I had a similar leak in my new car after the 1K checkup. It was an extremely slow leak which I monitored. It went away after I changed the oil myself at 5K.

In my old car I spilled some oil while refilling the oil, and it later scared the hell out of me when it formed a stain right below the tranny. It took me a minute to remember my spillage and I had to laugh.

Whenever you pull a wheel, take a flashlight and look across the top of the service panel. Any leakage is easily visable and should be dealt with promptly.

FWIW, there was an oil film all over the filter when I caught it the first time. I doubt it was from spilt oil... they would have had to spill at least 1/2 quart and spill it during both oil changes. This was a good bit of oil... there was oil dripping from the access panel screws and a fair amount windblown to the rear diffuser.

I haven't pulled a rear wheel. I'll try your flashlight advice on a warmer day. Thx.

I notice a little bit of oil on the top of my service tray too. FVMC changed my oil on the first service at 800 miles. The car was at about 1600 miles and I changed the oil myself tihis time around, just before this winter. That's when I noticed the oil leak, there was a small oil stain on the top of my engine service panel. Upon inspection there was a drop of oil waiting to fall right at the bottom of the oil filter, how convenient, I gather from this that it looks to be a very slow leak at the oil filter. I did not see any leaks when I replaced the filter and ran the car for a bit.

I drove the car yesterday and will keep an eye for a leak there at the oil filter area and see if it happens again.

I seem to be following the same experience. We'll see if it disappears at the next engine oil change.

I used this 2 LED headlamp and held it in my hand behind the rim and shining it on top of the service panel.


You can look through the LSS rim spokes (no need to take the tire off or jack the car up) and clearly see the top of the panel for any oil spilled. I cleaned the panel very well so it should be easy to tell if there's any new oil leaking now. I did not see any but I have just driven the vehicle for about 10 miles. I did hit the 2nd cam so the oil pressure should have gone up enough that if there's a leak I would have been able to see it, even a drop would have shown up and I'm pretty sure I could have spotted it. We'll see I will pediocally check for it now.

Wow, a Lotus leaking oil? Only the British can take a perfectly sealed Japanese engine and make it leak, so I knew it was only a matter of time before an oil leaking thread showed up. Maybe the under tray panel is really there to catch oil drips and not to clean up the air flow? If so, it was nice of them to cut in the NACA ducts so the trapped oil could eventually leak out onto the garage floor!
I wouldn't get too concerned over a small drip as long as it doesn't turn into a major leak. I have yet to see a Lotus that doesn't leak some sort of vital fluid eventually.

You will find the same oil grime there after a short time of driving -- guaranteed. It appears that we'll all need a new O-ring or possibly a replacement sandwich adapter.

It is what your oil filter is mounted to. If you look at the filter and where it's mounted, you'll see 2 oil lines and they connect to the sandwich plate. It is use to route oil to the oil coolers. Usually there is a valve in the sandwich plate that will open and close depending on temperature and allows hot oil to flow to the oil cooler(s).

Well, surferjer says he had a leak but upon changing the oil filter it did not exhibit the problem anymore. So far I see no signs of a leak anymore but then again I've only driven it a few times, well see in the future oil changes. I'll be keeping an eye on it.

Same here. 8000 miles since I wiped the grime off and no leaks.

Here's a few pics of it:

Update - leak from oil pan

I just got my car back from the dealer after the long list of warranty work.

They found that there was a leak in the sealant between the oil pan and the engine. The oilpan was removed, cleaned and resealed. Road testing found no more leaks. I will be pulling the diffuser in a couple of weeks time to double check but it sounds like the issue has been fixed.

I just did what I posted in this thread (post #27) and saw no oil grime on the top of my service panel. There was no need to take the service panel off to verify this.

lemme know if it works for you, hope it does. I used my 2 LED light that is very small and easy to get behind the rim and light up the top of the service panel. I am easily able to view it through the LSS rim's spokes.

12000 miles no leaks since wiping the grime off at my first DIY oil change.

It's 2018 and I have the same issue of a single drop off oil on the bottom of my oil filter. I looked underneath and saw that the sandwich plate bleed nipple had a drop coming out.

Is this common? Do I just tighten the bleed nipple?Name:  IMG_20180505_101406.jpg
