I have a 1997 Jeep Grand Cherokee Limited 5.2L V-8, about 253K miles.  Used oil analysis is showing very high nickel (24 ppm in oil used for 3270 miles).  A previous test done 61k miles earlier was high but not critical (11 ppm in 2045 miles).  Both tests show very low levels of other wear metals, well in the normal range.  Does anybody know what parts in this engine may be coated with or plated with nickel that might be wearing out?
