CAUTION: Remove the cylinder heads before removing the crankshaft. Failure to do so can result in engine damage.

CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTE: The flexplate, crankshaft rear seal, and the crankshaft rear oil slinger must be removed before mounting the engine on the engine stand.

1. Remove the bolts and the flexplate.

2. Using the special tools, remove the crankshaft rear oil slinger.

3. Using the special tools, remove the crankshaft rear seal.

4. Remove the bolts and the crankshaft rear seal retainer plate.

^ CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

Clean and inspect the sealing surfaces.
5. Mount the engine on a suitable work stand.

6. Remove the special tool.

7. Disconnect the RH camshaft position (CMP) sensor electrical connector.

8. Remove the stud bolt and the RH radio ignition interference capacitor.

9. Disconnect the RH variable camshaft timing (VCT) solenoid electrical connector.

10. Disconnect the 2 engine wiring harness retainers from the RH valve cover studs.

11. Disconnect the electrical connector retainer from the coolant tube.

12. Disconnect the 4 RH ignition coil electrical connectors.

13. Disconnect the cylinder head temperature (CHT) sensor electrical connector.

14. Disconnect the 2 engine wiring harness retainers from the LH valve cover studs.

15. Disconnect the LH VCT solenoid electrical connector.

16. Disconnect the oil pressure sensor electrical connector.

17. Disconnect the LH CMP sensor electrical connector.

18. Remove the stud bolt and the LH radio ignition interference capacitor.

19. Disconnect the 4 LH ignition coil electrical connectors.

20. NOTE: LH is shown, RH is similar.

Remove the 8 bolts and the 8 ignition coils.

21. Disconnect the crankshaft position (CKP) sensor electrical connector.
22. Remove the engine wiring harness from the engine assembly.

23. Remove the 2 bolts and the 2 knock sensors (KS).

24. Remove the stud bolt and the coolant tube.
^ Discard the O-ring seal.

25. Remove the bolt and the oil level indicator tube.
^ Discard the O-ring seal.

26. Remove the bolt and the RH CMP sensor.

27. Remove the bolt and the LH CMP sensor.

28. Remove the bolt and the CKP sensor.

29. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

CAUTION: When removing the valve cover, make sure to avoid damaging the variable camshaft timing (VCT) solenoid.

NOTE: The bolts are part of the valve cover and should not be removed.

NOTE: LH is shown, RH is similar.

Remove the bolts and the valve covers.
^ Fully loosen the bolts and remove the valve cover.
^ Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
^ Inspect the valve cover gasket. If the gasket is damaged, remove and discard the gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.
