They called back, mentioned there is a slight main seal oil leak.
That could have added to it but due the age age of the clutch being the original and 7 years old, myself and themselves have decided to press ahead with the clutch change. They said they could drive it to double check and better diagnose but ultimately with the symptoms it still seems the clutch perhaps aided by a little oil spray. |

A minor leak from the crankshaft main oil seal seems to be extremely common on the TDCi and, provided that it is minor, doesn't really seem to be an issue. It is not at all unusual to see a weep of oil from the bell-housing drain slot.
Provided the leak is small, it doesn't seem to get on the clutch. However, if you're having the clutch replaced anyway then I would suggest that it is worth getting the seal sorted at the same time since the additional cost will be relaatively small. |

the rear main oil seal is not like a normal double lipped oil seal , there a horrible hard plastic thing in moulded in a metal plate
like its been said quite often have a little oil round them anyway if the oil is running down then yes replace , but they are easy to cock up when fitting as the sealing edge has very little movement , you normally get a fitting tool (plastic ring) with a new seal to help lining it up very very rare oil will get on the clutch plate from a rear main seal did the clutch start slipping bad when it went ? |

The seal will be replaced.
It was slipping bad but intermittently , I didn't drive it to destruction / let it get to the stage that it failed completely. I think what they are saying is that the oil may have aided it in it's slipping, however due to the age it most likely needs replacing anyway. I was aware myself there was a slight leak but personally I think the clutch it's self is the issue. I've had some judder in 1st and reverse for a little while but not severe. I was just driving home one evening and there was lots of slip, I.e, in gear and no drive for a few secs until it gripped. I knew what the problem was hence why I didn't keep driving it, I do think it would have failed completely given enough time. I'm hoping it will be sorted by midweek latest, they had it in today and I think they are doing it tomorrow. Yet to hear about the flywheel which cost wise is what I'm a bit concerned about. BUT as mentioned before it's not something that you want opened up too often because the massive labour cost.. I knew straight away there was a big problem because like us all we know our Defenders so well. |

Anyway the jist of the convo was, they notified me of the slight leak and gave me two options:
1) A technician can drive it to see what happens and make a diagnosis of the outcome. 2) Press ahead with the clutch change anyway which seems most likely the issue. The issue was discussed a fair while and they asked me what the symptoms were and where it happened what gears etc. After that they tended to agree with me that it certainly was clutch slip, an issue that was nipped in the bud early so to speak before it got severe. Will report back soon. Thanks one again to Munch for the views and especially Blackwolf for the advice that had been most useful. |

I can relate to that 
With regards to the rear main oil seal, my 200Tdi has had a persistent leak from there ever since I got her and I had been waiting for the clutch to go so I could replace it. 200's are very prone to them going and so it made sense to do it while the clutch was being done. I would strongly recommend you doing it as apart from anything else - its already apart so the labour is effectively half a hour to whip the flywheel off, do the seal and reassemble, rather than half a hour to do that, along with hours spent dropping the box's and props etc If your not already having it done, also see if you can get the slave cylinder done at the same time as will give you further piece of mind. |

Heard back, flywheel is in good condition and not needed to be changed.
The slave cylinder and clutch fluid etc will be changed along with bearings and main oil seal. Rear diff leak also to be sorted at the same time. Inc new seal and oil etc. Have asked them to take some photos which should be good. I'm stung for £1300 though...
But I know it's sorted for a long time and the mileage I do the new clutch should sort me out for the next 4 years at least. The rear diff leak was meant to have been fixed anyway elsewhere. 
Expensive yes, but I now have peace of mind at least and know it's knowledgable mechanics. Splined shaft also greased and in good condition. Shall be glad to have it back, life with out a Defender is awful! |

they haven't got a choice weather to replace cyl or not as its a concentric bearing and cyl in one unit

Good News!! £1300 sounds about right to be honest but It doesn't take the sting out the tail 
At lest you have piece of mind and a years warranty on it
My flywheel has apparently arrived and should be being fitted as I type so all being well I should be reunited tonight! Can't Wait!  |

Munch - My apologies I don't know that, either way I'm glad the rear diff seal will be sorted too.

Here's the bill line up and parts fitted:
 Click image to enlarge Click image to enlarge Click image to enlarge As you can see the rear diff was leaking quite a bit, new flange fitted there also. Free health check done and brake fluid changed too I think. Could have had the service done too but the price would be a bit much in one go! It's a lot but 2yr parts guarantee and 1yr labour warrantee is very confidence inspiring, prices for parts are good IMO too especially seeing as this includes the rear diff leak too. Feeling a bit weird right now where it's new and the clutch bite is much lower, it's settled more as I've driven it and the brakes feel much improved too. Very pleased with the work and the drive despite the cost. |
