Thanks for the info. I just did a Google search and also found the following lot #'s of WLR's other people have had leakage problems with in the last year or two:

DHL766G
CLL555G
DFL717G
GEL 250G
GDL 225G

I'm working on the tail end of a 2010 batch that has been fine, but have a couple of 2013 bricks that will be needed soon. Neither matches your serial# or any of the above.
