Subject: Re: V12 Engine oil
Peter,
your car has very interesting features: the cotal box and a period radio.
concerning overheating and electric waterpump see also the post "V12 boiling". In short: I can recommend the electric waterpump which I installed in series to the original one. The correct long term cure would be to clean out the block and especiallly the waterways in the heads and to check the impeller of the original water pump.
