A Member of my message board forwarded this information on a TSB to me-
Subject: Audible Spark Knock (detonation) TSB #02-06-04-023
(not only the LS1, but also 99-2002 Pickups and utility models with 4.8, 5.3, and 6.0L motors)
Condition: mild to severe engine ping (spark knock). worse on acceleration.
Cause: corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity
(another reason for not squirting your motor down with a hose like some think its ok to do) In
fact, the bulletin mentions "this condition is more apparent on vehicles in which customers
frequently wash the engine compartment".
Correction: replace rear bank knock sensor and build a "dam" around the sensor using RTV to divert
water away from the sensor. (swell........ make a "puddy dam".... that's high tech eh?_"
part no. for the sensor is 10456603
