Can't Start His Wank
Nikasil is not your friend.
The same protocols that apply to early Jaguar V8 cars apply to early BMW V8 cars - having one that's had the engine replaced is desirable.
Nikasil is a trademarked electrodeposited oleophilic nickel matrix silicon carbide coating for engine components, mainly piston engine cylinder liners. It was introduced by Mahle in 1967, initially developed to allow rotary engine apex seals (NSU Ro80 and C111) to work directly against the aluminum housing.
Ha. Take that piston engines. We got our revenge.
