How to change valve lifter

It may be worn out valve lifters that are inside the engine. If you have more than 6,000 miles on the oil, valve lifters could run noisier. Changing to a high mileage type of motor oil may quite down the valve lifters noise somewhat. Synthetic oil used during the summer months could make it noisier too. If you can hear the noise while driving the car, it is not normal. Upon acceleration, if it gets noisier, you will be needing a valve job in the not to distant future.

Hi, the lifters can be noisy of luck of oil. Check what oil should be used on your car specification. If they still noisy that mean you need to replace them.

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.

sounds like lifters noisy. have you checked the oil level and a good oil change. to see if you have bad lifter you will have to take the valve cover off

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.

you could need valve clearance adjustment or need oil and filter change oil is dirty.causing dirt particles stop up hydralic lifter bleeder holes stopping lifters from pumping oil.or lifters worn out.and oil passages in engine block restricted with sludge.

Sorry but there is no valve adjustment with hydraulic lifters - can turn the lifter upside down fill with oil - let sit for a while and then tap on the lifters to see if they make noise - if noisy replace.  Camshaft may be worn on the lobes or may have jumped timing if belt.

a lifter or valve would not cause a misfire. look at the wires and plug again

if its an ohv type the most common fault is that the oil ways to the rocker shafts become blocked
so get some flushing oil drain the oil and replace with the flushing oil and run for the time stayed on the can then Change to good quality oil and new filter
then remove the rocker covers and check and adjust the valve clearances
if its an ohc type its all hydraulic adjustment
you could try flushing as above but apart from that the only other way is to change the lifters and followers
hope this helps

The camshaft may be worn or the lifters .that explains the missing when you run it at operating temp.By the description of the oil. the reasomn the canmshaft wore out and the valve lifters is because the oil was not changed on a regular basis.
