It would appear that the leak is more than just the crankshaft seal. The brown resin in the picture below is where someone has tried to seal the leak in the past, George is going to clean this off and apply a sealant to see if this helps. Can only imagine this will be a short term fix and the engine case might need split. If so then this can be organised at a later date, keen to get the car home and work away at the deep clean.
I have started a list, not extensive but all that will be put right
Fuel gauge slow to register - only registered half way immediately after filling. Full the next morning. I have been told it might free itself up once it has been filled several times. Not sure how long it has been sitting.
