Is it a big job to fix noisy lifters? I am tired of paying for repairs on this 220,000km vehicle. Now it is ticking real loud all the time.

Lifters can be easily replaced but it may be something else that is the problem. The first thing to do is get the oil pressure checked. If it's in the mid to high 20's then that is low.. Also get a compression test done. If both are low then the engine is wearing out and you would be chasing good money after bad by fixing the lifters.
A heavier oil like 15W-40 or 20W50 should quiet them down. You could also try an additive like Lucas. If you don't want to spend any large amount of money on the car it may be time to consider replacing it. Hope this helps.

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.

Lifters start to tick very loudy only after freeway driving but does not tick when I have a fresh oil change for at lease two to three weeks after freeway driving and the oil level is always at a safe


You cannot fix faulty lifters by changing the oil or using oil additives. The engine has to be repaired. If the lifters are ticking loudly bits of metal are being ground away and being circulated through your engine.

Using oil additives is a total waste of money and in fact is detrimentally affecting the lubrication job of the engine oil.

Why doesnt my 2006 dodge ram show codes for faulty lifter or or oil pressure. My truck makes a loud ticking sound coming from passenger side. sounds as if the lifters are knocking. took it in to the shop...


Most mechanical problems, such as noisy lifters or bearings, can't be detected by the engine controller and thus there won't be any codes set UNLESS the problem is causing a misfire or emission related concern. The ticking noise may well be a lifter even though none of them appear to be collapsed as the spring inside them will keep the lifter expanded but isnt' strong enough to keep them from being noisy when the lifter can no longer keep oil under pressure trapped inside. You may have to have someone do some further testing and inspecting to figure out exactly where the noise is coming from. Good luck, hope this helps!

Lifters keep ticking even though i have oil


Hi due to the age of the vehicle i would say you need the lifters replacing this is a big job and for the age of the car it may not be worth doing, as long as your car is running ok and not knocking i would leave it as it is.

to replace the lifters you have to remove the cam/s and have the timing belt changed and the timing set back up so it is quite a big job and will involve new gaskets and seals for the cam as well as new lifters and new timing belt, its a lot of money to spend and if you cant do the work yourself then its gona cost a lot in labour charges.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

Loud engine knock


I love these cars and have owned a 92 model from 98-09. These cars are infamous for lifter ticking noise. (look up lifter tick on youtube for sound comparison). Although this is not a problem, it is a big nuisance can be fixed by changing the lifters from a 97-99 model. These cars with high mileage also seem to be prone to engine rod knock. 3000gt's timing belts start slipping a tooth or so and the rods start to bang since the timing is off. These engines are interference motors, therefore if the timing is off and you drive around with messed up timing, your internals are all interrupted.(must be rebuilt)
If it is LOUD, I would say it is a rod knock. The best thing to do is add a can of thick oil(forget the name) and don't beat on it. This will reduce the noise alot. If you want to FIX the problem, you will need to rebuild.

A loud ticking noise?


No I would not chase to the pistons, these vehicle were very comon in creating HLA noise hydraulic lash adjusting valves, meaning the valves pump up with oil as the oil gets thinner they dont pump up as fast and create a very loud ticking noise, I would not express a great concern over simplicity, dodge was famous for this, they really were.

Engine ticking noise on cold starts


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

1988 Cherokee ticking


I had this with my old yj engine take the valve cover off and use a hammer or rod to press down on the rocker arm while running to find the noisy lifter. Also use the wire method as someone else rec. Check the rod bearings also. Mine ended up being the wrist pin in the number 6 cylinder after taking down the trans and removing the head 2 times hope this helps.

My friend just got a 1988 ford ranger  v6 2.9L and has a valve tap and was wondering what different kind of ways he could fix this


if its an ohv type the most common fault is that the oil ways to the rocker shafts become blocked
so get some flushing oil drain the oil and replace with the flushing oil and run for the time stayed on the can then Change to good quality oil and new filter
then remove the rocker covers and check and adjust the valve clearances
if its an ohc type its all hydraulic adjustment
you could try flushing as above but apart from that the only other way is to change the lifters and followers
hope this helps
