I am getting ready to order some total seal rings for my 91 diablo and they need to know if my liners are nikasil coated. My book (which is for a later model) says that they are. A very knowlegable dealer and the lambo rep says they are not. any ideas

Yes, they are Nikasil coated.

To quote the Factory WSM directly:

Liners - The cylinder liners are steel alloy with aNikasil facing inside.This treatment ensures a very high surface hardness. This type of liner cannot be honed.

end of quote.

Do you know if they used this Nikasil coating in the 1984 2-valve 5 ltr. engine?
Just Curious, Thanks in advance. Sincerely Vic
