All done, engine off, clutch off, flywheel off ( under the van ) crank seal wasn't the culprit. It was the gearbox main shaft seal. All back together now and no special tools needed.
Locked the flywheel with two bolts and a 3ft crowbar resting on a axle stand to clear the heat exchanger, span the gland nut out with a 3ft breaker bar. It was remarkably easy :s
If it wasn't the culprit why did you remove the flywheel? It'll probably leak now you've disturbed it
There was some oil there behind the lip of the flywheel, I wanted to be sure I didn't have two leaks. The gearbox main seal was very tired. The difference in the shaft play between the two was marked.
Would have been rude not to. Just back from a 15 mile round trip to my favourite riverside pub. She's dry as a bone underneath...... first time ever that.I recall! Fingers crossed. Clutch cable needs adjustment though, the bite is way to high, guess the cable needs slackening off.
