Ok gang here it goes. I just purchased a used 2004 F350 with 6.0 and automatic. Used to have an old 6.9 diesel F350 and I am amazed that some of the items have not changed much body wise it would seem lol.

anyway, this poor truck I bought cheaply, but it was a Ford buyback...I have the documentation of everything that was replaced by Ford. I could list here if that would help. But I would really love for those of you that have been longtime owners to give me some hints and suggestions of things to check and look for so that I can hopefully not have future issues or at least not as many !!

thanks for any help offered

Did you get maint documents for it? If not I would suggest changing all fluids so you have a good baseline to start your maint schedule with. Congrats on the new truck.

Hey Furyxxx,

I'm new to the forum but not to the 6.0 Power Stroke.

The first thing I learned about the 6.0, is that the EGR will coke up with cabin and it will need to be cleaned or replaced. I've had to do it to my 2005 F250 (bought new 2005) at about 52000 mls.

The first sign that it's getting stopped up is, you'll fill a power loss and the turbo won't boost as fast. 6.0's are not noted for quick boost anyway but it will lagg even more than normal. Than you'll start to notice the fuel mpg drop off and the longer you go without cleaning the system the more fuel it will use and the weaker it will feel to you.

Very important to know is that the trany fluid is not the run of the mill type! Torque Shift trany's only take SP type fluid....anything else will damage the trany. There are two trany filters that need to be replaced every 50000 mls... sooner if you pull or haul alot with it. Main trany filter in the trans itself and a pre filter located in the return line. You most replace both of them to keep from having trany problems.

Simple way to help with the coking problem and increase torque is to replace stock air box with a cool air box and remove the cat-convertor and muffler. This will let the engine beathe and decrease coking and add more hp & tq.

As far as any other problem, I haven't had any. Knock on wood.

I hope that this has helped you some.

P.S. If you work in construction I would not advise a cool air box, because job sites are too dusty and dust will get through cool air boxes no matter the type!!!

Mark, thanks this is the kind of stuff, i wanted to know. From the list of repairs Ford made the turbo and the egr and head gasket where replaced already at about 30k miles. But yes i will check those items right away, dont want to get off to a bad start.

This is illegal in all 50 states. Its a violation of the Federal Clean Air Act.

The best way to keep your EGR working is to run the truck the way it was designed to be run. Don't use it for short hops, lots of start stop and in heavy slow traffic. DON'T IDLE ANY LONGER THAN YOU HAVE TOO! That's what gums up a EGR. Get it out & run it in the power band. When you start up in the morning, don't let it sit (especially if its cold). Get in, turn it on, let it stabilize for a minute or two, and then put it in gear & drive it. If work is only 5 minutes away, find a different route that takes 15 mins. Let it get to operating temp & burn off the acids that build up in cold engines. Let it run at 1.5 to 2k rpms to keep the batteries charged.

If you are going to tow heavy, a 4" CAT BACK exhaust is a good idea, as well as gauges (EGT, Fuel pressure, and trans temp). The dash gauges are 3 position idot lights (off, good, and shut it off). They won't move until you have a problem. An aftermarket intake is not necessary until you decide to replace the injectors, turbo & fuel system & make the truck a dragster or sled puller. A tuner will cause problems with the head gaskets. Your best bet is to keep it stock.
