Haven't seen a thread. So I have decided to put together a simple one.
PLEASE NOTE: I am not liable for your DIY. Do this at your own risk. Just take care of yourself when you work on an automobile.
1. 10mm socket
2. 3/8" ratchet
3. 1/2" ratchet
4. 1/2" to 3/8" adapters, 3/8" extension, 1/2" extension as needed
5. AST oil cap removal tool. TOY 640. Get this from Amazon. See pic below.
5a. If you use 5, you need a 24mm socket.
6. Toyota oil filter 04152-YZZA1 or Lotus A132E6399S. Should come with 2 o-rings, a plastic funnel, and the filter. See pic below.
7. Toyota oil drain gasket 90430-12031 or Lotus A120E6461S
8. 5w40 oil about 6 liters or 6 quarts depending on brand of oil. 1 liter = 1.06 quart.
9. Oil funnel for filling oil. You need to have this.
Get the rear side of the car on a pair of ramps.
Get under the rear of the car and locate 19 pieces of this bolt. Be patient. Use a 10mm socket and remove them.
Remove the aluminium cover and set aside.
Locate the drain plug and oil filter housing. The housing is slightly hidden behind the sump towards front of the car, behind the passenger side.
Grab a tray and loosen the drain plug slowly. Let oil flow out onto the tray. Might take a while.
When this is done, replace the gasket and tighten the drain plug. Not sure about torque spec. Just hand tight. Do not over torque the plug.
The oil filter housing has a smaller oil cap that can be removed using a 3/8" ratchet. This cap is to ease the oil drain process from the housing by using the plastic funnel supplied in the oil filter kit.
I didn't use this. I went straight for the larger oil cap. The AST TOY 640 is a perfect fit. It can be loosen using a 24mm socket. As you loosen the oil cap, do it slowly, and let the oil mess drip down.
Once the large oil cap is removed, you can see where the larger o-ring is. Replace this with the new o-ring. Make sure you lubricate the new o-ring first.
There is even a notch for you to pry out the old o-ring easily.
Replace oil filter.
If you want, you can replace the smaller o-ring located inside the smaller oil cap. Make sure you lubricate the new o-ring first.
Replace the smaller oil cap. Torque spec is 13 Nm or hand tight is good.
Clean the oil filtering housing of any debris. Reinstall the large oil cap using AST TOY640. Torque to about 25+/-5 Nm.
Now, the bit about filling oil.
Ideally I want to fill oil when the car is leveled. But now that it's on the ramp, it's a two-person job to roll the car off the ramp without starting the engine.
Evora tech doc says the engine uses about 6.1 liters. Depending on which brand of oil you get, you might end up with a 5L or 5 quart jug. I have a 5L jug and 1 L bottle. I recommend putting in the jug of oil first.
The oil filler cap is located at really awkward angle. Hence you really need an oil funnel. Even so, filling oil when the car is on the ramp proves to be a balancing act. As you can see, the hatch shock can be in the way of pouring oil from the bottle. With the car on the ramps, I ended up adding oil from the passenger's rear quarter panel, while pouring oil into the funnel and making sure the funnel doesn't topple over. Make sure the end of the funnel is INSIDE the oil filler cavity ALL THE TIME. You don't want want to be filling oil and all the oil ended up dripping down to the engine.
Replace the oil filler cap. Start the car. Let idle. Check for leaks. Shut off car. Don't bother checking the oil level yet since car is still on the ramps.
Replace aluminum cover. Install all 19 bolts. Make sure each bolt is tight. Start engine and drive it off the ramp. Let the oil settle a bit before checking the level. For me, I added another 0.5L. In all, I only use 5.5L (5.81 quarts).
Drive the car around the block. Check the oil level again.
Park car. Drink beer and admire car.
