With oil confirmed as leaking out of the rear main seal there was nothing for it other than taking it apart again. The sump came off with a little more resistances this time telling me that Id made a good seal last time.
The main cap was removed and seal inspected, nothing immediately showed up and the crank looked in good nick. I did notice some black crud on the crank, but wasn't sure what it was at that stage.Reviewing the photo I took showed that the flag on the seal was stressed and had started to break up, I also perceived I saw something on the actual sealing lip.
Removing the block side seal gave further clues, the flag was missing.
Using a feeler gauge I cleared out whatever was between the crank and block, basically bits of melted seal flag. Some of the bits had been engine side so had obviously travelled over the seal lip.
The crank was cleaned and a new seal fitted, this time with the flags removed! Seal clocked to separate block/cap join and seal join and a small dab of silicone on the block before the cap went down.
Job done, now to scrap off all the old sealant ready for sump install No. 3!!
