Arghhhh now I will have to take it back off to check!!!!
Then enjun internal mices are harder to find on account of them not squeaking so much, what with all that oil!
Timing chest "rear" seal now also fitted!
Next step water pump fitment.
I am going to see the "Bentley boys" before trying the other sleeve on the harmonic balancer. They are very very skilled Bentley and Rolls Royce restorers and will likely be able to tell me why attempt 1 was a failure. Will also hopefully let me borrow lathe to mark correct timing on "new" HB.
