I have recently noticed a leak that is coming from the rear passenger side of the motor. At first I thought it was oil, but after comparing the leak droppings and oil from dipstick on a piece of paper I have decided its water and likely antifreeze. Its not green like the antifreeze in my radiator and it has a slightly oily feel. The leak appears to be coming from around or above the starter and dripping down to the transmission bell. Any ideas on this? I cant seem to find exactly where its coming from. I will attach a couple of pictures. Its a 99 suburban 4x4 with a 5.7 motor. As always, thanks for the info guys!
