i changed the oil on my 82 double six before laying it up for the winter in november 09, i changed the filter and re-filled the sump with morris lubricants storage oil and ran on fast idle for 15 mins before shutting down for the winter period,i am planning on putting the old girl back on the road in march (if it ever stops snowing up here in perth!!),i read ken jenkins article with interest in the jec feb magazine about introducing 15 to 20lbs of air pressure through the dipstick tube after first blanking off the breather,but he goes on to say that on the v12 the pump does not always prime in every case,any more advice from you long term v12 owners out there?!.
cheers ian
(ps the car has not been started at all in the lay up period)
