DIAGNOSIS
Clean the leakage area with a shop towel. Start the engine, and look for new oil leakage from the area.
^ If you see any signs of leakage, go to REPAIR PROCEDURE.
^ If you see no signs of leakage, what looked like a leak may have been excess residue from a previous repair on another part. Continue with normal troubleshooting.
REPAIR PROCEDURE
1. Raise the vehicle on a lift about 10-12 inches, and make sure it's securely supported. You will be working under the hood, so make it a comfortable height from the ground.
2. Support the engine by placing a jack and a wooden block under the oil pan.
3. Remove the engine drive belt:
^ Refer to page 4-40 of the 2006-2009 Civic Service Manual or
^ Online, enter keywords DRIVE BELT, and select Drive Belt Removal/Installation (R18A1 and R18A4 Engine) from the list.
4. Remove the bolt securing the A/C line, then remove the upper torque rod.
5. Remove the battery ground cable bolt on the side engine mount bracket, and remove the side engine mount bracket.
6. Remove the timing chain case cover from the oil pump housing.
7. Remove the old gasket material, and thoroughly clean and dry the mating surfaces of the timing chain case cover and the oil pump housing.
8. Apply Hondabond HI evenly to the mating surface of the oil pump housing, following the time limits in the instructions on the container.
9. Install the timing chain case cover to the oil pump housing.
10. Reassemble in the reverse order of removal.
NOTE:
It is important that you wait 30 minutes before adding oil to the engine. Also, wait 3 hours before starting the engine to allow time for the Hondabond HI to cure.
