Working on a ‘12 Malibu with the LE9, Ecotec 2.4 engine and I just replaced the timing set; I noticed that as I turn the engine over by hand, the exhaust vvt sprocket has about a 1/4 turn of play before it actually moves the camshaft. Turning the cam itself using the flats yields the same results…1/4 turn of movement of the cam before the sprocket teeth actually engage and move the chain.
Are these things supposed to be locked while not running? The intake vvt sprocket teeth move directly with the camshaft so I’m curious if that’s how they’re supposed to operate.
