How easy is it to replace the oil pan gasket?
Do you need to raise the engine, take off a bunch of parts, or simply unbolt and re-bolt?
Do you need to use sealant?
How tight are bolts retightened?
Do you
have the same problem?

You do not have to remove any mounts or anything. Make sure to remove the oil level sensor from the side of the pan before removing so you don't break it. Use a 1/4 inch bead of silicone sealant on bothsides of the gasket.(Make sure surfaces are free of dirt and oil or the silicone wont stick) Finger tighten all the bolts and then tighten the oil pan retaining bolts to 14 N m (124 lb in). It is a good idea to let it sit for about 30 minutes before adding oil just to give the sealant alittle time to cure.

I have unclipped the wire connection going to the oil level sensor.
How do I remove the oil level sensor?
(I have all the bolts off the pan, except left one loose to hold it up, but the pan will not drop off. I assume that this is due to the oil level sensor).

Also, when applying the sealant, do you apply it where the red rubber gasket is on the gasket (follow it around)?

OK.
The oil sensor just unscrewed.
Now, to remove the old gasket, do I need to remove the starter, or the oil pickup?

You do have to remove the oil pick-up tube. And when you aply the sealant what I do is put a small bead all the way around the pan and spead it with my finger then do the same on the gasket. Make sure and get a new oil pick-up tube gasket aswell.

Thanks for the reply.
By the time I read it, I was already finished.
I did not recall seeing a gasket on the oil pickup tube, but maybe I just did not see it. How important is it to have been replaced?

Everything went back together smoothly and appears to have no leaks. I think this took a while being that I had not done it before and did not want to break anything. Hopefully there will not be a next time, but if there is it should be easier!
