It is either engine oil or transmission oil if pink or red from the transmission cooler in the radiator. If it is the transmission, catch it early and you can get by with only a transmission flush and a new radiator.
Thanks guys, could this also cause some pinging I have, in OD, mostly, and also could it cause any oil in my air intake tube going to the Throttle Body assembly?
Thanks again
More than likely the pinging caused the blown head gasket not the other way around. Pinging is detonation and detonation breaks parts, you're lucky it's only a headgasket. Pull the plugs and check for water/oil on them, usually only one side will go bad but I'd replace both to be on the safe side. While the heads are of clean the combustion chambers and the piston top to get rid of any carbon deposits since that's what most likeky caused the detonation in the first place.
