03 Silverado leaky Intake

Anyone with a 2003 4.3L have an intake that leaks coolant around the bolts that hold the intake down?

I had my truck at the dealer twice for this problem and all they did was pull two intake bolts out and put a sealer on them and screw them back in. This lasted for about 1 month each time.

I never could get them to pull the intake off and check the seal or manifold for warpage or cracks.

It seems to me that the only way coolant could come up through the intake hold down bolts is if the manifold was cracked, warped or the seal was shot.

Now that its out of warranty they won't goodwill the work they performed on it even though I still have the same problem.

I'm just wondering how many 4.3's there are out there like this.
