On the way to get the car tested we heard a bang and a taping/rattling noise from the left hand side of the engine. After Removing the covers we found out it was the Timing Chain, I removed the gearbox and Replaced both chains and tensions/rail, I Fitted the Cam locking plates and Lined it all up. I put the gearbox on and bolted up all the covers ect, Fitted the Top Chain Tensioner nut to keep the chain tight and the knocking stoped. i refitted all of the sensors and started her up, The knocking of the chain as stoped. But the engine is making a poping sound. Maybe "Knock" Were the plugs fires
