Hi guys, I’m in So Cal and the trucks are a little pricey here.. I managed to find an 06 one owner F350 super duty Lariet Dually crew cab with 128k for 17.9k... the truck looks beautiful the inside and paint are like new.. the truck runs and shifts great but I noticed when starting it cold after letting the glows heat up it cranked for about ten seconds before it fired... after it warmed up it seemed to start a bit faster but it definitely took a few seconds of cranking.. now they didn’t want to budge on price and I’ve been grinding them and I got them to go about a grand less and I’m here now trying to decide what to do.. I’ve seen that this could be a leaky STC fitting but from what I hear this fitting requires the motor to be opened up to fix and is a lot of labor. Is this true? Could it be anything else? How much money could I be looking at to pay someone to fix this? I’ll be tapped out after buying this for a while if I do.. any help would be highly appreciated!

Walk away. Unless you have a strong need for THAT specific truck walk away. If you're set on buying a 6.0 get a scan tool (torque app with Bluetooth adapter, scanguage, etc...) to check engine parameters while you shop, this can help narrow down an HPOP issue from a low voltage issue. If you're already doing that then I apologize for wasting your time.

Also, it seems that prices for these trucks are all over the place these days and unless the cost of the used truck, plus whatever the cost to rebuild is equals less than the cost of a newer vehicle - even a gas version - then I don't see much point in buying the old diesel. I happen to find my Ex at the intersection of those prices so I took the gamble, so far so good, but I stash cash away when able just in case...

Well I actually just bought it right now because I was able to grind them down another grand... this truck is really like new.. literally the interior looks like brand new drivers seat included and the exterior is very nice too.. not to mention the CarFax shows it was one owner and they always serviced it on time and at the dealer... compared to the junk everywhere else I felt even if I had to spend a couple grand on an HPOP it would still be a nice truck.. that being said what’s the best way to figure this out? Which scanner is best? Thanks again!

I just ordered a Scangauge 2 on Amazon, it will be here tomorrow. There were reviews specifically saying how great it was for the Powerstroke 6.0 so hopefully it proves to be a good buy... I just bought a 2019 Jayco Eagle trailer and needed a truck to be able to tow it.. after buying a $60,000 trailer I really didn’t want to go spend more than that on a new diesel... I was looking at higher mileage trucks but I was finding trucks from 04-05 with over 200k miles for 14k or so... so for three grand more I got a beautiful one owner truck with half the miles.

Well congrats then! If you can, return the scanguage. Get a Bluetooth or wifi ODBII puck and use an old smartphone or tablet with something like torque pro and forscan. Torque is for guages and forscan is for codes and basic diagnostics (the laptop version requires a USB odb device but is more robust).

Sorry, OBDii device not ODBii. I had the scanguage2 but it's overpriced when compared to the app versions of scanner, especially if you have an old cellphone just lying around. For the long crank and/or no start, Google around a little and you'll find checklists for what to check. Also get a good shop manual. Diagnostic step one may be try unplugging the ICP sensor and see if it starts better. Beyond that you may need to do an airtest to pinpoint a high pressure oil leak.

Did the owner update the stand pipes and dummy plugs?

And I feel you on the overall truck cost, I got rid of a 2015 ram 2500 and got an 03 Excursion because of the 30k price gap! That, and hauling six people and two dogs in the crew cab was a bit tight!

The 05-07 HPOPs are very reliable. Don't change it out.

There is a lot to learn about troubleshooting a 6.0L! If you start guessing, it gets expensive.

Starting better when warm is more of a FICM (or injector) issue than an issue with the high pressure oil.

Get the ForScan app for a smartphone or a laptop. It requires an ELM327 adapter or a USB to OBDII cable for the laptop.

First thing to check is for codes. ForScan is a great code reader.

Also, you need to install a fuel pressure sensor and gauge ..... or at least have it checked. Low fuel pressure can seriously damage injectors and then they can trash the motor.

The type of coolant you run can cause expensive issues. You should first take your ForScan app and determine if your oil cooler is starting to plug up. You run the truck until it is COMPLETELY up to temperature (at least 15 minutes) and then pull the ACTUAL coolant and oil temperatures.

If the oil is more than 10 degrees hotter than the coolant, then the oil cooler is plugging up. It could fail and cause more issues.

Running hot, and running with bad injectors, are two of the more expensive issues that you can have. If you monitor the truck and pay attention to things, you can avoid big problems. If you think you can just drive it and not watch things, it will bite you and you will soon be posting that it is a POS.

Only thing I can really add to what Bismic said is to read, read, read. Learn as much as you can! Even if you can't turn a wrench, if you know what you're talking about when you bring it to a mechanic you'll save a lot of money and heartache. However, if you can turn a wrench with any decent amount of skill, you can work on these. These seem daunting at first, but once you start taking it apart you'll soon realize it's not so scary.

Thanks for the info guys! I don’t have an old smart phone lying around otherwise I would have bought a puck instead of the Scangauge 2.. I really appreciate all the info you guys have given me! I have been reading up on things but I will even more now. I definitely want to run a fuel pressure gauge right away.. what is the best gauge or way to do this?

Hey guys so the dealer had said the truck had been sitting for a while and maybe the voltage was low.. well driving the truck home last night took 45 minutes and I filled the tank which was empty and now it fires up cold or warm in about 3 seconds.

That's great, hopefully that was it! I've come to accept that I have an old phone hoarding problem, but sometimes it works out in my favor.

Haha well that’s definitely a benefit for an old phone! My scansgauge just got delivered from Amazon a couple minutes ago.. now I want to monitor fuel pressure... does the Scangauge do that or do I need to get a separate setup? Thanks!

For EGT and fuel pressure you'll need separate setups. Some of the aftermarket monitor/tuners have inputs for them or you can get something like gloshift guage pods. I went full nerd and programmed an Arduino Uno to read a 5v transducer for fuel.
