School Me On The Nikasil Problem

[wishihad50k]

I'd at least do compression on the engine and/or leak down. Current sulfur content in gasoline sold in the US is between 15 to 50 ppm, as opposed to at least 350 ppm in the 90's. If the car do not have a problem now, it will likely not have a problem due to Nikasil.

Leak down? So can I assume that if the compression is great, that the Nikasil lining is still good? What range should I look for when doing a compression test?

May I suggest that you do a search.

175 psi to 200 psi with less than 10% variation across cylinders. Nikasil casting # below.
