#1 - If my knocking Vortec engine is considered "NORMAL", are the exact same engines that don't knock considered "ABNORMAL"? If so, it sounds like the consumers that got "ABNORMAL" engines sure got lucky.

#2 - I have only one knocking cylinder in my Vortec Engine. Are the other seven cylinders in my engine "ABNORMAL"? If so, I guess I should be happy I didn't get more "NORMAL" cylinders in my engine.

#3 - Since "NORMAL" is "CAN BE EXPECTED", what in the world does "CAN BE EXPECTED" have to do with "DOESN'T NEED REPAIR"?
 

#4 - Why does your GM TSB# 01-06-01-005 illustrate the internal engine damage that a "COLD START TICKING SOUND" may cause on your 3.1 Liter 2000-2001 engine? This is even though it says it is "NORMAL" and causes "NO DURABILITY OR LONGEVITY ISSUES" just like your other TSB's on the V8 Vortec "Cold Start Knock" engines do.

#5 - Since "NORMAL" is defined as "CAN BE EXPECTED", how many vehicles would GM be able to sell if they told all potential consumers they could "EXPECT" to have a slapping/knocking engine that may requires 3.5 quarts of oil between oil changes during warranty while it is new (0-36K miles)?
