I have a 99 bravada it burns oil so i have to keep adding oil now its making a lifter noise comes and goes usually quiet at a cold start loud when warmed up its almost like it gets stuck or something?


Hydraulic lifters do suffer problems that cause noise sometimes, often caused by a buildup of gum and carbon. There are a range of proprietary additives to help combat such things.

If the noise gets louder and more harsh as the engine speed increases it could be caused by a worn cam lobe. If the noise fluctuates it could be caused by a worn lifter and bore. In some designs the lifter rotates due to an offcentre contact with the cam...

Slight tapping noise from engine when accelerating when engine is warm.Started about 3 days ago but hasnt got any worse.Doesnt do it when cold.


tap usually associated with lifters when vehicle warms up oil thins out and a bad or worn lifter will make a tapping noise --other oil level low --oil needs changing --low level will starve rockers/push rods/and lifters which will also cause tap ---damaged /dirty{sludge oil can cause same problems

What will be the problem if i have a taping noise when i start my car until it gets warm mitsubishi 380


A tapping noise that starts out cold and goes away when warm is usually caused by a valve lifter inside the engine. The lifter may be worn/leaking down and will be noisy until it fills with oil pressure. You can try an oil additive ( Lucas Oil Additive ) available at most part stores works very well with noisy lifters. Another noise that can happen cold and go away when warm is an exhaust manifold leak. However, this is normally a ticking type sound rather than a tapping sound.

How do i fix my 2001 740i bmw it makes a ticking sound win idleing


could possibly be a lifter tapping (Ticking) ,depending on how many miles the vehicle has on it might be time for lifters to be adjusted,most foreign overhead cam engines must have lifters adjuster periodically ,if you turn on the air its puts more of a load on the engine causing a louder sound (also check oil level an engine low on oil will start to tick too.. the more wear the engine gets the looser the lifters can get over time ,look in your service manual if you have one and see what the intervals are on lifter adjustment this can give you an idea.
possible only if
the ticking sound is coming from the top of the engine usually comes from under the vavle covers where the lifters are located,

Taping in a 1999 firebird


by tapping do u mean ticking as if you were listening to an old sowing machine?not to worry very comon with these cars i know i had one do to engine design it is comon for these motors to make noise like that they use differnt kinds of metals in this motor an shaved parts to meet emmisions the noise should get quit after it has warmed up why u might ask because when motor is cold the internals in the engine are one shape as it heats up it either expands or contracts to take up any play internal parts like i said very common and does not effect the performance of this vehicle however if after warm up sound remains or gets louder or makes noise with acceleration could be more severe i fixed one were a lifter collapsed an just needed replacement if you are concerned and have no automotive knowledge have a dealer check it over .but go to more than one garage lots of scam garages out there just remember these motors are aluminum and very sensetive. fyi cam an lifter will only cost from 800-1500 but if motor blows your looking at 5000 easy

Possible lifter knock, been very cold here in midwest. runs fine in cold weather. warming up and i get a knock from engine. removed oil cap and does not really get louder ?? does go away and comes bac


Your hearing lifter noise common in most cars in cold weather I have a 2001 sc1 same engine as yours here's how to get rid of that ticking sound go buy a quart of Lucas synthetic motor treatment change your oil and leave it 1 quart low add the Lucas synthetic oil stabilizer within 1 week you will not hear the noise agian reason your hearing the noise is there's no oil at the top of the engine on a cold start oil when cold is thicker hints why your noise in your engine what Lucas does is eliminate the dry start by the way my engine has 288,000 and does not use a drop of oil after you use this product you should use it every oil change you will see your car will thank you regards Chris

Lifter noise lexus ls430 2001


Lifter noise(s) can be a combination of things........ 1. High mileage on engine. 2. Not using the correct oil. 3. Lots of sludge build up in motor due to lack of oil changes and the quality of oil that you are using. Hydraulic lifters rarely fail but it does happen, given the conditions on how the car was maintained. I can offer you a solution but no guarantees on what might quiet this lifter down. It's a 50/50 chance. On your next oil change, I would recommend taking your vehicle to a facility that sells BG products. It's a company that formulates chemicals that have great cleaning properties to your fuel system and oil lubricating systems in your engine and at the same time, it is safe on all rubber seals in your engine. (Especially Higher Milage Vehicles) Ask for BG MOA to be added in you next oil change or if you do your own oil changes, you can find this product on line and can purchase from there. What the BG MOA does, it helps break up sludge and build up on the inside of your engine and helps to free up your valves, piston rings and noisy lifter(s). Hydraulic lifter(s) tend to make noise when they can't sufficiently pump up with oil due to sludge and build up blocking the oil inlet passage. Worn lifters on cold start up may be very noticeable but eventually the ticking goes away after engine warms up and the hydraulic lifter(s) had time to pump up. Make sure that you don't have a exhaust manifold leaking as well due to a crack or a failing exhaust manifold gasket. This can also emit a ticking noise in which can be misdiagnosed for a ticking lifter. A leaking exhaust manifold can usually be identified by the ticking noise getting louder and faster when accelerating and quieter and slower when decelerating. Ticking noise is loud on cold start ups but not noticeable at all when engine is at operating temperature. Hope this will help you out.

Ticking noice gets louder when warm


If it goes tick, tick, tick, you might be low on oil or your lifters may be pecking. It is usually a sign of low oil or engine damage in the block. Check your fluid first. It may be a quart or two low. If not, it will need fixed eventually. That is up to you.

It does sound like a lifter tick. You can have fine oil pressure right up till the lifter blows a hole in your pan. The fact that it gets louder as you accelerate really makes me think that it could be the problem. Does it get louder as the vehicle warms. If so you might have a big problem. Your air problem maybe blow bye from improper installation of pistons. Not to sure bout that but the tick I would worry about.

Engine ticking noise on cold starts


Sounds like a stuck valve lifter. I'd use some oil additive for unsticking lifters.
