Hi George, yes tried that, they were loose, but the damage must have been done to the old seal as its still weeping on the o/s bank.
'Rangerovering' really appriciate the advise, I am very tempted to do this myself, my only concern is the stuff I have to remove from the top of the engine to get to the covers... Its a 2001 model year with the 'thor'? engine.. I can see the throtle body has a water circut, which will all have to be removed, and I will have the swirling like air inlets to take off also... is this all stright forward or are there allsorts of other things I need to worry about. Dont want to mess this up as with wife will kill me... its her car. Many thanks Graham
