I need to find a diagram for the exhaust manifold for a 1998 GMC Sierra.?
5.7 liter 4 wheel drive automatic. Exhaust manifold came off easy, however when we went to put it back on none of the holes would line up. Any help would be greatly appreciated. Yes, I do think that it is warped.

all gmc & chevrolet small block exhaust manifold,s are the same .....as far as manifold mounting.....if there have not been cylinder head change,s they should go back on as they came off......warpage would offset the mounting hole,s slightly......unless it is a very severe case.....this is usually caused by overheating....in which case manifold,s should be checked closely for crack,s due to metal crystalisation....new manifold,s may be in order...good luck!
