Sump leaking - Land Cruiser Toyota Cars & Trucks

-Drain the engine oil through the drain bolt located under the oil pan (sump).
-Preserve the used oil in a sealed canister to be disposed off later.
-Remove the oil pan bolts from all around and keep them in a tray.
-Oil pan is attached with a silicone sealant so it need a little practice to be separated from the cylinder block assembly. To remove it, tap it with a rubber, wooden or plastic hammer. If it is too hard to remove insert a thin wide chisel slowly from different places turn by turn but not damaging any of the surfaces.
-Finally insert a slightly thicker and strong wide chisel from the front side and force it slowly downward.
- Take out the oil pan carefully.
- Clean and wash it thoroughly with detergent and let it dry.
- Clean the lower surface of the cylinder block.
- Apply 3 to 4 mm thick layer of silicone sealant RTV-Grey to the oil pan mating surface.
- Hold the oil pan near the cylinder face not touching the cylinder face and center the pan by just tightening a few turns of oil pan bolt. Put another bolt on the opposite side. Screw in another bolt to the side of the pan and one more bolt to opposite the third bolt. Then screw in all the remaining bolts slightly.
- Seat in all the bolts and tight the bolts in many attempts.
- Make sure the silicone sealant flows out equally from all around the all pan.
- Wait about 1 hour to let the sealant dry.
- Install new oil filter.
- Pour new recommended engine oil and bring it to the upper level.
- Start the engine for ten seconds, switch it off and check the oil level again.
- The job is complete now.
