I bought an '06 6.0 350 Lariat SD, I know its a Hi Press. leak at the STC fitting. FORD wanted to put in a new IRP if they were doing the repair, is it necessary to replace or were they fishin for more dough. At 1400+ quote, I'm gettin dirty and learnin'. Is there any Tips or tricks, the pros know to make this easier, any input on trouble spots, or other repairs to do while I'm in it this far. I know this subject has been covered to the hilt on the site. I just wanted to get some current insight and knowledge from the experts on here 1st hand. Just got MIL light, been stalling at lights or St. signs..Fuel pump or regulator, haven't even checked it yet. Thanks for listening, wish me luck if it will help. Diesel newbee I guess I am, about to take care of that too. Appreciate any and all feedback I can get, I'm also shoppin for a scan tool to get on the quick side, any info you can offer as to brand, new or used, etc.....???
Are you doing the STC fitting on your own? If so send me an email at polaris_440_69@hotmail.com and I will give you some tips that I do that can and will make the job a bit quicker. Honestly you dont need to do the IPR but I would remove it and check the screen to make sure its clean and no metal contamination. The screens are available seperately from the IPR. Good luck, most guys uses gauges and the insight on this website for most of the diag, being a dealer tech I just have the IDS at hand so its kinda nice.
I am having basically the same issue...however I've already replaced the STC...does anyone know of a Laptop Scan Program that is freeware...shareware...that will run a contribution test
I have a 2006 f250 with 75k. I am the second owner. From what I know about the vehicle the only problem reported before I bought it was the oil cooler was replaced early on at about 15k or so...
Heres where we are today. I have the bully dog pmt installed. My truck started having cold start idling issues...randomly at first. And then it became an every day thing. Then my PMT showed cylinder 1 imbalance code I can't remember the code now like p0276 maybe...anyways I replaced cylinder 1 injector and that helped for a week or less. After the week the cold start idle problem was back and persistant. Then I had a time that took me about a minute to start the truck after running in and out of a store. About 2 weeks later I stopped it to bid a job, and then went out to start it again and no go...I waited up to an hour before towing it to Ford. Ford told me it was the STC fitting...and wanted 2600 bucks to repair the issue. I'm not rich so I towed it home, and replaced the STC fitting...I would of loved tips then... anyways the truck started but still has had issues starting when hot. I thought it might be air in the system. Sometimes it would take 4 seconds to start sometimes 30 seconds...not sure what made a difference. I do know that when the oil temp is at 140ish is when the rough idle goes away from the cold start... Now today I have another no start at all situation. So here is what I am asking...could it of been something other than the STC...obviously something about the IPR pressure made them think STC...I suppose it could be the pump? I checked with my local ford and they want 900 just for the pump not installed... I am not quite clear on how to do the Air Test on the Oil Rail so help with that would be nice too.
As for you the ICP sensor in the RH head can be removed and find a fitting that will thread into there and put an airchuck onto the fitting to air test the system, the best way to do this is with both valve covers off and the HPOP cover off to verify where the leak is coming from. But from what youve described I am almost thinking it sounds like a HPOP concern. I would still air test the system first to verify that you have no leaks at the stand pipes, or the dummy plugs. Also are you using the motorcraft filter and ford oil filter cap? If not remove your oil filter and check to make sure the pipe inside is not broke. But either way put a ford filter and cap on it. My buddy ended up taking the ICP sensor our catapilier dealer and they had a fitting that had the same threads and I think it was 1/2" on the other end to put a air line nipple on it to air test his own pickup. Goodluck!
Also do you know for sure that your ICP is low? You need a minimum of 500 psi to start the truck. If you know someone with a scan tool or insight you should be able to monitor this and check, if not i believe there is a writeup on here somewhere to know how much the pressure is by voltage checking the ICP sensor when cranking.
Thank you for the quick reply. I am using motorcraft filter and cap, as far as I know...I last had it changed at NTB and I am not happy with their service but that is another story... I will check the oil cap first Then air check at the ICP and hope it's not the HPOP itself...
No, I don't know if my ICP is low for sure...however I do know that I want to get an AE scanner...I've already spent 90 bucks at the dealer on testing so I figure if I am going to have to do too much testing it'll pay for itself quick! I am going to look for the testing of the ICP with a volt meter however that I can do.
I found out that my Bullydog PMT shows ICP so I hooked it straight to the battery so it would show a display while I cranked the engine. I cranked it cold and my ICP started at 0 and climbed to 500...started...and kept going. Then I drove around quite a bit and parked it at home and immediately tried to start it and it wouldn't go higher than 300 Now that I know I have a leak does it sound like it could still be my STC Connector...or do you think it's in the oil system past the pump...
I can't do an air pressure test until Wednesday... Any thoughts are greatly appreciated!
Hopefully any of this helps the original poster as well!
I dont even command the IPR shut when air testing at work with the IDS, and never had a problem finding the leak. Ford does recommend that you do close the IPR and no longer then I think 1 or 2 mins at a time or you can ruin the valve. I have pumps cause the same issue but if you have down time it would def be worth your time to pull the turbo and the HPOP cover and check the STC fitting and maybe even your dummy plugs on the HP oil rails.
Yeah I am going to take the time Wednesday to tear into it...I have already replaced the stc I hope its not leaking there. So the air test works with the ipr open or closed? How do you apply 12v what is the polarity or does it matter? Thanks again for the help!
If you dont close the IPR you will hear a bit of an air leak but then again I know what im listening for(not to sound arrogant). Generally ive found that if you hook up and air pressure test it and when you release the air chuck and it spits oil back at you, that you dont have a leak and have a pump issue. As for the polarity im not quite sure off the top of my head.
Polarity doesn't matter on the IPR, as long as you don't short it out.
What does matter is not applying a full 12 volts to your IPR for more than 60 seconds at a time, then letting it "rest" for 30 seconds.
Well I pulled the dummy plug on the passenger side and the lower o-ring was demolished. I replaced the dummy plug with the new "updated" version and while I was in that side I also replaced the stand pipe. I took it down the highway and brought it home, my oil temp was around 195 I turned the truck off and waited a second she started right up. Turned it off, waited 5 minutes...she started right up. Waited another 10 minutes and she started right up....It turned out better than I could of expected! Thank you all for your help
