How about this one.
1. How can you tell if the intake gasket has been replaced or not.
a. Is the gasket different than the OEM?
b. Do GM use silicon around the intake to insure to leaks.
Thanks.

1. LOOK..take a look at the intake..are there witness marks on the bolts?
Are there areas around where the manifold bolts to the head that are cleaner then the rest of the engine?
a. the gasket has gone thru a few revisions over the years..I believe the new factory gasket is black with metal "plugs" next to the bolt holes
b.I don't quite understand this one, but..GM recommends that a bead of sealer go across the engine block between the heads. I just put a small drop on the head itself to seal the corner where the gasket meets the block.....GM gray silicone or Permatex gray silicone sealers work the best IMHO
Most importantly, the bolt threads need to be cleaned and a small amount of blue loctite is to be applied to the threads when the bolt is installed...torque the bolts to 11ft/lbs
