I've had a few of my vipers spring a leak. Warranty will fix them.
The oil pan gasket usually leaks. This is where some of Chryslers enginering is a bit behind. GM cars were plaugued with leaks for many years until they designed a better oil pan gasket, and boy did they. The new oil pan gasket is a work of art, and never leaks, not to mention it's reusable. They also enginered a sealant, it's called the Right Stuff, under the Permatex name, that is space age quality. Really I think Federal Mogul, and the Permatex corps helped them with this, as they sell these products today.
As inovative and creative as Chry. are, they seem to be in the dark ages on many things. That oil leak in my 04 SRT cost them nearly a full day's labor to fix.
If the dealership is using a gasket sealant other than the above mentioned, I would request they use this, or supply it for them. You will never have another leak.
