Welcome.
Go check out the Sasquatch threads in the CRD forum down below.
There is a particular thread about installing the EGR delete package, with pix of the crud build up in the induction system near the mixing tube and valve assembly.
That area and down stream at the entrance into the intake manifold (flow control valve elbow) is clogged with oil/soot, and serious crud.
You don't want BG to dissolve that into chunks that break free and either obstruct your valves or wedge them open.
Better you at least try to chip that stuff out and vacuum out what you can rather than let it chunk up.
When I installed mine - I was able to reach in and rake it out where I could actually feel when I got to the edge of the mung.
From what I've read here and other diesel forums - after you get rid of the EGR, the carbon isn't there to gum up with the oil, and the oil just flows on thru.
The Provent will help there, so the oil that doesn't get trapped in the intercooler, and CAC hoses.
OTOH, there are those that make a case for the oil adding lube properties to the fuel.
::shrugg:: I used to dump my oil from oil changes into my Dodge Diesel's fuel tank, so I'm kind of partial to that anyway.
