videos are very helpful thank you!!

8:10 “What the hell is even that” 😂 Perfect use of the meme

Before I do something incredibly stupid, do I have to drain the oil before applying air? I don't want to be blowing oil everywhere....

Happy Father's Day! If I plug shop air into an IPR test plug would I hear a leak in the HPOP (old one with BB) or does that test adapter only charge the system downstream of the HPOP? Crank no start cold 250psi HP oil. Ran great all day. Went to start it 175psi hot, waited, 250psi next day.

Question, would like to get more info from you on this, how do I get an Email?

Hi , i have a 04 f550 6.0 crank no start and i put shop air to the apr and i got air going into the coolant side, what could couse that,? Michael

Lets go Brandon

would this work for early 2004 6.0? i have the pain in the a$$ early one thatis hard to get to the ipr and icp. was running great and i shut it down then went to start it and it fired for a split second and now she just cranks and cranks but no start.

Thank you for your video help me a lot
