DIY - Oil Change Reference for 2GR-FE

I have the ratchet and its great but very easy to over torque to 30ft lbs til it stops. If you have it set to tighten by mistake on a small fastener you'll regret it. (Done that more than once) I'd highly recommend their M12 cordless screwdriver/driver (or similar brand if have batteries for that brand). It has variable max torque settings so you dont accidently strip screws and small bolts out. For the undertrays I used about a '3-6' setting on the tool then go back and finish tightening them by hand.

Good idea however it depends how much room you have to work under the Emira. The screwdriver/driver you reference takes up more space, compared to the ratchet. If you're working under a 4-post lift, then for sure it's better to control the torque with the screwdriver/driver. If space is at a premium, the ratchet would likely work better and then you'll have to take extra care with torque.

Either way, your comments about overtorquing are a good warning and appreciated.

Note: one other difference, not that it'll matter much to most, is the ratchet weighs in at 16 oz (a pound) whereas the screwdriver/driver weighs 1.95 pounds (almost double).

BTW and I may have mentioned this before (?), I love your avatar, which reminds me of how I'm feeling while driving my Emira sometimes (lol).
 
A couple of observations on DYI oil change.

As you guys know, the 7mm hex bolts pictured below have to be removed. These bolts attach to zinc coated bolt clips and these are not the same bolt clips used on earlier Lotus...They are kinda flimsy.

These clips are the attachment point for all the 7mm bolts with the black washers. Anyone doing their own oil change needs to be extra careful when reinstalling the diffuser tray to line up the bolt clip so as to not bend or deform the bolt clip. I bent one and had to remove the entire under-tray in order to straighten it out and reattach. PITA b/c of crappy hardware.

After getting it down for the second time, I put a light coating of WD40 on all the bolt clips and that seemed to do the trick. All the 7mm bolts went into place without any drama. Torqued to spec and all good.

I'm ordering a few extra bolt clips from my dealer b/c its clear to me the hardware isn't up to the repeated abuse that it'll see over the life of the car and eventually spares will be needed.

Do you know the part number for those clips?

Nope...Just asked my dealer to order me a few spares. they didn't have any in stock and said Lotus has them on back order. so it might be some time b/f they come it.

It should be a standard M5 bolt clip / U-nut. there are stainless ones you can get on amazon if needed while we wait

I've made various hardware purchases with McMaster-Carr (including clips similar to what you are looking for) with good results. They many times will show a CAD drawing of their items. Maybe they have an alternative readily available for your needs.

 
What’s the point of the magnetic drain plug? So you don’t accidentally drop the plug in with the old oil?

any ferrous material that ends up in the oil will either make it up in to the filter or settle at the bottom of the pan. the magnet on the drain plug helps to "collect" most of that ferrous debris at the tip of the plug. when you change your oil, you can actually see if you have observable ferrous debris, and then it's easy to clean off or, if significant, you can collect it and have it analyzed to see what's going on in the engine. without the magnet, it will just end up elsewhere.

keep in mind that if something is large enough for you to see with your eyes, it may not show up at all during a used oil analysis, which only tests the chemistry and microscopic content of the oil.
 
What's the torque spec for the filter housing?
 
I was thinking of just cutting a hole and then cutting a piece of aluminum that’s bigger by about an inch — drill holes and place clips just like the stock one attaches to up near the rear of the massive shield.
Hi KitKat.
I was seriously planning on creating a 4 bolt trap panel to facilitate future oil changes, following your idea. However, after watching an Emira oil change video on YouTube, I came to realize that the oil pan and filter are located on the right side (observing from rear-to-front of the car) and seem to be directly in the vertical line of the under tray's extruded aluminum slats that follow through to the rear plastic diffuser.
There's a large middle section of the under tray which would be an ideal spot to adapt such a trap panel, but I believe that there's no spot in that mid-section that would allow for a proper angle to access the oil pan and remove/replace the filter. My assumption is just based on what i observed in the YouTube video and by checking the external side of the under tray. I'll verify if this is indeed the case, when I remove the under tray for the next oil change, unless someone else here can confirm or contradict my suspicion beforehand, and I definitely wouldn't mind being wrong in this case.

I’m almost due for an oil change as well, I’ll check when I do it, maybe this weekend.
