SOURCE: The lifters tick at start up and stop when it is

Yes, that means when they are ticking they havent gotten the oil to the top of the engine yet. They stop ticking cause the lubrication has reached the top of the engine, and doing its job....

SOURCE: Loud ticking noise on startup

I would have you oil pressure checked. The oil pump or bearings could be going out. The lifter noise on this car usually will go away faster then 5 minutes. I think the noise is lasting a little to long.

If the preceding check indicates the valve mechanism is abnormally noisy, remove the rocker arm covers so that the various conditions that cause noise may be checked. A piece of heater hose of convenient length may be used to pick out the particular valves or valve train components that are causing abnormal noise. With the engine running at a speed where the noise is pronounced, hold one end or hose to an ear and hold other end about 1/2" from point of contact between rocker arm and valve stem. Mark or record the noisy valves for investigation of following causes.

  1. Excessive Oil In Crankcase. Crankcase oil level high enough to allow the crankshaft to churn the oil will cause air bubbles in the lubricating system. Air bubbles entering the hydraulic lifters will cause erratic operation resulting in excessive lash in the valve train. Locate and correct cause of high oil level, then run engine long enough to expel air from system.
  2. Sticking, Warped or Eccentric Valves, Worn Guides. Sticking valves will cause irregular engine operation or missing on a low speed pull and will usually cause intermittent noise. Pour penetrating oil over the valve spring cap and allow it to drain down the valve stem. Apply pressure to the one side of the valve spring and then the other, and then rotate the valve spring about 1/2 turn. If these operations affect the valve noise, it may be assumed that valves should be reconditioned.
  3. Worn or scored parts in the valve train. Inspect rocker arms, push rod ends for scoring. Check for bent push rods. Check valve lifters and camshaft surfaces for scoring. Replace faulty parts.
  4. Valves and seats cut down excessively. Noisy and improper valve action will result if a valve and its seat have been refinished enough to raise the end of the valve stem approximately .050" above normal position. In this case it will be necessary to grind off the end of the valve stem or replace parts. The normal height of the valve stem above the valve spring seat is 1.933 inches, for 350 cu. in. engines and 2.082 inches for 455 cu. in. engines.
  5. Faulty Hydraulic Valve Lifters. If the preceding suggestions do not reveal the cause of noisy valve action, check operation of valve lifters as described in paragraph 60-33, subparagraph c.

SOURCE: What does it mean when the lifters are making

As the crank shaft turns raising and lowering the pistons the Cam shaft turns along with it. The Cam shaft has raised lobs the push the rocker (kind of like a Sea Saw) which in turn pushes the lifter down. This opens and closes the valves. All of this is to set up the right conditions for the piston to deliver a power stroke. When the rocker or lifters become warn gaps between the rocker and the lifter become larger. The tapping noise comes from the lifter making contact with the lifter as it closes the small gap that was created from the wear. There are also other reasons for lifter notice as well. Not changing the oil can cause built up of sludge that can result in a lifter collapsing causing noise.

You should also be aware that the 2000 Buick Century with the 3.1 L engine was known for a condition called "piston slap". This was built into the design of the engine and can easily be confused with lifters tapping. If what is being heard is piston slap you should only here it when the engine is first started and it would go away when the engine warms up.

I hope this helped. God Bless.

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.

A ticking sound on a 06 ford f150 super crew 5.4L

Ticking sound could be coming from a Coil-on-Plug, or a pcv valve, or (hope it's not) a valve lifter which could be sticking. Sticking lifter noise often disappears when rpm's change, or the noise comes & goes. try changing the motor oil & filter right after adding an Engine-Flush Treatment to the motor oil, running the engine for 10 minutes at idle with treatment added to the oil, then draining the oil & changing filter while oil is still very hot. That last part is very important, so be careful not to burn your hands - be careful. -- The sticking lifter is a likely cause if motor oil has not been changed at frequent intervals in the past (every 3-4K miles) -- dirty oil causes sticking lifters.

How do i adjust valves on a 4.3 vortec tbi motor

The 4.3 liter vortex uses a hydraulic lifter. There is no valve adjustment. If you hear a lifter tick than there is either a bad lifter or something broken in the valve train. Something yo can try for a sticky lifter is add 1/2 a can of seafoam motor tune the oil. Start the engine and let it run until the noise goes away. Then change the oil. If the noise doesn't go away than you have bigger issues. I have yet for the seafoam to not fix a sticky lifter especial in the 4.3 liter which we see quite often.

A ticking noise in motor

Usally it's a stuck or colasped lifter. You can check your local parts store for oil additives that may unstick the lifters, often you'll have to replace the lifters. Also check oil level and oil pressure.

Ticking noise in engine

It sounds like the lifters are still sticking. Change your oil/filter then after 500 miles change it again. Since motor oil has a mild detergents, a couple of changes should hopefully remove any buildup from around the lifters. Do not use "motor flush". Even though your engine is fairly new, it may remove too much buildup and flush it onto your crankshaft bearings. You may try some marvel mystery oil also and I've heard seafoam does a good job, if you can find it. Mine started ticking after using one of the super thick oil additives. I'm still trying to flush that stuff out.
