Hi All

As above my R26R has a leak from RMS. Picked up at service by K Tec racing in November, but was only a weep (I did ask but they are not authorised to carry out warranty work) . Has now got quite bad, and as the car is out of warranty tomorrow, I registered the fault with Reanault UK over the weekend. They are calling me tomorrow to get details. My main question is can anyone rocommend a good dealer to do such warranty work around Hampshire or Dorset. Nearest Reanault Sport Dealer to me is Martins of Basingstoke. Anyone had any experience??? I expect I will need a new clutch as the linings will be soaked in oil. Basically like all owners (I would imagine), I am wary of letting 'anyone' :cowboy: 'have a go' at the car, as it is such a rare beast, so your advice would be appreciated. :)

Cheers

OB

Thanks for reply, and to be honest Bristol is not too far for me. Good to know you have 'happy' R26 customers. Basically, regardless of marque or model, I think you'd agree any 'main dealer' or any 'franchise' for that matter can be a lottery, so it's good to get a few recommends of good service.

K Tec said they had seen quite a few R26R's with this problem, and to be fair they see probably more R26R's than most I'd guess. Apparently these models were prone as the engines were crated up and sent to the Dieppe motor sport division ???? for the cars to be built, and the engines sat around quite a long time. The weight of the unsupported crank, (no gear box fitted at that point), bears down on the RMS and deforms it slightly, hence the ongoing leak. I am an engineer by trade, so can understand the theory of this, and have had experience first hand on high pressure hydraulic systems. However, if this is the true cause or assumption I do not know?

Anyway thanks again for reply, and feedback.

Cheers

Rob

I know of one car. It was replaced and a subsequent leak was found on the sump gasket. Both were extremely small and caused no cause for concern. Warranty picked up the tab. To the engineers: Should it ne expected to see this again?

If its under warrenty go for it but a lot of them weap/leak from the crank main seal from what i've seen (4+ with the same leak). I've replaced the crank seal and the sump gasket + rhodoseal on mine and it still leaks, so must be a gap somewhere on the bearing cap sealant. Hasn't caused a problem in 4 years now, the oil stays well behind the flywheel.

You can see the extend of the leak in these pictures.

The sides of the no.1 main bearing cap have to be filled with rhodoseal to seal them, if there is a gap anywhere the oil finds it and leaks through to behind the flywheel. Its more an annoyance than a real problem and you've only solve it by pretty much a full engine rebuild where you'd reseal all the caps from scratch. Otherwise its not worth worrying about.

The same can be said for the timing end plate too, some leak from here too for the same reason. Think its just luck of the draw who built it/how its been built.

Many thanks for your posts. I understand your explanation fully, and appreciate the photos. Unfortunatley, mine is no longer a leak, more like a 'torrent'. When it was picked up by KTec racing, it was only a weep, and I would have happily lived with it until the clutch needed changing. However, unfortunatley over the past 8 weeks, it has got much much worse. If it continues at the same rate of deterioration I'd say another 3-4K miles, and it will almost unmanagable, hence why I have got warranty involved. spoke to very helpful 'Customer service manager' today at Ren UK, and also service guy at Renault Sport Basingstoke, car is in for 'inspection' on friday, inorder for claim to proceed. Hopefully will go smoothly.

Whilst I am at it, after reading your post about DMF failing, and you changing gearbox etc (nice thread by the way), I think if Ren Uk are doing under warranty, I will try and strike a deal to have my own (KTec) SMF and clutch fitted to avoid any future issues. I was going to do this in due course, but if someone else picks up the labour tab, seems silly not to.

Don't bother unless you like seeing the engine management fault light a lot. The smfs aren't without their (bigger imo) problems. The dmfs aren't as fragile as they are made out to be especially at your cars age.

This is no different to what happened for all Mégane Renaultsports and still happens with Clio Renaultsports. The engines are not built at Dieppe, but built elsewhere and then transported to Dieppe. However, they would not be sat around for a long time - as those who have visited Dieppe will testify - there is just not the room...

Ouija - I'm one of those customers. Paul looks after my car as if it were his own. V.happy with the service provided by SJ Cook. Dean is a very sensible, customer focused Service Manager as well - I'd suggest talking to them and keeping it "in the family" so to speak. They will be on your side.

That did sound like a bit of a "story" to me also tbh.

Just a quick update to all who have posted, and may help if any one searches in the future.

Car went to Martins in Basingstoke on Friday. They were very helpful, and are a 'Renaultsport' accredited dealer. guy who looked at leak says it is coming from the sump gasket. Apparently when the engines are built there are four beads of 'gasket sealant' that end up getting squeezed out when the bottom of the engine is assembled. He did not make it clear from where, but I will try and have a look when it is repaired. In short, he says that depending on who built the engine, when the sump is bolted to the engine, the four 'beads' or 'blobs' should be cut off flush with the sump mating face, to allow the gasket to seal properly. If not, the sump gasket weeps from these 'four problem areas'. I have rebuilt engines and many 'mechanical assemblies' and it is obvoius that a gasket has a much better chance of sealing the cleaner and more flush the mating faces are. However, apparently it's luck of the draw as to whether the engine builder bothers to check. This is their fix, and they have done it a number of cars. He said you 'can' get RMS leaks, and understands the afore mentioned 'theory' in my O/P, but in his first hand experience the more severe leaks are always the sump. Hopefully this will be the case. Will try and get some more info once rectified.
In addition will then post up results once a few miles under the belt.

Many thanks to all who have posted.

This was my original thought, redid mine with a new gasket and resealed. Still leaks, can only see how it goes though.

Bahnstormer: To answer your question, no the oil level is not dropping that much, but you only need a small amount of 'hot' oil to make the underside of the engine look a right mess. However since I've noticed it has got 'visually much worse' I'm leaving in the garage until sorted. (I don't want the hassle of cleaning everything up).
BMH: shame yours still leaks. Dealer seemed to think that their fix would do the job. Did you find any areas of sealant that were affecting the sump gasket from build, or was yours ok?

Cheers

Mine was leaking from both ends where the sealer it applied, the leak has stopped on the timing end where it was leaking before but not the drive end. Looking at it when I changed the flywheel its leaking out the sides of the no.1 bearing cap where again it has to be sealed. Bad initial build is whats caused it as you've been told there was very little silicone on mine, the ammount mine leaks is more an annoyance than a problem so it won't be getting "fixed" unless something major happens.
