98 dodge caravan 3 liter ticks on cold start,

SOUNDS LIKE YOU HAVE STICKY LASH ADJUSTER(LIFTER)..MANY MILES ON IT?HAVE YOU BEEN GOOD TO CHANGE OIL AND FILTER?TRY CHANGING THE OIL AND FILTER AND ADDING AN OIL SUPPLEMENT ..IF THIS DOESN'T WORK,YOU WILL HAVE TO ISOLATE WHICH BANK OF ENGINE NOISE IS COMING FROM,REMOVE VALVE COVER AND YOU CAN TO SEE WHICH ONE(S) ARE MAKING NOISE..PUSH DOWN ON EACH ROCKER ARM..A BAD ONE WILL BE SOFT..A GOOD ONE WILL BE HARD..NO LASH..TO REPLACE..YOU REMOVE ROCKER SHAFT BOLTS AND ROCKER SHAFTS..YOU CAN PURCHASE ONLY THE ONE(S) YOU NEED..BE CAREFUL WHEN YOU REMOVE ROCKER SHAFTS..THE LIFTERS CAN FALL OUT..GET A STICKY GREASE TO HOLD THEM IN ROCKER ARMS DURING REASSEMBLY..I HOPE THIS HELPS
