Add me to the list of leaking PTUs (07 MKX). Incredible Ford’s been silent, I’m guessing a class action would be needed to get a response.
Likely trading in the car in less than a year. Haven’t had any symptoms except black sludge on the PTU. Should I bother flushing the fluid? If chances are very low of a catastrophic failure I’d rather forego.
Also should that stop the leak, or even with new oil will it continue leaking? It’s black sludge so I assume it’s splatter from the vent, not the seals.
