Driving south on I-5. Heard loud rattling noise which became loud banging noise, followed by boom and white smoke pouring out from under the hood.

After engine has warmed up, there is a constant enging/tapping/rattle noise similar to the sound that bad lifters make. This sound is prevalent under all conditions and more pronounced on acceleration. I brought it to the dealership several times and they indicated it was a normal sound per detroit. Detroit has a document id#843248 that addresses this problem. I complained to gm and they have extended the warranty on the engine to 100,000 miles or 11/27/07 whichever comes first. I am still not satisfied as the noise is consistent and an irritant. I have looked at your site for other similar complaints and do not see any. There must be a mechanical fix to this problem but it is being ignored. The engine sound has increased since it was first noticed indecember, 2002 and reported to the dealership.
