" From: Frank Swygert <farna@xxxxxxxxxxx> " " [] " " That last of the 4.0L engines have a stamped steel valve cover. I " think 2000-06, but may have been after 2000. now i'll have to go out and look at my gf's '01... :^/ " Covers don't interchange except over certain range models this lines up with head p/n - " (87-90, #2686 [renix] " 91-96, #7120 " 97-99, #0630 " 00-06... #0331 " I think) due to differences in the way they bolt to the head. odd that they'd change this - but this is amc/jeep...

" " afaik no 4.0 heads have tin valve covers. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
