The specific vehicle or engine type is not really relevant to this particular problem, it's quite universal.
Hydraulic lifters "self adjust" to minimize the distance between the camshaft and the mechanisms that open the valves. When the distance is too great, the mechanism makes a loud tapping noise and can cause additional wear on the camshaft and lifter surfaces. When a hydraulic lifter becomes clogged with sludge or otherwise becomes unable to self adjust, the lifter colapses and the valve mechanism starts to make noise. The problem is often the result of poor engine maintenance, specifically poor oil change history.
Replacing the cam and lifters can be expensive. Before you do that, try an engine cleaning additive. It's worth the effort since they are usually quite cheap. There are several that claim to free stuck lifters but if there is much damage it won't help much.
If it DOES help, make sure you change the oil and filter often and use a good grade of oil.
AnswerSticking lifters in a car is like a clogged artery in your body; the both can happen over time and they are hard to reverse, and surgery/repair is expensive!I agree with the above; here is what to do: purchase a quart of RISLONE oil detergent along with oil and filter. The RISLONE takes the place of one quart of oil. Change your oil using these items.Run this no more than 1000 miles and do it again. And again. By the third time you will notice a significant decrease in the noise or it may be gone altogether.I have done this a number of times before and it will work in all but the most extreme cases.Once the noise has ceased, make it a practice to change your oil and filter at 2500 miles to keep the lifters clean.It is a lot cheaper then the labor to tear your motor apart! Good luck.
my 2001 ford windstar will turn over and make a clanking noise like metal to metal is hitting? Just replaced the starter and had the battery checked what would be the problem?
What would cause a grinding noise after a tire is replaced and the brakes are not worn?
Collapsed hydraulic valve lifter? Rocker arm (valves) need adjusting?
from which part of your engine is the ticking noise coming from. if is the TOP it would most likely be lifter noise.try using a thicker oil.
A tapping noise is generally the result of a bad hydraulic lifter, plugged oil passage to the lifter, or bad tappets. Sometimes just changing to lower viscosity high detergent oil will cure it. Or "Any automotive oil additive with the word MIRACLE in it".
Diod you check front brake pads
If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do
if its a tick not a knock, its probably lifter noise. its not too terrible, once the weather warms up, i would recommend getting some thicker oil, if it fixes it, then im probably right.
A ticking or clicking sound is probably lifter noise, the valves need adjusting
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
sounds like a bad lifter, let the dealer fix it as it's under warranty.
It would depend on how strong the weight lifter is.
