Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety.
  • Allow the engine to cool before starting work.
2. Address External Oil Leaks
  1. Inspect Seals and Gaskets
    • Use a flashlight to inspect valve cover gaskets, oil pan gasket, and front/rear main seals for signs of oil leakage.
  2. Replace Faulty Gaskets
    • Remove any components blocking access to the leaking gaskets.
    • Clean the surface of the engine and the gasket surfaces.
    • Apply a new gasket or sealant as required and torque to the manufacturer’s specifications.
3. Check and Replace PCV System
  1. Inspect PCV Valve
    • Locate the PCV valve and remove it from the valve cover.
    • Check for clogs or damage; replace if necessary.
  2. Inspect PCV Hose
    • Check the hose for cracks or blockages; replace if damaged.
4. Perform Compression Test
  1. Remove Spark Plugs
    • Disconnect the ignition coils and remove the spark plugs using a socket and ratchet.
  2. Use Compression Tester
    • Insert the compression tester into the spark plug hole and crank the engine.
    • Record the compression readings for all cylinders.
    • If readings are low, further investigation into piston rings or valve seals may be needed.
5. Inspect and Replace Valve Guides/Seals (if necessary)
  1. Remove Cylinder Head
    • Disconnect the intake and exhaust manifolds, and any accessories blocking access to the cylinder head.
    • Remove the cylinder head bolts and lift the head off.
  2. Replace Valve Seals
    • Using a valve spring compressor, remove the valve springs and retainers.
    • Replace the valve seals and reassemble the components in reverse order.
