I have never seen any ball end bigger than a 6 mm break the ball off. For sure have the ball end wrench as perpendicular as possible is desirable. Just because the wrench is bigger doesn't mean you should hang all your weight on the "cheater" pipe. I couldn't help but notice the 8.8 grade marking on the bolt picture. Try to get a 12.9 and make certain it's the correct length.

Best of luck to ya'.

 

That is an interesting mix of S3 and S4 pieces! S4 intake/valve covers/harmonic balancer, S3 fuel inlet hardline/brackets/rails/covers/ignition wires. Does it have 24 pound or 19 pound injectors? Which brains does it have?


How much 'power' do you get from your power brakes? The venturi is backwards. Maybe it makes no difference (?)

EDIT: Oh yeah:
