My 2001 mustang recently aquired an oil leak, coming from the right (passenger side) rear area of the head. Had local dealler look at it and the head gasket was seperated in the rear corners of the head. After doing some checking on the problem I was informed the the 4.6 & 5.4 both have head leak problems right rear on the trucks but not to many 4.6l in mustangs. Apparently the truck prob is covered under a bulletin but not the mustangs. My car has 34,000 miles on it and I had to pay the hefty bill to have this fixed. Which I feel is B.S. Has anyone else haad this problem or heard of any of this.??
