mfewtrail Posted August 23, 2010 Report Share Posted August 23, 2010 1990 3.1: Lower intake manifold bolts - tighten to 15ft-lbs in sequence, then tighten them to 24 ft-lbs. Upper intake manifold - 16 ft-lbs, there is no sequence for these. Rocker arm studs - 47 ft-lbs Rocker arm nuts - 18 ft-lbs Rocker cover/valve cover bolts(just in case you want to torque those too) 89in-lbs(note this is in inch-lbs!) Here's a picture for the lower intake manifold torque sequence: http://home.windstream.net/mfewtrail/images/intman.jpg Quote Link to comment Share on other sites More sharing options...
