are 6.0's reliable if you keep them stock?

i'm looking for my first diesel, and i found an 03 6.0 for dirt cheap, new injectors, new ficm, but its all stock. if i didn't chip it or just ran a mild tune, would it be pretty reliable without studs and such? if i did exhaust, intake and an egr delete would it be fairly reliable or what else would i need to do to make it a daily driver?

Re: are 6.0's reliable if you keep them stock?

For the most part....yes. Heads have been known to lift on stock trucks. Stay on top of maintenance, stay on the mild side of tuning, and yes it'll be plenty reliable. That one already has new injectors and FICM, so you'd be ahead of the game a good bit. EGR delete is a must if emissions allows it. Intake isn't really necessary on a 6.0 as the stock filter can handle up to about 500hp. Exhaust will help lower EGT's for towing. I'd add a coolant filter and the blue spring upgrade (stiffer spring in the fuel pressure regulator...raises/maintains good fuel pressure).

Keep the oil changed at regular intervals, new fuel filters every other oil change (Motorcraft filters ONLY), don't flog the piss out of it daily, and she'll gives you years of service.

Re: are 6.0's reliable if you keep them stock?

Yea really. Google "blue spring 6.0". Probably thousands of threads on it.

Basically it's a stiffer spring that goes in your fuel pressure regulator (on the filter housing under the hood) that raises/maintains your fuel pressure. The stiffer spring is blue, hence the name. Factory updated part. Just cheap insurance for happy injectors. Cost about $65, takes less than an hour to install.

Def go with blue spring like the guys are saying and don't get a cheap one heard stories of people getting ones that aren't working properly. I would also throw on the 6.4 banjo bolts. I run my excursion with all of this on stock head bolts with Drews Economy tune it's plenty of power and torque for me as a daily driver and towing my boat and safe so far.

Have your FICM voltage checked at startup. Even if it's new your charging system may not be supplying enough power at startup and the stock alternator is IMO not even close to the task. If your voltage drops too much you'll kill that new FICM in short order.

Good time to throw in a new thermostat too.
