Here is member brad arthur's nickle coated timing cover after eating 3 sets of gears. We found the height of the distributor gear to be wrong (not a cover defect) Normally one sets of roached gears will eat the oil pump up to the point of very low efficiency. The nickel not only protected the pump but the pump is still in spec after the nickel was chewed away and that is only a small amount but their is still sufficient nickel left over to give the pump many times longer service life than pumps without the nickel coating. Here is the proof
and here we see the oil filter adaptor with cosmetic scratching and a very small amount of nickle worn out, the nickel is just worn on the surface of the stock grooves and will still protect the pump for may many years.
