I'm willing to bet it's the oil pan. New gaskets or [size=+3]stop leak[/size] should fix her righ up
Ummm...no, bad advice there dude...stop leak doesn't "fix" anything...New gaskets and/or seals fix leaks...

Rear main? Get under it with carb cleaner and clean it all off and add some UV dye to the oil then get under it with a blacklight after u notice the leak.
That right there is a very good suggestion IMO because I know my 16 year old truck that's had a small leak for a LONG time...There aint too much cleaning that can be done under there. Where do you get the UV dye? I too have a leak, obviously, that I believe is the oil pan.
gmcyukondriver, you likely don't have the cooler...It's a possibility of course but more than likely you don't. I would say your best bet is to get under there and check out the block like they said....No oil there it's pretty certain it's your oil pan which I would have to say is a pretty common leak on these trucks, especially if that engines been in a while...Take some pics even while you're under, then I would say if you can't come to a conclusion there, then I would use the dye like I plan to do. I'm almost positive it's my oil pan gasket but just to be safe I'd like to try the stuff out. Also I know you said your oil drain plug is leaking correct? I noticed mine has some oil around it too. I wish it was just that drain plug and that simple but hope that helps.
Next step, say it is your oil pan gasket...being 2wd I believe you may have some issues with the actual oil pan clearing and coming off under there. I know stock 4x4 guys have actually had to lift their engine to get it because the front diff is in the way, but I'm not sure about for you 2wd dudes. Anyway, I've been told with my lift since the diff is dropped I can clear but who really knows. Obviously it shouldn't be too hard to remove pan bolts but dropping it may be the issue so check on that.
We had the UV dye at the dealership but you might be able to pick it up elsewhere...as for the oil cooler lines I would think you have those since you have the tow package but idk...and as for changing the oil pan gasket it isn't too bad to change if its setup like my 96 2wd with a 5.7L and automatic you would just unbolt the oil pan and slide out the old gasket and reverse the process
Oh yeah I didn't even think about that. You could just unbolt it enough to slide out the old gasket, BUT are there any tricks to sliding the new gasket in and making sure it's lined up right? Yall won't believe this but I had my engine put in by a shady mechanic (his engine) and the oil pan gasket is on the OUTSIDE!!!! hahaha It's a solid engine for sure but I found that freaking hilarious. Real testament to his or his employees mechanical knowledge.
This is why I'm 100% positive it's my oil pan leaking
Stop leak won't do it. Go to a dollar around you and buy oven cleaner spray the engine then take it to the car wash. Check valve cover bolts even oil pan bolts maybe there just lose it won't hurt to check.
