On my pampered 2006 Liberty with 81,260 miles, I had a lot of oil leakage and took it to the shop to find and fix them. They found a 4-1/2" crack in the engine block on the driver's side under the air intake header just before the transmission connection flange.

Keith at Green Diesel said he had heard of about 10 instances of this and it appeared to be from poor quality casting, thin wall, porosity.

Has anyone else had this happen and gotten any support from Chrysler?
