Does anyone know of a site or literature that addresses the Nikosil engine issue. Reports on this forum and elsewhere point to high failure rate of XK8 engines similar to the problem BMW had with its 1993-1995 V8s; BMW ended up replacing 1000s of motors. Considering the cost of a used XK8, info on the Nikosil issue would be helpful to prospective owners as well as current owners who may be facing engine replacement as their cars approach 80k miles. Thanks for any input.
