In the sticky helpful posts section is a link for replacing the lower intake manifold for a 99 GMC 4.3L. In the summary section is says to torque the bolts to 35 ft lbs. All the other guides and I saw and the one I used says 132 inch lbs which I thought equals 11 ft lbs. Is the GMC 4.3L different? Just having one of those "Did I screw up" moments.

Installation:

• Set new gaskets in place and apply silicone to flat areas on front and rear of engine block.
• Apply thread locking compound to manifold bolts.
• Install manifold and tighten bolts to 35 ft-lbs, in proper sequence.
• Install distributor.
• Install upper intake manifold.

 

DO NOT torque them to 32ftlbs. THIS POST has the proper information.

 

Good..I feel better now. What would happen if someone followed those instructions? Warped manifold?

 

If you don't snap off a bolt, you will most certainly over compress the gasket, compromising its integrity.
