Ok - secondhand head on, car running and has even moved 30 yards under it's own power However, there is a nasty droning noise from what appears to be the camshaft front bearing area (left hand) side :bang: Also the camshaft sprocket is getting rather hot. Could this be as simple as tapping the bearing out and replacing, or could the camshaft face itself be worn(?) I didn't consider specifically lubing these bearings when starting the car for the 1st time last week, however I suppose it could have been a pre-existing defect.
