Rattling in the top end

[SeatLeon5548]

Towed my car and started it once we stopped the engine sounded like a bunch of empty bottles being hit together really loud rattling, prior to this all I did was change the turbo, put new seals in the Injectors, new fuel filter and changed the fuel lines the car has drove with plenty of power right up to 110 further of I ran out of road.

Anyone any solutions
