Hey fellow mudders...
Last night when finishing up with the PHH (along with the fuel filter, thermostat/gasket and starter rebuild), i noticed some sludge buildup at the top of my radiator (see pic attached). Just trying to get an idea of how bad it is and whether i should be worried. The truck is going in for a coolant flush (with TOYO red) soon and was curious if that would fix the issue. Am i just being paranoid or is the amount built up typical? Thanks!

P.S. I have also attached some before/after shots of my PHH! To be honest, i think the fuel filter was more of a beeyotch to get off than that guy!

can't see. The sludge that people are usually talking about is a grayish clayish kind of material. Very good pic just posted a couple of days ago or so IIRC.
