Hi, could anyone help, my zafria gsi 2004 model has done 123.000 miles, suddenly had steam coming from bonnet/engine drove a little down road parked up quick, steam still coming. notice water leaking from underneath, oil check ok, all water gone and realised hose split from top of raidator to turbo. checked oil the following day no oil but no leaks anywhere. then noticed a little on header cover seal, replaced hose but engine still doesn't sound right and we have replaced oil and water and anti freeze. all filters were changed not long ago, oil pump seems fine but were not sure where to look now . please please any suggestions.
