Diesel mechs good with 6.0L

[Smokin]

Does anyone know any diesel mechanics that are good with the 6.0L engine? I live in Woburn so I would prefer someone near me or within 30mins. I'm having some issues and I'd rather not send it to Ford. Thanks

Chad at massdiesel is the guru of the 6.0's

[Smokin]

Yeah MassDiesel was one of the places I was thinking of. Someone told me they were a little pricey though and I don't have a ton of money to spend on this thing. I might have to give them a call though

I think Chad finally got out of there a few weeks back. Sounds like everything was amicable and all but as best I know he doesn't work for Scott anymore. Not sure where he is going either though.

The new guy there I know is a good mechanic, but isn't quite as versed on the 6leakers like Chad, but I would certainly trust him with my truck. He just needs a little more experience to get as fast as Chad.

I think they can be a little pricey, but they do good work and stand by their work. My truck had pretty much the whole deal done there (studs, EGR, oil cooler, and even heads since they were cracked)

What are you needing done to the truck? Also Scott is definitely good at the communication part and will give you a straight answer if your looking to get a quote.

Well my situation is a little tricky. I just installed 175cc injectors and a Powermax turbo. After the install, I noticed that I'm getting some sort of surge or hesitation between 45-60mph that isn't turbo related. It also "chugs" in rapid succession at lower speeds after letting off the pedal. Now I've developed a new problem where it will have a hard time starting when the truck is warm. I checked the high pressure oil numbers and they seem fine. The only thing I found was that the camshaft position sensor and the crankshaft postion sensor aren't sync'ing with each other. I've spent hours trying to diagnose this thing but I'm ready to send it to someone with a little more experience.

[05lonestar]

Sounds like a tunr issue too. What tuner are you running in it?

[Smokin]

I'm running a SCT with custom tunes. I've tried two different tunes along with two different FICMs and I'm still having the same issues

[jdc753]

that was my first thought too was tuning. Did you get the tunes re-written for your new injectors and new turbo? Just might clear things up and getting it running smooth again.

If its not tuning I would be leaning towards some sort of possible leak in the high pressure oil, or maybe something with the turbo oil drain tube. Just wondering if maybe an o-ring for the injector or high pressure oil rail maybe got cut or knicked during reassembly and causing a little bit of a leak when the truck gets warm.

Yeah both tunes were written for the new injectors and turbo. They are from two different people so I'm thinking it's not the tunes. As far as a high pressure oil leak, I'm getting 640psi for both desired and actual ICP while cranking. The truck only needs 500psi to start. I even pulled the oil rails off to re-check them for any o-ring problems and everything looked good. The only other possibility would be a damaged injector o-ring. I was really careful putting them in so I'm not sure. I checked for combustion gases in the fuel and fuel in the oil and got neither. My truck is currently sitting in a parking lot right now because it wouldn't start this morning after I made a few stops. If I didn't have so much money into this truck it would be sitting at the bottom of the ocean right now. :smiley35:

[jdc753]

Dang sounds like you sure are on the right track with things, hopefully you can get it figured out for cheap though. 6.0's do seem to suck peoples wallets dry, I have the same feelings as you many times with my truck.


Another long shot I guess, but do you get smoke when you tried cranking it over this morning and it didn't start? I'm just wondering if the FICM might be acting up on your causing the no start condition. Not sure how much it would relate to the other symptoms though. I know when mine went out I had a code for the Cam and crank position sensors (low voltage)

[Smokin]

I haven't noticed any smoke coming from the tailpipe when I'm cranking it but I can't say that I've been looking either. It sounds like its not getting fuel and then sometimes it will attempt to start. I actually just went and tried the truck again and I did get it to eventually start. Both FICMs I tried had 48V so I don't know. I think I'll be calling MassDiesel tomorrow. Should have bought a Cummins...

[05lonestar]

Did you put the tuner back to stock and try starting it?

[Smokin]

Did you put the tuner back to stock and try starting it?

I just went out and tried that. Still didn't want to start. For some reason the camshaft sensor and the crankshaft sensor won't sync with each other. I'm guessing that is the reason it's not starting. I was reading somewhere that it could be a chaffed wire but that's like finding a needle in a haystack

[05lonestar]

Could be the crank sensor also.

[95Cummins]

A friend of mine has a 6.0 and he had a pretty similar situation. No major mods, but his would chug and stuff. Ended up needing a cam sensor and the pigtail for it, he said the wiring got chafed at the end.

Just something to think about :m2c: :HoleShotHolset:

[massdiesel]

Can I ask how did you check to see if their was any combustion in fuel????Also did you check for any codes? Check fuel psi??? Did you air check the high pressure oil system for a leak??? Sounds like a hp oil leak where it wouldnt start hot.Give me a call and I can help you out no problem!!!! 05-06 have engine harness issues as well!!!!

[Tooned]

these trucks can really test a persons patience, my dad has been a powerstroke tech for 8 years or so and there are some trucks that will still get under his skin. he and i work together now and ive learned alot from him in the last 2 years. the most important part of working on or diagnosing a 6.0 or even 7.3 for that matter is having the right tools and the know how.

[Big John]

My Mechanic says replace the crank ensor and descale the side of the block.

[CT SMOKER]

Had same prob on a friends truck put a cam sensor in it. if u have small hands u can get sensor out from bottom with no dissasembly a guy from the top with a long screwdriver can release the lock while u pull on connector from bottom helps a ton its a very tight fit but it does work.if u want pm me,i havent had a 6.0 chuggin prob yet but quiet a few 7.3 the sensor i belive is a IAC have seen thoes cause that and if u have over oiled your air filter seen many times will mess up map sensor a can of electrical cleaner and gently clean it might be a good start also to the chuggin issue

Update: I replaced the fuel pressure regulator and tightened up a loose battery connection and the truck seems to be starting fine now. Very strange seeing that I was getting about 55psi for fuel pressure before and the truck would turn over with plenty of power from the batteries. I still have the other issues and it will be going to MassDiesel next week.
Combustion in fuel -- I was told you can unplug the fuel pump, remove the top fuel bowl cover, crank the truck and watch for tiny bubbles to come out of the fuel port. I was also read that you can disconnect each fuel line going to the heads, tie a balloon to the ends and see if you get any pulsating in them as you crank it. This is called the Compression Bubble test and a whole write up can be found here -- http://www.forddoctorsdts.com/articles/article-08-03.php
I figured you guys would know this little trick lol.
No codes other than crank sensor output. That was only when it wouldn't start and the batteries would get low.
HPO leak-- As stated, I was able to achieve mid-600s for both desired and actual Injector Control Pressure. If there were a leak I would assume the actual number would be lower. 520psi is required to start

yeah the cam sensor was the first thing I tried but that wasn't it. I guess the crank sensor is a PITA to get at so I wasn't tearing everything apart unless I knew it was definitely that.

I definitely agree. I've had this truck for about 2.5 years and it's my first diesel. I didn't know anything about them at first but I've spent a ton of time researching the 6.0 over at Powerstroke.org and a few of the other forums. I got the Auto Enginuity program too and it has been very helpful in diagnosing problems. I'm still learning about it though...they can get pretty complicated with all the computers and sensors that rely on each other. Sometimes your just better off sending it to someone who fixes them for a living.

Advanced automotive performance in uxbridge is real good with diesels, they work on powerstrokes all the time. Just to let you know.

[CT SMOKER]

If that's the sensor behind the powersteering pump u don't have to take everything apart it will come out if u have small hands

[Smokin]

The camshaft position sensor is behind the power steering pump. The crankshaft position sensor is behind the A/C condenser
