 Morning 
I rebuilt the engine about two years ago.   I have been living with an oil leak :-(   For the '3a I have a Mocal adaptor.  This image is off the website ( https://www.mocal.co.uk/products-spinofffilteradapters.html ) and is representational because the real one is the outer ring and the specific inner ring.  


Here are my questions :-) 

1. It appears to leak between the filter head and the block.  I checked the flatness of the filter head and made sure it is good.  Do I need to double the gasket thickness?   It was only a paper one.   2. The other leak is from the adaptor, mainly from the connection of the outer ring to the filter head.  Yes, the sealing rubber ring is there.  

Has anyone had issues with this adaptor?  And solved them?  Did I miss something stupid with the filter head to the block?
