Just a thought, I have changed timing chain before and when I put tensioner on it would throw off timing mark. I would offset the timing mark one tooth and when I would put the tensioner on the timing marks would line up.
Hope some of this helps, good luck

I'm not sure if the engine has a cam chain or belt but if chain it might be the tensioner.

Hi there, the following information are for a 2004 Grand Am 2.2L, I hope it helps:

    3.8L Engine
    

    1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
    2. Record the radio anti theft code data.
    3. Remove the engine from the vehicle.
    4. Remove the drive belt. Remove the power steering pump. Remove the air conditioning compressor.
    5. Remove the alternator. Remove the drive belt idler. Remove the drive belt tensioner. Remove the water pump pulley. Remove the intake manifold.
    6. Remove the connector bracket from the left cylinder head cover. Disconnect the right ignition coil connector, condenser connector and remove the bracket.
    7. Remove the left cylinder head cover retaining bolts. Remove the cylinder head cover from the engine.
    8. Remove the right cylinder head cover retaining bolts. Remove the cylinder head cover from the engine.
    9. Set the No. 1 cylinder to TDC on the compression stroke. Turn the crankshaft pulley and align its groove with the timing mark T of the lower timing chain cover.
    10. Check that the mark of the camshaft timing sprockets are in straight line positioning on the cylinder head surface. If not rotate the crankshaft 360 degrees. Do not rotate the engine counterclockwise.
    11. Remove the oil pan. Remove the crankshaft damper pulley. Remove the timing chain cover.
        NOTE Be careful not to damage the contact surfaces of the cylinder block, cylinder head and timing chain cover. Before removing the timing chain, mark the right and left timing chains with an identification mark based on the location of the sprocket because the identification mark on the chain for TDC can be erased.
        
    12. After compressing the timing chain tensioner, install a set pin. Remove the right cam to cam guide. Remove the right timing chain auto tensioner and timing chain tensioner arm.
    13. Remove the oil pump chain cover. Remove the oil pump chain tensioner assembly. Remove the oil pump chain guide. Remove the right timing chain.
    14. Remove the right timing chain guide. Remove the oil pump chain sprocket and oil pump chain. Remove the crankshaft sprocket, oil pump and camshaft drive gear.
    15. Remove the left cam to cam guide. Remove the left timing chain auto tensioner and timing chain tensioner arm. Remove the left timing chain.
    16. Remove the left timing chain guide. Remove the crankshaft sprocket and left camshaft drive. Remove the tensioner adapter assembly.

    To install:
    
    1. Check the camshaft and crankshaft sprockets for wear and damage, replace as required.
    2. Inspect the tensioner arm and chain guide for wear and damage, replace as required.
    3. Check that the tensioner pin moves smoothly when the ratchet pawl is released with a thin rod.
    4. The key of the crankshaft should be aligned with the timing mark of the timing chain cover. This indicates that the piston is at TDC on the compression stroke.
    5. Install the tensioner adapter assembly. Install the crankshaft sprocket and left camshaft drive.
    6. Install the left timing chain guide and torque the retaining bolts 14-18 ft. lbs.
    7. Install the left timing chain. Be sure to install the chain with no slack between the camshaft and the crankshaft (crankshaft sprocket, timing chain guide, exhaust camshaft sprocket, intake camshaft sprocket). The timing mark of each sprocket should be matched with the timing mark (color ink) of the timing chain at installation of the timing chain.

I broke my Brake Vacuum Pump and oil was EVERYWHERE!! Cheap part to buy and easy to fix yourself.
I also drive a 1994 Pajero 2800 intercooled 4m40

Have you checked the oiler supply to the timing chain and the chain tensioner Just a thought. The guides usually only break from the lack of tension on the chains.

Ohhhhhh, sometimes folks get in a hurry changing belts and disconnect the crank sensor. Its sow by the crankshaft pully. It's a plug that came apart.
