Truck even though it is a ’97 has only 84K miles on it. Started rad R&R by draining the coolant, Hmmm kinda dark but still recognizable as antifreeze. Pulled the upper hose off and yee haaa! Liquid oil there! Had pooled inside the hose. So I am fretting over pulling the heads but now I am curious to say the least. Checked the dipstick and no water there no milkshake oily stuff, just oil. So far have pulled drivers side plugs as they are the easiest to get to , and all look perfect for age and run time. So, the big question from me, is where the heck does oil actually get into the coolant system ? Since it is pressurized system oil has to be pressurized to get into it? Or does it get drawn in somewhere when coolant cools down and sucks it in? Does coolant leak into a cylinder and get back to rad from combustion chamber? Not much oil there. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So somebody or all of ya educate me.
