How to change timing chain

2.2 yes a ticking maybe it could be a pulley its under hood on passenger side

no required service on chain,unless it breaks or rattles.sure it's chain making noise?which pulley?

Not sure its either just saying could be I had a timing chain go out in another car doing 70 mph and bent my rods in engine it could be engine as well but hopefully not

ok,good luck with it.as long as you use the correct oil,and change it at regular intervals,most of the time you will send that car to the scrap yard,and timing chain/chains will still be good.should last the life of the car!
