Yes, end cap came off when i caught it on the extra large curb bits on the final chicane, which meant it all flew out on the start/ finish straight!

This thread is timely for me as I caught the end of my exhaust on a curb at donington yesterday and all the packing came out (sorry for the red flag if you were there). Which filing do you choose?

Have you considered adding a rule that drivers from Watford whose first name starts with A get a 2 second benefit because they are slower than the others? Asking for a friend

I was told that this is a typical issue with the standard fluid cap - another club member told me that after the first time on track in his Academy year Caterham did a brisk trade selling 'race caps' for the fluid reservoir as so many leaked. You lose the brake fluid sensor as the cap doesn't have the links, but on the plus side the paint work is saved

There's always the risk of user error when I'm involved!! Pretty sure that its not the dipstick as I cable tie that down having been warned it can let oil out going round fast corners

A quick update - checked this morning and no oil has dropped at all since I put it away after the Blyton sprints at the weekend. I put some blue paper roll underneath so I could see even a single spot, and nothing. Maybe will leave taking the sump off for now as if it 'ain't broke, don't fix it. However, if it does start going again I'll be straight back to this thread for the helpful advice it has.

Thanks Scott, very helpful link The special tool isn't cheap, its £45, with another £10 for the adapter!

Sorry, I confused myself. I was planning to take the sump out in situ, so of course I won't be changing the RMS!

Ah, that would explain why I can't find the gasket on the parts website! @ScottR400D Worth replacing the Crank Seal while I'm at it? They're only £18 and if there is a risk around damaging it I may as well get a new one after the sump is off.

Thanks for the suggestions and help everyone. Oddly, the leak stopped this weekend - was at Blyton both days for the sprints and I put paper towels on the floor under the sump after each run and when it cooled down overnight and there was not a drip to be found. The leak is clearly very very slow. I probably need to change the oil anyway as its had the same stuff in it for a few events now, so I'll drain and remove the sump and take a look at it (welder flaw spray is next in my google list!). One question, when I remove the sump, is it worth replacing the gasket around it just in case? Can't see one for a Sigma (wet sump) on caterhamparts, might drop Chris @ Redline a note if it is worth it.

Thanks Graham!

Thanks Graham - have joined the group, hopefully they will resend on the group shortly (as you can't see messages in a Whatsapp group before the point you joined).

Running order is in the Blyton final instructions (on this page https://www.nottinghamsportscarclub.co.uk/event.php?id=60), but I can't see the paddock plan anywhere. The instructions do say that it will be marked out and to look for your area and number.

Early get away on Sunday though. Its a long drive back to Watford from Blyton!

It's a wet sump. Cant see any oil further up anywhere, but have wiped it all down and will try and track the path of the oil later tonight, if any has come out

Hi all Thought I would post a few pics to get some thoughts on where to start looking for the source of a very small leak. Just looking over my car ready for Blyton sprint next week I found a small patch of what I think is engine oil on the floor underneath it. The car hasn't moved for around 4 weeks (thanks to a stupid foot injury causing me to drop out of the Curborough sprint) and has been sat under a cotton cover in the garage. It looked at first like a leak in the seal between the engine block and bell housing, but when I ran my finger along the sump I found a very thin layer of oil down one side, leading to what looks like a knick taken out of the sump by a stone. Closer.... The question is, does that look like it could be the culprit for what is quite a small leak, and if so do you think its repairable or is it new sump time (@£500 or so!). OR, am I looking in the wrong place for the leak? Car is a 2016 ex Academy, Sigma engine.

I have a PRG mini sport with an almost identical bed size, and my S3 is fine on it. Just need to be careful driving on it so that the exhaust isn't caught on the side. https://www.prgtrailers.co.uk/trailer/minisport/

I have a 2016 Sigma engine with a 5 speed gearbox and BMW diff, so very similar set up to you and I wear earplugs due to the whine around 50mph. Have always assumed its gearbox whine.

Previous owner had tried to use some bolts on one of my wings but they rusted and the wing fell off (after going over a curb at Stowe corner, luckily just before the pit entry), so used some Tiger Seal which seems to have held up very well for the last year or so. Still securely stuck down - its nasty stuff though, so wear gloves to apply it. However, the big head approach in the linked to threat looks great. Will be doing that next time.

Not me unfortunately, fell off a ladder earlier today getting my stuff ready for tomorrow and now I can't get my race boot on, let alone drive. There's always next year!

@DerekH Funny, I was thinking exactly the same thing after yesterday - I ended up putting in my Sony in ear headphones that have active noise cancelling as my ear plugs weren't up to the job for such a long period! Off to read Stephen's reply and Jonathan's links....

Thanks Ian (and Alan who sent me a direct message). Will stick with RaceChrono for now and see how I get on at Curborough with it

@garth What pressure were you running? Reading this makes me think I need to check mine!

As I slowly get sucked into the quest for more speed to try and lift myself off the bottom of the timing charts, I've picked up a Vbox sport to log my runs and give me something to analyse afterwards. What software do people use to analyse the data ? The free one for Windows from Racelogic actually looks quite good given I don't have a video feed to sync yet, but would mean I have to bring a laptop to each event. I've also tried the RaceChrono phone app which seems okay, given the relatively simple data that the vbox sport records, and it means I don't need to bring a laptop along. I have an android phone rather than iPhone, which means the free Racelogic native apps are out. Permission from The Boss to spend more heavily on a video linked vbox system or a GoPro was denied, so I have a very cheap video camera that works well enough to watch back which clipping points I missed on a run, but linking them together will have to wait until I've hidden enough cash away without The Boss noticing. I suspect a full sensor set up like Richard's isn't going to happen soon!

My cover is just held on by those fasteners. They work well, but no idea where to get replacements from
