what will quite noisy valve lifters?

Answer 1

That depends on exactly what caused them to be noisy. I am assuming you are talking about hydraulic lifters, rather than mechanical (solid) lifters. Generally, hydraulic lifters start "tapping" if they are collapsed, either due to wear or low oil pressure. If the engine is low on oil, and the lifters have been making noise only a very short time, adding oil may help (do not overfill). Other than that, replacing the lifters is the only real cure. Of course, if the camshaft is also excessively worn, this would contribute to the situation, and replacement of the camshaft and lifters would be necessary. I'm sure you will get some answers advising you to use STP or some other "mechanic in a can," but that won't really cure the problem.

Depending on what engine you have, you may be able to adjust the lifters. This involves resetting the preload on the lifters by adjusting the rocker arms, thereby increasing or decreasing the pressure between the lifters and the pushrods. To do this, you need to reference the maintenance manual for your vehicle and follow the procedures shown in it.

Answer 3

this problem may require more information but i will try and give u sum answers.there are two diffrent types of lifters one is a solid lifter and the other is a hydraulic lifter if u have a solid lifter set up in your engine and u have noisy tappets then u will need to have your valve clearences adjusted to there correct spec .THis is not a genral job and u may need to c ur mechanic if u havnt done this before.On the other hand if u have hydraulic lifters there r twothings that can cause noise.Has ur car been regurly serviced lack of oil changes will gum lifters up so they dont operate properly and create excessive valve clearences best way to overcome this is to put a bottle of engine oil flush in ur car run it 4 abouty 20 mins then drop the oil and change it with fresh stuff this may fix the prob .hope this helps more information on the car u r talking bout could lead to a more direct solution a wild guess i bet its a hyundai

All Escorts use an overhead camshaft ( double overhead for the 1.6 16v ) with hydraulic lifters (or tappets). These are always prone to becoming noisy. Has the oil been replaced recently? I recommend an oil change + filter. Oil for this car is semi synthetic 5w/30. I would buy Comma. I would also consider using an oil additive specifically made to reduce noise. These are available in most decent car parts and accessory shops. Bear in mind that it is normal for the lifters to be noisy when the engine is cold.

RE:

Answer 6

year and Model of Car ???

Guessing... I would change the Oil and Filter 1st

Next is Q and A...
When did it start being noisy?
Has it been always there?
Was it over heated?

Off the question... All oil filters have a check valve, even just a simple spring over a flat piece of metal. This is if the filter gets stopped up with sludge and etc... Mazda B2200 and some honda's have a double check valve. So if the person changing it puts the wrong or fram filter on it lifter tick more than they should...

Hope you get the answer your looking for...

Answer 7

You people really need to include what make, model, year and other info before asking mechanical questions!
.
I'm assuming you own a car?
Or is it a lawn mower?
When did you start noticing the noise?
When is it the loudest?
Your car engine will have either mechanical or hydralic lifters, that in turn opperate tappets that open and close the valves.
They can be adjusted by someone who knows how,
If you haven't changed your engine oil and filter in a year, this might be a good time to do so,

Answer 8

A major cause of lifter noise is people listening to idiots tell them to use thicker oil. Too thick oil won't pump up the lifters fast enough. Thick oil makes your oil pressure gauge read higher, but that's because it's harder to pump. You actually wind up getting less oil in places you need it. Like lifters. Or, the lifters are just worn out and leaking down at low speeds.

Answer 9

Are you using the right Octane fuel for your car, does it just do it under a load? Depending what make or model you have, lifter chatter can be caused by several things. If it is an older model you can pull the valve covers off and set them yourself if you are so inclined and know the proper procedure, otherwise let a certified Mech. look at it and determin the right fix.
