Most probably the lifter has gone bad, but if it is a LOUD knocking sound, it is possible one of the crankshaft / connecting rod bearings has been damaged. Usually a bad valve gives more of a "clicking" sound.
A bad camshaft lobe will also cause a "knocking" sound usually with an engine with high mileage.
A lifter problem can only be fixed by changing the lifter. You might as well change all of them because it is just as easy since you have already had to take the heads off to get at the noisy lifter. While you are at it, get the heads reconditioned or a valve job. More than likely the oil was not changed as often as it should have been. Dirty oil works like sand paper on the valve stems.
Hi , usually a knocking / pinging from the valve cover indicates a lifter tapping. Could be worn out or just worn. Do you change your oil every 3000 with high quality oil? (I always have used valvoline standard with outstanding results) Dirty oil and filter and or incorect weight oil and or using synthetic oil in older cars can result in lifters tapping. If your oil is under 2000 miles since last change and you used a high quality oil (watch who changes your oil, some places use inferior oil because its cheaper) you can buy a pint of oil treatment formula to quiet noisy lifters to coat the lifter and quiet it down. It is a sign of engine wear, but one lifter tapping a bit wont really hurt your engine mechanically. If they all get noisy, time for a valve job. Root cause is wear due to insufficient lubrication. The lifters on newer cars are all hydraulic and they self adjust. No manual adjustment is possible. Bottom line: keep your oil changed regularly using a high quality non-synthetic oil for your 1999 vehicle.

lifters tick and noise is upper end of engine if lifters are making noise could be from a bad valve,bad lifter ,push rod ,oil pressure,rocker arm - need to take do compression test find out if valve problem and which cylinder is problem also take off valve cover and check for proper oiling of valve head and look to see if and are damaged or loose-------a knocking sound usually comes from lower end of engine,rod knock etc.and thats usually rebuild of engine
