Yay, back to the shop again!
As some of you may remember, I had to have my entire long block replaced under warranty after the dealer found a crack in my block. Prior to that, I had a check-engine nightmare that resulted in O2 sensors, 2 ECMs, a crankshaft, and the timing chains and tensioners all being replaced without resolution.
That was at 40,000mi. Until yesterday, I had reached 79,000 incident-free. The car threw a P0008 CEL last night, which is related to the timing chain being stretched, so she will be back in for warranty service sometime this week. The timing chain setup on our LY7s is the most over-complicated thing ever. Three chains, three tensioners, and four guides. Bleh.
Does anyone know of any aftermarket chains, or are we pretty well stuck with the OEM ones? Near as I can tell, this is a relatively common issue on all matter of LY7 cars.
