I looked to buy a 4x4 cossie yesterday j plate 1991.Anyway the car hasn't been started for a week or so,the battery had been disconnected.The car started with no problem,nice an quiet,after a minute or so the tappets started getting a little noisy again for a minute or2,then it cleared and the car was nice and quiet again.Does this mean the tappets are passed their best and need replacing?What sort of cost would this occur and can you recommend a good quality tappets set to replace them with please.Will this happen every time you start the car from cold or is it possibly because the car has been standing and not started for a week or so?Please help.
