The Infamous Gm Engine Knock Well boys & girls , the so called "GM PISTON SLAP" has now turned into a constant full blown knock that won't go away even after full warm up and the damn thing sounds embarrassing as hell sitting at a signal light next to all the other cars with this matha ***** knocking away. Just rolled over 50,000 miles, what a bitch. ****** crawfishin General Motors wormed their way out of standing behind their defective engines by telling us, " Oh they all sound like that-not to worry-your good to go ~ problem? What problem, we don't here any noise , as long as it goes away after warm up ! I hope the Japs bury the sons a bitches including that phuckin boot licker Lutz .

Thinking about one of GM's remanufactured LS6 engines on sale for $2995.00 with a warranty. Anybody had any experience with this & is it a bolt in parts exchange swap ? My Z is a 2002 year model, are all the sensors & wireing connectors the same ~ anybody ?

Do you have aftermarket exhuast? Perhaps something is tapping the floorboard. There are alot of things it could be. That is why most dealerships don't want to get into it. They only want to diagnose you if there is a failure because tracking random noises down is usually a waste of time as EVERY Camaro on the road has been modified at some point in time.
Really, it sounds like you read that website and assumed you have a condition you may or may not have empathetically. If you want a super quiet engine I would get an econo box.
No offense please. Just observations. These motors are tough.
