So far I have :

-A borescope inspection of the engine to check the rocker arms and timing chain tensioner

-Check for any oil consumption issues that could indicate piston ring problems

-Inspect the water pump for any signs of early failure

-Check the engine mounts for wear

-Check the serpentine belt condition

-Check the vacuum lines for any cracks or leaks

-General drivetrain inspection
