Have a 2010 F250 heavy duty was told that the 2010 6.4 was different from the previous years is this correct

 

Yes, it's true. All trucks built in 2007 and later must comply with new EPA regs. To do so they use DPF (diesel particulate filter) technology. Briefly stated the DPF is a large filter in the exhaust. You can see it under the passenger seat on your truck. As the trucxk runs the DPF captures the soot that used to come out the tail pipe as black smoke.

When the filter gets full enough, a sensor signals the computer and the computer causes the engine to inject diesel fuel into the exhaust pipe and the DPF on the engine exhaust stroke. Doing so causes a very hot fire in the DPF which burns the soot and sends it out the tail pipe as ash.

Simple enough right. Stay on thios forum and read threads on DPF or DPF delete or regen (thats the common name for the act of cleaning the DPF) Enjoy, and welcome to the forum. Hang here and you will learn a lot about your truck.

 

Thanks for the information. Nice Forum

 

Do you mean different than 2008 - 2009 ?

 

Yes is the engine the same

 

All 6.4's are the same.There were EGR valve updates, head gasket changes, etc, but nothing that would make it a different engine.
