Oil Pan, Remove & Replace

1. Remove undertray
2. Unbolt midpipe from exhaust (allows more wiggle room to remove the header)
3. Unplug oxygen sensor harness. Use a flathead screwdriver to release the clip holding the wiring to the engine. This allows you to drop the header down without removing the oxygen sensor
4. Remove header
5. Remove oil pan bolts and carefully pry lower pan pan off, taking care not to damage the alumium mating surface of the upper oil pan
6. Inspect and remove any RTV in the pickup with a pick tool
7. Clean and prepare mating surface of the upper and lower oil pan. Because aluminum is a soft metal, it is preferrable to use plastic tools or a dulled putty knife, rather than a razer blade
8. Apply RTV to the mating surface of the upper pan (following the service manual) or the lower pan (commonly done)
9. Reinstall the oil pan and fasten the bolts hand tight without tools.
10. Torque the bolts according the following specs and order
11. Reinstall header and exhaust midpipe
12. Plug in oxygen sensor to the header
