    my original engine needs an overhaul, weeping oil, compression down etc. 140k miles. I got hold of a refurb engine at the right price so I'm doing an engine swap out and while at it figured I'd do the clutch as well (before I stopped driving it the pedal was out near end and it had started slipping a bit in 3rd) I took the gearbox out as well for a good look too so have the advantage of having all out on the bench.
    have the original clutch and flywheel off now, slightly puzzled in that I expected there to be a good bit of wear on the clutch but only about a mil in the difference than the new one?? except it is mucky and a wee bit oily. also noted inside of gearbox casing oily. Its hard to tell but I think the gearbox casing is sound (as in the seals/gaskets are ok) and I'm betting the oilyness down to the engine weepage on the timing belt side getting in there over time.
    I presume the clutch and the casing should allways be dry and free of any oily residue generally? might the oilyness have caused the the clutch to start slipping in 3rd? or might there be any other reason?
    Although I reckon the box is actually ok/dry should I do the oil seals anyway or leave alone?

    Any other hints also welcome, thanks!

    Only seeing this now, how did you get on with it afterwards?

    The clutch release bearing rod goes through the input shaft and this seal can go causing oil to leak onto the clutch, failing that if the oil is very dirty its probably the crankshaft oil seal behind the flywheel.

    Where abouts are you based btw?

    You should register on Autostadt.ie its a new German car forum, plenty of info/tips there.

    yeah, was grand in the end thanks for the reply
    (sometimes you just have to just DO something instead of thinking about it, y'know? it wasn't a bad job very straight really. and I didn't need any fancy tools for centering up the clutch or anything..got a brill hint off one of the forums to just use the tail end of the wheel nut breaker with an extra bit of masking tape t build out to a snug fit which worked first time no bother
    there was a fair bit of play on that seal on the gearbox. also found the rod was a couple of mil shorter than it's supposed to be so did and I it and the bearing too.....
    I think the original oilyness problem was defo the crank seal though. I broke the engine up afterwards with the intention of a rebuild but found that one of the shims that I'd say stops lateral movement of the crank was damaged and in the sump and there's a bit of scoring visible...have been told that in this case I may as well find a skip and go look for a better bottom end. it makes some sense to me that this might have been the problem all along...its a pity but it was great to finally put a face to the problem!
