Oil Change for 2014 360 wet sump

[dstb]

I am a recent buyer of a 2014 360 and looking for advice on an oil change.  The sales sheet I received stated this was a dry sump system but there is no external tank.  Only a catch can.  I believe it is actually wet sump.  Please see the attached photos.  I am looking for the correct oil drain plug.  I think this is the bolt shown in the right side photo.  But the left side photo shows another type of bolt.  I'll take any advice.  Thanks.

I'm not familiar with the Caterham Duratec sump setup but the black plug should be the drain, and the blue anodized plug I think would be where the finger filter is located. I assumed the finger filter was only on dry sump cars, but I guess I was wrong.

I have this sump on the Westfield.  I have always used the blue plug as that is what Raceline told me to use when I bought it years ago, but I've seen comments that Caterham recommends the smaller plug on the other side.  I've never bothered to measure which port is lower, but it might be worth checking on your car.

 

Is this the car that was on Bring a Trailer a couple of times this Fall?  If so, I called him out on his dry sump claim in the initial listing, which he ignored.

Thanks to you guys for chiming in.  I'd say both plugs are at about an equal height.  I guess I might just have to open both and see what is what.  I feel like the blue plug may be there to facilitate a dry sump setup IF it was installed.

 

This is the BAT car.  The sales sheet from Hillbank detailing all the options shows dry sump at a $3,500 tab.  I'm sure that's where that came from on the BAT listing.  It also has the catch tank but no separate oil tank/cooler as far as I can see.  Pretty confusing to me but I'm new to all this.

One thing I discovered after removing the sump to reseal a leak is that a fair amount of oil is left over when draining via the ports.  I switched to an oil extraction pump which does a better job of removing all the oil.

 

You definitely have a wet sump.  The dry sump pan is quite different, and as you note, it would need a separate tank.  The initial listing for your car also mentioned it had a catalytic converter, but the pictures show it is fitted with the cat-bypass pipe.  I suspect the previous owner didn't really know very much about these cars. 

 

There are a lot of very knowledgeable people on the forum; don't hesitate to ask questions as you begin to learn your car.  In return, you do need to post photos of the car with the under-body LEDs illuminated.  I have never heard of those before on any type of se7en

You are correct on all counts.  Thankfully I have no emission test here and I believe the seller to be a good guy and casual owner.  But it is hilarious you mentioned the underbody lights.  I removed them with extreme prejudice and they will never shine again.  I’m an old school kind of guy.  This car is for driving.
