3. Inspect and Adjust Valve Clearance

Sub-steps:
1. Remove the valve cover by loosening the bolts with a socket set.
2. Check the valve clearance using a feeler gauge, comparing measurements to manufacturer specifications.
3. Adjust the clearance by replacing shims if needed, or tightening/loosening the rocker arms.
4. Reinstall the valve cover with a new gasket, torquing the bolts to the proper specifications.

4. Inspect Timing Chain/Belt

Sub-steps:
1. Remove the timing cover by loosening the necessary bolts.
2. Examine the timing chain/belt for wear, slack, or damage.
3. Replace the timing chain/belt if it shows signs of wear or if the tensioner is faulty.
4. Reinstall the timing cover with a new gasket, ensuring proper sealing.
