blackish green sludge?

[mtchockey30]

Hey guys went out to my truck (2005 F-250 diesel 115xxx miles) today and pulled out of the garage and noticed some blackish green sludge that had overflown from the coolant reservoir. I was told 2 months ago "I'm was starting to get the 6.0 problem". Im guessing this is oil in the coolant?? So what does this mean I need to do? How and what do I need to do to fix the "6.0 problem"? Thanks

Just FYI if you didn't already figure
if it is oil in the coolant you don't want to be driving it until resolved

I put it up!

cool

besides doing the oil cooler / egr delete/cooler etc and any updates to the new improved stuff

you will need a full flush with the ford chemicals to get any oil out of the system IMHO

the ford vc-9 is really more for scale and/or rust deposits. for oil, i'd recommend running simple green through the cooling system with a hollowed thermostat.
also, when you go to drain the system initially, remove the coolant reservoir first. since the oil will tend to rise. if you just drain it, the oil will coat the entire system as it drains.
that's if it hasn't turned to chocolate soft serve yet

Green? What coolant are you running? Dont know of a green colored diesel coolant
