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
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
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.
It would depend on how strong the weight lifter is.
A ticking or clicking sound is probably lifter noise, the valves need adjusting
sounds like a bad lifter, let the dealer fix it as it's under warranty.
push rod or tap its. It would be a cam lobe that moves the lifter.
your barrins in the wheels
that means you need more oil. it could also be a sticky lifter or slightly bent push rod or even the tappets out of adjustment
Not that familiar with Jeeps, but you could have a collapsed lifter, or you might have a rocker arm out of adjustment.
the most common thing is a faulty multifunction switch.
My '91 has a new engine, but they used the old head without a rebuild. I had some lifter noise, which is normal with the 4.0. Recently it became a little noisier, and I drained a pint of oil, replacing it with a pint of Marvel Mystery Oil. Within 30 miles it was much quieter. From what I understand, MMO has solvents that clean out the gunk that cleans out the passageways in the lifters allowing them to maintain pressure. I would bet that almost any lifter solvent/cleaner would do the same thing. I use MMO because it's worked for me before.
I would suggest a second opinion...Try another mechanic.
If a lifter is stuck in the lifter bore and won't move, it has probably ruined the cam. The procedure would be to install a new cam and lifters.
is the noise coming from the new fuel pump (in the tank)? if so the new fuel pump is bad
that warning noise is telling you your brake pads need to be replaced as soon as possible, plus i would replace them very quickly anyway cause the noise is annoying
Erm yes that should be your brake pads, you should get them replaced quick or the damage will be even worse! Or Could be your engine, so i would get them both replaced promptly.
I had a similar experience with my Windstar - lots of pad material left, but still grinding after new pads & shoes. Turns out the rotors were bad. :( Btw, I just replaced the rotors without finding out if a simple turning would have eliminated the grinding.
It is cheaper than replacing the lifter
