Hello, I have a 2010 F150. Last month I changed the fluid, filter, and pan on my truck. There has been no leaks for a month. Recently went away for a weekend on a snowboarding trip so my truck sat for 3 day without moving. The temp get down in the low 20s. When I came home there was a decent size puddle underneath the truck. It looks like it was leaking from the rear area of the pan. I went around and checked to make sure all bolts were still tight but did not find any loose. Any thoughts?

 

Did you reuse the pan gasket or use the cheap cork one that came with the filter?

 

I had purchased a new gasket from Ford. Gasket was make out of metal with a rubber line on it for sealing
