Is it normal when starting Jaguar S Type 2002 3 cc engine cold a ticking sound occurs until warm?

If your oil level is where it should be and If it just for a short time yes, because the oil has not reached the top of the engine from the sump thus causing the noise due to lack of lubrication... It should go away in a matter of a few seconds as soon as there is oil flowing over the valve train and chains. If it is lasting more like a minute i would get concerned something is blocking the oil pick up tube or the oil pump is faulty and oil is not getting up as fast as it should. Just about all cars make a short ticking noise in the begginig especially if they are high on miles... The joy of hydraulic lifters! As it's a 2002 model it has probably been serviced using synthetic oils. If it's done over 60K miles it's probably worth getting an engine flush at the next service. Over time the lifters get 'sticky'. It is good for freeing the sediments from the oil galleries and bearing surfaces too.
