If you’re experiencing noisy lifters, a quick fix can be to clean the lifters and change their oil. However, if this doesn’t reduce or eliminate the noise, another option is to add a friction modifier such as Motor Medic 15.
The product comes in two forms: liquid and powder. The powder form is sprinkled into the oil and mixed thoroughly by turning on the engine while it runs for about three minutes. This process creates a thickened oil that’s been modified with the friction modifier.
The liquid form is sprayed into the oil and mixed thoroughly in the same way. The advantage of this method is that it doesn’t require a 3 minute engine run to create a friction modifier in the oil. However, it does use more product than does adding the powder to the oil.
The companies that make friction modifier usually recommend changing the oil when it reaches a specific viscosity (thickness). They also recommend changing the oil every 2,000 miles.
Friction modifiers can be a quick fix for some squeaky lifters, but if you’re not happy with the results, Motor Medic 15 is an effective addition to your maintenance program.
This simple device eliminates lifter noise. It’s nothing more than a short piece of rubber hose that has been slit open and placed over the end of the push rod. The lifter noise is greatly reduced or eliminated.
Does oil Change stop lifter noise?
If you are using a friction modifier or reducing the oil in your engine, are you sure that this is the best way to stop lifter noise? I have been using the product Motor Medic 15 for many years and have found it to be very effective. It’s a simple, inexpensive way to significantly improve how your engine is running and eliminate or reduce lifter noise. It’s quick and easy – you can spray the product into the oil, at anytime, without having to wait three minutes for the engine to warm up. I have found it to be the most cost effective way to eliminate lifter noise.
How to use liqui moly hydraulic lifter additive?
Motor Medic 15 is a friction modifier that is easily sprayed into the lubricant in your engine. If you want to use this product, it’s recommended that you change your fuel and oil (as well as the oil filter) at each oil change. Motor Medic is not recommended for use in vehicles with automatic transmissions.
- Add one ounce of product per quart of oil used.
- Use 1/2 cup per every 1000 miles traveled or 1 oz for every 1000 miles at an average speed of 60 mph.
To make it easier to calculate the amount of Motor Medic 15 you will need, sometimes a little math is required:
- If you are adding this product for the first time, use all 7.2 oz in one quart of oil to get good coverage of the bearings. This may seem like a lot but it works very well and does not harm the engine.
- Use 1/3 of a quart every 1000 miles for every three quarts in your crankcase.
Will synthetic oil quiet noisy lifters?
If the lifter noise is due to excessive clearance between the valves, I recommend waiting until you’re ready for a major service (like the original suggested time interval). At that time, replace all of the engine oil (including the filter) and check the valve clearance. If there is any significant wear on a valve, it will be obvious when you disassemble it and inspect it. If any valves are worn, they should be replaced. Try to find a used valve that matches the wear and tear of the valve that’s being replaced. Make sure you replace all of the oil seals when you rebuild the valve(s). Also, check your push rod length. If your engine uses an adjustable camshaft, be sure to adjust it after installing the new cam.
If there is no significant wear on any valve or if there are no valve problems, you can be reasonably sure that the excessive lifter noise was due to the oil. If you can check your oil level to see if the oil is below the level where it’s supposed to be, you can probably get rid of the noisy lifters without having to change your oil. I do not recommend that you install a new timing chain because this procedure will often result in excessive noise from the lifters.
Is stp oil treatment for noisy lifters works?
Stp Oil Treatment is a friction modifier that’s intended to reduce the amount of friction within the engine and increase its performance. It also reduces exhaust emissions. There are similar products on the market, so before using Stp or any other product, be sure you’re using one that has a high rating in your area.
Be sure to follow all of the application directions when using this product and be sure to change your fuel and oil at each service interval (including the oil filter). The vehicle should be operated for three minutes after the product is added to the oil. If you use this product, be sure to follow all of the instructions that are given in your owner’s manual.
Will stp engine stop lifter noise work?
If you have noisy lifters and want to eliminate them from your engine without having to spend money on a complete overhaul, I strongly recommend using Motor Medic 15. This product has been developed to eliminate excessive lifter noise from your engine. It’s very easy and quick to apply. It can be used in most any type of vehicle, including trucks, boats and recreational vehicles (RVs).
How to fix noisy lifters with a few drops of oil?
Here’s another method that you can try. It may be a few drops of oil over time, but it works and doesn’t involve any other products. Simply put a few drops of 3 in 1 Oil or motor oil into each lifter (both the push rod and the lifter itself). This will reduce the noise level significantly. It may take several weeks or months, but the noise level will gradually decrease until it is gone completely.
What is lifter noise in cars?
Lifters are small components located inside the engine that control the valve timing. They allow the valve opening and closing to be adjusted, so it’s possible for the valves to open slightly before they are supposed to. A lifter usually consists of a plunger (the part that controls the opening and closing of the valve) and a push rod (the part that operates the plunger). The noise lifters make is often due to excessive clearance between the valve and the lifter when they are about to open. When this happens, the oil in the engine makes a noise as it forces its way around the valve. This causes excessive wear on both parts. If it’s not too bad, you may only have to change your engine oil and filter every one or two months instead of at each service interval.
It’s important to know the main reasons for lifter noise as this will help you to make an informed decision on how to address the issue. If you are a newbie and this is your first time learning how to diagnose and fix car problems, I would suggest that you save yourself some time by checking out NAPA AUTO PARTS Technical Service Advisor. That way, you can avoid many of the annoying mistakes that newbies make when trying to fix their own car problems.
