6.0 Powerstroke question

You may want to post this question at Powerstroke.org. There are a few For techs on there that could run a warranty service record check (OASIS report) for you.

Thanks for the feedback. It's a trade in at a Chevy Dealership. I couldn't find any service record in the truck.

The truck had been sitting for about four days so it was dead cold and it started within 3-5 seconds once I hit the starter. I was pretty suprised how quickly it started. The EGR cooler appears to be intact.

The no records thing concerns me.

Thanks!

Like Bedlam said, I would be concerned with the FICM if it had only been sitting for 4 days and needed a jump. Remember, the FICM's on these trucks have to convert battery voltage to 48 volts. Bad batteries are a real strain on them. I usually get 3-5 years out of my 6.0 batteries and they start getting weaker than I like. The cold start system on these trucks pull their power directly from the batteries for up to two minutes (depending on outside temp) before the alt is allowed to start charging.

Also, to be honest, my truck starts between 1-3 seconds. I hope you are just misjudging your time. If it takes 5 seconds there is more than likely a problem with the HPO system. The Computer will not fire the injectors until it reads a certain pressure which I believe is 600 psi minimum. It will crank for a certain amount of time and if it don't get the pressure it wants it will start closing the pressure regulator until it gets that pressure. This indicates a leak in the HPO system (more than likely the SCT fitting). If it is the OE fitting , it will get to where it won't start. If it is the updated fitting then it was not put in correctly.

If you have access to a ScanGauge, monitor FICM output voltage at cold start (low batteries are bad on this module). If the voltage is low, it will eventually fail resulting in a $300-900 repair or replacement.

My 2005 F250 XL Super Cab short bed 4wd PSD recently sold for quite a bit more but had only 110K miles and all the service records from only one original owner (me).

Looked at a 05 PSD with 185k miles

Motor starts great from cold without any misses or hiccups... No smoke boiling out of the tailpipe. Degas bottle looked clean and the coolant looked good. Truck ran good... Batteries were dead as it has been pretty cold so they had to be jumped off before I could start it. FICM concern there I suppose.

Drivers side TTY bolts had lines on them indicating that the driver side head had been removed and reinstalled at some point. These lines were not on the passenger side TTY bolts.

I have a decent understanding of these motors but I can't figure out why only one head would be pulled at some time. I thought if a 6.0 popped a HG you pulled both heads and did both at the same time.

Any idea why ford would have replaced just one HG?

Mostly just curious... I'm a gasser at heart but for $11,900 for a crew cab XLT F250 Short Bed 2wd... With a perfect body and interior...I'm at least curious...

Thanks!

I believe they are great motors when properly bullet proofed Jeremiah but I do believe I wouldn't touch it for more than 8-9000 unless they had a history or receipts to show what has been done. Does it still have the EGR and cooler? Has the HPOP been replaced with the new upgraded fitting? Oil cooler? Fuel pressure blue spring? If it has sit very long I would want to take the turbo off and clean it. This is JMO.

Like I said, I have one I drive daily and have been working on them (5 of them) since 2005 and they are good strong motors but need TLC to keep them in good running order.

When it fired off you said it run with no hiccups or misfires? The injectors are good if so. How many times did it take to start once it hit? Did it fire and run smooth the first time or take a couple cycles?
