ok, word to the wise.... Don't change your oil til after you do the cooler..... Drain your coolant and remove your filter before you remove the cooler. You can get the cooler in and out without having to remove the exhaust manifold or jacking up the engine, you just have to unhook the steering shaft and move it outta the way, remove your drivers side tire and remove the splash shield. You can work it out from there. And make sure you pick up some assembly lube and don't be afraid to use it on the O rings and walls of the cooler. Grab a spare gallon of oil. After you put the cooler back in, put in the oil an dspin the old filter back in. You wanna run the engine with just water and the old oil in it for atleast an hour. That will flus out the assembly lube from the cooler oil and coolant side. You don't want that crap contaminating your fresh oil.

I would just drop a 6.9 in it but the problem is this is my only truck....got it for a good deal so I though I'd just get new head gaskets and be back on the road with it...not the case had a lot more to do and now time with it is running out, going to be out of high school in a few and I need a truck now so I can get my career going in construction.....I'm not giving up on this truck yet...but if I find out there is any block damage that will call for a new engine That's the end of the line for me....just don't have the time.

So, you are confident that the goop is oil? Blackish gray and sticking to the inside of the rad doesn't sound like oil to me. Just suggesting that you make sure before you start on something you don't have to do. It has happened.

when oil goes though the paces of your cooling system, thats kinda what happens. thats the exact case for my system. the oil cooler is a good place to start. $43 bucks in O rings and gaskets, then see how it goes. if its still happening then go to the next possibility from there.

OK, because I have read this thread over several times and I haven't seen the OP'er confirm that it is oil. I would check the surge container for deposits and think about adding some water to the rad to overfill a little. Oil floats and will come over the top. Then you can run again and check again to see if the goop comes back. Just my two bits, which is less than $43 bucks and time spent.

dont get much closer to the top then right inside the radiator under the cap. you cant tell that its oil, it doesnt look like standard motor oil. looks like assembly lube. its got a consistency of lotion and the gray color of the lube. unless he sent it out to be tested then you cant tell if it is oil. and checking your overflow tank wont always help, especially in these cooler months. i know i almost never overflow into my tank.

Looks just like he said....got a thick layer of it coating the inside of the rad.
I'mma try and clean out the rad the best I can and fill it up with new fluid just so I can get it home and do more work.
