re: autofarm's silsleeve liners: I noticed they used nikasil.
Nikasil was what the old jaguar v8's had (pre 2000) and what the failed BMW v-8s had before they started using a different substance. The jaguar motors were good to about 40-50k miles.
As I understand it, the nikasil was attaked by the higer sulphur fuels found in the US. But I believe we use lower sulphur fuels now so it shouldn't be a problem. Interesting reading if you google nikasil with bmw or jaguar. Lots of engine failures credited to that stuff, but it may not be an issue now if we don't have sulphur in the fuel anymore.
