Not sure if i posted about this before but my V8 Disco (3.9Efi) smelt badly of hot oil 'tother day. A quick nose under the bonnet revealed oil on the block coming from the rocker cover join. Tightened the bolts for each cover (6 of them were very loose indeed) over a month ago. How can i prevent the bolts from coming undone/looseing, or is this a usual problem on this type of engine?.
