Walked out to my 300SE and noticed a puddle of water under it. However, it wasn't something easy like a hose, it was dripping down the oil pan. Here is a picture of the depressing sight.



I'm guessing it's the weep hole, can't see any coolant from above. How long do I have before the bearings eventually seize?

If I do have to replace the water pump, I'll probably do it myself. But reading a lot of the posts on the m103 water pump is scaring the crap out of me. Looks pretty hard.
