Well I bought the car on Monday and knew it had a small oil leak, previous owner thought it was coming from the rocker cover gasket. After degreasing the bottom of the engine and firing it up, discovered it's coming from a banjo fitting further on, passenger side of the car. Went out and bought some crush washers to replace the presumed bad ones only to discover that you can't get that bolt off without removing the timing cover, removing all the timing gears/belt and then removing the rear timing cover as well. Reassembled everything I pulled apart to get to that point and cracked a coke to have a think.
