Walk back through the procedures you did to install the timing chain and match them up with the procedures I have listed below.
PLEASE NOTE THAT THIS IS FOR THE 2.2L 4Cylinder ENGINE. IF YOUR ENGINE SIZE IS DIFFERENT THAN THIS, LET ME KNOW.
Install or connect the following:
Upper balance shaft chain guide and tighten to 89 inch lbs. (10 Nm)
Small balance shaft chain guide and bolts and tighten to 89 inch lbs. (10 Nm)
Adjustable balance shaft drive chain guide and bolts and tighten to 89 inch lbs. (10 Nm)
Turn the tensioner plunger 90 degrees in its bore and compress the plunger until a paper clip can be inserted through the hole in the plunger body and into hole in the tensioner plunger.
Timing chain tensioner and bolts and tighten to 89 inch lbs. (10 Nm)
Remove the paper clip from the balance shaft drive chain tensioner.
Install the crankshaft sprocket with timing mark at the 5 o'clock position
Lower the timing chain through the opening in the top of the cylinder head. Carefully ensure that the chain goes around both sides of the cylinder block bosses.
Install or connect the following:
Intake camshaft sprocket with the INT diamond at the 2 o'clock position
Hand tighten a NEW intake camshaft sprocket bolt.
Route the timing chain around the crankshaft sprocket with the second silver link aligning with the timing mark.
Route the timing chain around the intake camshaft sprocket with the copper colored link aligning with the INT diamond.
Timing chain tensioner guide through the opening in the top of the cylinder head and tighten the bolts to 89 inch lbs. (10 Nm).
Exhaust camshaft sprocket with the timing chain silver link at EXH triangle aligned at the 10 o'clock position.
Use a 24 mm wrench to rotate the camshaft slightly, until exhaust sprocket aligns with the camshaft.
Hand tighten the NEW exhaust camshaft sprocket bolt.
Install the fixed timing chain guide and tighten the bolts to 89 inch lbs. (10 Nm).
Apply sealant, GM P/N 12345382 compound to thread and install the timing chain guide bolt access hole plug. Tighten the access hole plug to 30 ft. Lbs. (40 Nm).
Timing chain upper guide and bolts and tighten to 89 inch lbs. (10 Nm)
Measure the timing chain tensioner. In a fully compressed, non-active state, the tensioner will measure 2.83 in (72mm). A tensioner in the active state will measure 3.35 in (85mm). To put the tensioner in a non-active state, hold the flat end of the tensioner with a wrench and rotate the piston clockwise for slightly less than one full turn.
Timing chain tensioner and tighten the tensioner to 55 ft. Lbs. (75 Nm)
Use a suitable tool with a rubber tip on the end. Feed the tool down through the camshaft drive chant to rest on the timing chain. Then give a sharp jolt diagonally downwards to release the tensioner.
Use a 24 mm wrench to hold the camshaft and tighten the new bolts to 63 ft. Lbs. (85 Nm) plus an additional 30 degrees.
Install the valve cover.
Install the engine front cover as follows:
Install front cover gasket, cover and cover-to-engine bolts.
Install the water pump-to-front cover bolts. Tighten all the cover bolts to 15 ft. Lbs. (20 Nm).
Install the drive belt tensioner and tighten the bolt to 33 ft. Lbs. (45 Nm).
Install the crankshaft balancer and bolt.
Use crankshaft holding tool J 38122-A to prevent the crankshaft from rotating while tightening the crankshaft balancer bolt. Tighten the bolt to 74 ft. Lbs. (100 Nm) plus an additional 75 degrees.
Install the engine splash shield.
Install the drive belt.
Install the front wheel.
Connect negative battery cable.
Let me know if this helps the noise. If it doesn't, or if you did these steps already, the noise could be coming from another component.
