TSB for LIM gasket

[AaronGTR]

There was a new TSB realeased on march 4th for the lower intake manifold gasket. It seems GM designed a new gasket to cure the common leaking problems with this part. They've been replacing a dozen a week on alero's at my dad's dealership. Anyone with re-occuring leaks or lots of power mods should get this replaced. Just make sure they have the new gasket.

A new design intake gasket, P/N 89017279, has been released for service on the 3.1 and 3.4 engines and is currently available from GMSPO. The material used in the gasket has been changed in order to improve the sealing qualities of the gasket. The instruction sheet sent with the gaskets advises the technicians to replace the intake bolts with new ones that have a thread locker adhesive added. Currently the new bolts are unavailable from SPO. In the interim, the technicians are to clean the existing bolts and then apply a thread locking adhesive, P/N 12345382, and tighten to a new torque specification.

The new torque specification is a 2-step process; tighten the vertical lower intake manifold bolts (the four middle ones) to 7 N·m (62 lb in). Tighten the diagonal lower intake manifold bolts (two on each end) to 7 N·m (62 lb in). Tighten the vertical lower intake manifold bolts (the four middle ones) to 13 N·m (115 lb in). Tighten the diagonal lower intake manifold bolts (two on each end) to 25 N·m (18 lb ft).

The new torque specifications will be reflected in Thursday's down load of SI.

So it would be better to wait until the new bolts are available to buy the new kit, right?
