Hi my local garage looked at it! There was sump damage on the car! changed the sump, there was no engine oil in the car. engine wouldnt start until it was topped up with oil! this is where the damage has happened? Car drives but Engine noisey and lack of power!! at first we thought it was the clutch? clutch and flywheel changed, still getting the knocking, rattle sound, checked gearbox, A OK!! started car without gearbox noise still there, had the car up on a hydraulic lift thingy to listen underneath and can hear the noise coming from under the flywheel area!
