Bähhh
habe jetzt im Grünen Forum dazu was gefunden - jetzt bin ich natürlich gekniffen da ich
1) schon alles zusammengebaut habe und
2) Dieses doofe Spezialwerkzeug nicht habe
3) das nicht im Handbuch gefunden habe so ein Mist!
Was tun?

There is a very precise method, how to fit a rear crank shaft seal into an XK-motor of Jaguar. You have to follow up the procedure step by step in order to have a non-dripping seal. Probably the most frequent problem with the oil dripping in XK-motors has to do with unproper or none sizing of the rope seals before fitting the crank shaft into the motor block! If you do not size the seal properly, you will burn the seal at the first startup of the Engine!!!! And the motor will 100 % sure drip oil!
Some one here already said, do not cut the seal halfs and he is absolutely right, they are of proper length and you will see this if you follow the proper procedure to size the seal in!
I did this according to instructions I found a) in the e-type repair manual b) in an article in the Jaguar Enthusiast's magazine and I will try to cover these instructions here as good as I can:
1. take the rope seal parts (2 pcs) and put them into motor oil for 24 hours to impregnate them well with oil (Engländer nennen das hier als marinieren von seals
)
2. install the rope seal parts into the grooves within the rope seal carrier within the back bearing house (the ring type thing that is bolted later into the motor block), make sure the seal ends fit against each other and don't cut the seals shorter, I repeat do not cut the seals shorter! (you will now notice that no way the crank shaft will fit into this as the diameter of the seals inner circle is much smaller still than the diameter of the crank shaft
3. install the seal with it's carrier to the motorblock without crank shaft
4. now you need to have the correct so called Churchill tool to do the sizing of the seal. The tool is a cone with one end smaller than the diameter of crank shaft and ending in the other end into the same diameter as the crank shaft has. at the bigger diameter end there is a handle throuh the whole thing so that you can turn the tool within the seal. As the correct tool is not that easy to find (one can rent this from Jaguar Enthusiast's club but probably only within UK), I also made the tool myself from a piece of aluminium.
5. put the tools smaller diameter end within the installed seal and start turning the tool slowly counter clock wise at the same time pushing the tool against the seal slightly... keep on turning for 1-1,5 hours, you should not rush and do this too fast, other wise the end result will not be good! So take your time, do not use too much force and best is to have your friend with you, because turhing the device for 1 hour is quite a job. So keep on turning and same time pushing the tool within the seal until it is fully in and the end of the tool (with the same diameter of the crank shaft ) is inside the seal... now the sizing is ready!
6. remove the tool and install the crank shaft (for this you need to take the seal carrier apart from motorblock again)
If you take your time and do the sizing correctly, your Engine will not drop from the back seal for next 30 to 40 000 km's... at the end all XK motors drip anyway
If this procedure sounds too difficult for you or you cannot get the right tool for sizing I suggest you find a garage that knows XK-motors and let them do the job for you!
