Subsequently, remove the Oil Pan to engine front cover bolts and the engine front cover attaching bolts, and remove the engine front cover. Check the movement of the Timing Chain that should not be more than 25 mm (1 inch) and the timing sprockets for wear. Clean the gasket mating surfaces at the cylinder block; and if the Oil Pan Gasket is too swollen, remove the Oil Pan in order to replace the gasket. Replace the engine front cover if necessary upon inspection. Put on the engine front cover gasket and put in the engine front cover, being sure to apply sealant gm p/n 12346004 (Canada P/N 10953480) or equiv. To the bolt threads. Tighten the engine front cover bolts to 20 nm (15 ft. Lbs.) and then use the torque angle meter (J 45059) to turn an additional 40 degrees.

Install the otherwise drive belt tensioner assembly, refraining from changing crankshaft sensor, then install crankshaft sensor, crankshaft sensor shield, crankshaft balancer with its bolt, as well as the right Engine Mount Bracket.
