Soot buildup
I have been hearing some talk of soot build up with the 6.7's if they are not used to tow or at least run at hwy speeds on a regular basis, is this true for all of the engine's, or just a few? And what is the prognosis/cause and cure? Is this something that I am going to have to live with if and when I get rid of my 05 5.9 for a new one?
Also I have been doing some reading on Ford's new 6.7. They claim that by cooling the exhaust gases after they go through the EGR valve that this will not be a problem for them, any info on that? Thanks.
