I'm in the process of trouble shooting milky oil in the hull of a 03 GTX LTD I thought It to be a good idea to post my known area's of leakage and have other members contribute as well in an attempt to help others with a similar issue.
My known problematic areas are:
BB and Bellows
Oil cooler (Due to excessive corrosion)
Front Main Seal (behind engine mount bracket)
Torx plug o-ring for Block Bolts
Front oil pump housing (Salt water sits in a nook on top of the housing and eats its way past the seal)
