At least you made it another 6 months.
Since you are going so far as to replace the valley pan, I strongly recommend you do the coolant transfer pipe that is under the valley pan at the same time! Just did mine and isn't too difficult and love the piece of mind. I used the All German Auto (AGA) expandable pipe. A bit more expensive than the Uro and another copy, but very well made. I highly doubt I'll have to replace this again.
