I recently busted my lower oil pan and now its leaking everywhere. So I've decided I'm going to replace it myself. I talked to a local Lexus dealership and I got all the part numbers I'll be needing but they weren't able to give me torque specs or any advice.
Before I start grabbing parts, has anyone had to replace their lower oil pan on their IS? IS350 to be exact?

You're just asking about the lower oil pan (black) and not the upper one (unpainted), right? I've never done one on the floor, but it's just 15 bolts and two nuts. Loosen them off and get an oil pan cutter (or something to wedge in between the pan) and hammer it in. Be careful not to mar the mating surface on the upper oil pan. Clean it as best as possible with a wire brush or a scraper and follow up with brake clean to get any residue off. Use a good silicone. I use Toyota Seal packing 103(FIPG) p/n 00295-00103. Don't apply too much! The torque for the 10mm bolts and nuts are 7 ft.lbs..

Yes just the lower oil pan. Thanks for the advice!
I'm glad it'll be easy to replace. The dealership was going to charge me $600 + tax for the repairs.
I'll be picking up that exact silicone when I stop in to pick up my parts.
Thanks again and I'm sure your tips will help others in the future.
