    Well I was replacing my steering stabilizer shock today and saw a small puddle of oil just under the oil filter. I looked up and and the freeze plug on the oil adapter was soaked with oil and looks to be dripping off that. The cooler lines felt dry above and can't see what else could be leaking in that area. The dealer told me the freeze plug rarely ever leaks. The seal for the oil plug adapter looks dry as well. Anybody ever have this problem? My truck is an 02 2500hd Chevy. Is it a b!tch to replace the whole oil adapter assembly and cooler lines? I assume an oil change needs to be done as well...

    Thanks for any feedback guys!

    Yeah the oil cooler lines just plain suck. Need to unbolt the drivers side motor mount and raise the motor some to get them in or out. Took forever for me to do the ones on my 2000 with the 6.0

    The lines feel dry as so does the seal. The only thing thats soaked with oil is the freeze plug on the side. The dealer swears thats not the leak as they never leak. Is there anything else above the area that could be leaking down? I just don't want to start ripping out the cooler lines if thats not the problem...thanks again!

    There is a rear main seal cover that can leak and run down that way. Had my rear main and that cover gasket replaced this summer. But you gotta pull the trans/transfer case out to do them.

    Thanks guys. Just picked up a dorman replacement at Advance Auto. $51 vs. $125 at Spitzer Chevy. Looked again underneath and everything is dry as a bone except for the freeze plug. I assume the seal went bad...
