That's a first. Did you have the oil changed by someone other than yourself recently by chance? I haven't seen a dipstick tube leak on these cars yet. I have seen the back edge of the timing cover sweat near the top rear on a bunch of engines but never enough to actually drip or run down the block. Will post pics later, I have a couple of engines on the floor.
Can you post pics?
