Unique Part, Snow Job, or Bad Luck?
 

I have an 03' Lightning. I had to take it to the dealership for the first time today. After 9 hours, they called me to say they had to keep the truck overnight because they didn't have a valve cover gasket which fit my truck. I don't believe the gasket to be Lightning unique. Is it? Are they snowing me? Would a dealership run out of valve cover gaskets for their 5.4 liters?

The valve cover gaskets are all the same, but there are two different versions of the heads. There is an 11 bolt and a 13 bolt. All the Lightnings as far as I know use the 13 bolt valve cover gasket. Sounds a little fishy to me...

It was a snow job. They didn't even replace the gasket. I guess keeping it overnight was pay back for me being particular about my vehicle.
