StevehS3 Posted June 2, 2023 Share Posted June 2, 2023 Looking at you previous photos I couldn't see a leak. I think the splatter around the UJ is normal as it is a greased joint and it flings the excess out. Link to comment Share on other sites More sharing options...

ScottR400D Posted June 2, 2023 Share Posted June 2, 2023 Looks like a slight rear seal leak to me. Mine does that and my UJs are sealed for life. Can't see how a UJ flinging grease off would get it there. Link to comment Share on other sites More sharing options...
John Vine Posted June 2, 2023 Share Posted June 2, 2023 #5: My view, too. I suppose it's just possible that the redundant speedo drive is weeping, but that seems less likely?Perhaps the OP could post up the photos again?JV Link to comment Share on other sites More sharing options...

John Vine Posted June 2, 2023 Share Posted June 2, 2023 #7 Interesting, thanks. I'm wondering if there's a leak ahead of the gearbox? Or maybe someone has spilled oil while topping up?I would suggest you wipe off all the oil, take the car for a spin, and then check again for leaks. A second video would be very handy.JV Link to comment Share on other sites More sharing options...
Rhys Mann Posted June 2, 2023 Author Share Posted June 2, 2023 Thanks John and no problem, will get a video done over the early next week as i won't have access to a ramp until then. Link to comment Share on other sites More sharing options...
Rhys Mann Posted June 4, 2023 Author Share Posted June 4, 2023 As a quick update, there doesn't seem to be any more fluid underneath the car after wiping off and driving out for a few miles, I have noticed that when she won't go into gear that the clutch has dropped down a bit, opened up the pedal box and couldn't see anything out of the ordinary there?! any ideas?

ECR Posted June 4, 2023 Share Posted June 4, 2023 Have you bled the clutch (I assume it's a hydraulic clutch) If not, do that first. It sounds very like a clutch problem rather than a gearbox problem. Link to comment Share on other sites More sharing options...
John Vine Posted June 4, 2023 Share Posted June 4, 2023 Good news about the lack of oil etc. For a thorough test, you'll need to do do a longer trip (20+ miles) to get everything properly warm.Re the clutch action, there's possibly some air in the system. Try bleeding the hydraulics. The other possibility is leaking seals in the master cylinder. Overhaul kits are available and easy to fit.JV Link to comment Share on other sites More sharing options...
Rhys Mann Posted June 4, 2023 Author Share Posted June 4, 2023 Willing to give it a go, any guides on how to do it? is it a straight forward job? Thanks again for all your support Link to comment Share on other sites More sharing options...
John Vine Posted June 4, 2023 Share Posted June 4, 2023 I'm not familiar with the Sigma. Does your bleed nipple etc look like this:If so, this is the procedure from the Assembly Guide:19 Remove the clutch master cylinder cap and protect the surrounding scuttle paintwork with clean cloths to prevent possible fluid leakage from causing damage to the paintwork.20 Locate the bleed nipple/key on the gearbox bell-housing (refer to Fig 1) and remove the bleed nipple cover. Ensure that the bleed key is in the position shown in Fig 1 (rotated fully clockwise) and fill the clutch master cylinder reservoir with fresh brake fluid that complies with SA3J 1703F DOT 4 specification. Replace the master cylinder cap.21 Rotate the bleed key counter-clockwise until it stops and place a length of flexible hose over the bleed screw and place the other end of the tube into a clean glass container and pour in sufficient brake fluid to cover the end of the tube.22 Pump the clutch pedal until good pressure is felt and clear fluid, free of air bubbles, flows from the bleed nipple. Rotate the bleed key fully clockwise, remove the pipe and replace the bleed nipple cover.23 Mop up any spilled fluid, check for clutch ‘feel’ and correct operation (repeat the bleeding procedure if necessary); finally, hold down the clutch pedal and check for leaks.That should apply generally.What year and model is your car? If you'd like a copy of the Assembly Guide. send me a Private Message with your email address.JV Link to comment Share on other sites More sharing options...
Rhys Mann Posted June 4, 2023 Author Share Posted June 4, 2023 Would this method work if i got one of the bleeding kits below and followed the video you think? https://www.amazon.co.uk/Mityvac-MV8000-Test-kit/dp/B00265M9SS/ref=asc_df_B00265M9SS/?tag=googshopuk-21&linkCode=df0&hvadid=310577373001&hvpos=&hvnetw=g&hvrand=9838398142550697009&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9180833&hvtargid=pla-316724733774&psc=1&th=1&psc=1 Link to comment Share on other sites More sharing options...
Rhys Mann Posted June 4, 2023 Author Share Posted June 4, 2023 Thanks so much John, will check this out and get back to you, a guide would be super useful, my email is rhysmann1@hotmail.com thanks Link to comment Share on other sites More sharing options...
John Vine Posted June 4, 2023 Share Posted June 4, 2023 #15: Don't bother with any of that. All you need is some DOT4 fluid, a clean jam jar and a length of flexible hose to fit over the bleed screw. Then follow the Assembly Guide procedureRe the Assembly Guide, versions can vary according to model and year. What model and year is your car? For now, I've sent you the 2015 text version. There are later ones, commonly called "IKEA-style", which (IMO) are not so useful.(ETA: You might want to edit your email address by adding a few spaces.

ScottR400D Posted June 4, 2023 Share Posted June 4, 2023 Re the oil leak, they're often very slow. I can take my car out after cleaning, for several decent runs and there'll be nothing. Then there'll be a tell tale dribble down the casting. I wipe it maybe twice a year that's all. I'd run the car for a few weeks and see if there's anything.

Area Representative Geoff Brown Posted June 4, 2023 Area Representative Share Posted June 4, 2023 Best of luck in bleeding the clutch system as access to & opening the bleed key can be a real swine of a job. Link to comment Share on other sites More sharing options...
John Vine Posted June 4, 2023 Share Posted June 4, 2023 #22 That's certainly the case on my Duratec, but is it also a PITA on a Sigma? My bleed nipple is hidden under a little alloy plate on top of the bell-housing. I thought the Sigma one was on the side of the b/h? JV Link to comment Share on other sites More sharing options...
StevehS3 Posted June 4, 2023 Share Posted June 4, 2023 I think it must be easier on the Sigma. It is a bit awkward on my 2017 but nothing more than that. It is located on the top of the b/h but not under a plate. Link to comment Share on other sites More sharing options...
John Vine Posted June 4, 2023 Share Posted June 4, 2023 #24 Is the Assembly Guide photo in #14 for a Sigma? If so, that's a top and not a side view then?I've just looked through the IKEA-style AGs (Sigma Edition 2.2 and Duratec Edition 2.3). Unless my eyesight is failing, there's no mention anywhere about bleeding the clutch. A very odd omission. JV Link to comment Share on other sites More sharing options...
