6.0 WONT GO
I have a 6.0L in a 2005 f450. The truck has a 1000 gal avgas tank and is used on the airport to refuel aircraft. Last week it would not start. Ford has had it for 7 days and so far it has been the coils then injectors then oil senders... Now they are telling me its has bad compression on all cylinders. The estimate is $22k for a new engine. The truck has 9000 miles on it and just under 1900 hours it idols a lot and never goes off the airport. The truck has had MAJOR computer issues since new and spent the better part of a month in the shop while under warranty sorting out that problem so i'm skeptical of the diagnosis.
1 What are the chances the engine is shot
2 Can it be reliably rebuilt
3 any advice would be appreciated
Thanks

<p><p>First of all you need some gauges like scan gauge II, there are a number of things on these trucks that will make them not run. How was the maintenance schedule on this truck? In a service environment where they idle a lot they need to be serviced on hours run not the miles and they do not like to be idled all the time, they are like a thoroughbred horse they need to be taken out and run once in a while. Without the gauges it will be hard to point you in the right direction. And crash is right a new soldier should set you back around 13000.</p>

We ran the codes and it indicated 3 of the glow plugs were bad then it had a clogged oil port in the filter so no pressure was indicated but it had oil pressure, once that was fixed they said the batteries were not turning the starter fast enough so new Batteries then a new starter I'm 3k into it with no better results than my Maintenance dept first look at it.
Oil changed every 3 months since new we are moving it to an independent repair shop the dealer is getting on my nerves We have 8 ford's all Diesels this one has been a problem since day one.

Oil Changes
I reviewed the Maintenance Logs last night
2005 2 oil Changes
2006 3
2007 2
2008 3
2009 2
2010 3
2011 2
2012 2
So not exactly every 3 months as our PM plan indicates but 19x in 7 years should suffice but now ford is saying we failed to properly maintain the engine and that is the reason for the "failure" its being towed as I type to an independent Diesel Mechanic. Hopefully better news will follow.

Ok so I think this is the final answer... we were servicing the truck often enough but we were using non motorcraft filters apparently that caused the oil flow in the bottom of the engine to be less than in the top of the engine causing scoring on the rods and crank as well as the cylinders. Not sure if that is all true but we did test the truck at the shop and it does have less that 100 psi? on each cylinder and the lower end is shot. The new engine is 13k not 22 that was for a 6.7 he quoted us the wrong engine. I hope we can get another 10 years out of her now.
Thanks for the help.

I would be very interested to hear how this engine actually sounds cranking over, if it does have less than 100 psi in all eight cylinders. I'd also be interested to hear how fast it's cranking over.
