Fairly easy job.
Step 1: Disconnect Battery
Step 2: Get front end of car up on jack stands or up on a lift if you have access to one.
Step 3: Drain oil. Pull the dip stick up a little too.
Step 4: Remove starter
Step 5: Remove flywheel shield
Step 6: Disconnect the steering idler arm and lower it out of the way.
This will get the steering component out of the way to allow you to get the oil pan out.
Step 7: Remove oil pan bolts and you may have to gently tap on the pan to break it free. Use a soft mallet.
Step 8: Scrape all old gasket material off of both surfaces. Remove end seals.
Step 9: Reinstall pan gasket and bolt the pan to the engine. Use a couple dabs of RTV where the pan gasket meets the end seals.
Step 10: Torque oil pan bolts. The 1/4" bolts are about 90 in. lbs. and the 4 5/16" bolts are 162 in.lbs.
Then just do everything else in reverse order. Fill with oil, connect battery and fire it up making sure the oil pressure jumps up quick.
If your engine has a lot of miles on it. It might not be a bad idea to toss a new oil pump and drive in there while its opened up.
I think I hit most of the steps here. Others will chime in with other tips and tricks.
