I am sure not knowing the original design situation or how it came to be that this is a special case since it appears very limited production exists. It also appears that none were installed on original engines. In other words this was a GM after market improvement which really never took off.

Why do we need spare Aluminum Chain Tensioner Housing Upgrades

Because GM won?t admit the rattle at startup was a defect. You are correct this never showed up as a correction on the entire production model run. I think "think mind you" this was created by an engineer as a solution to the problem that bothered a lot of original owners. Can you imagine some owners out there that were under warranty when there 70K in some case 100K ZR-1 started to rattle like the cams were going to fly out of the engine? It was done either to appease the earlier original owners or somebody at GM was so damn bothered by the problem that they determined to provide a solution. To GM and most ZR-1 owners this was an LT5ism.

Just like the letter GM wrote in response to the early Multech fuel injectors. GMs stance was basically these performed as designed and the problems associated with them due to the changes in fuel formulation (Methanol MTBE) is not our problem. The fact that these are melting due to this change in pump gas is your problem.
