What’s The Reason For Glitter In Oil After Rebuild?

Did you get metallic particles or glitter in oil after the rebuild? It can be happening for various reasons. This is the guide to find the causes and solutions and more information. As we know, engine oil helps lubricate engines’ different parts and increases important components’ life.

Sometimes, you can see the glitter in the engine oil. Well, oil glitter is metal flakes from machine parts. Due to insufficient oil, it can’t lubricate your engine parts, and various metal elements rub against each other.

Reason For Glitter In Oil

Glitter In Oil After Rebuild, Reasons:

Actually, gold glitter in oil after rebuilding is usually not good. Let’s know the reason for it:

Engine Wear and Tear

Several components in your engine experience significant wear, like cylinder lines, main bearings, cams, wrist pins, and rod eyes. Engine wear always occurs over time from the wear of metal elements. As the metal wears, a small amount will penetrate the oil.

If metal fails to make your oil look glittery from flake, you may have components that are wearing more. After that, they fill your oil with metal.

Using a New Vehicle

Oil glitter in oil on the new engine is normal because the engine is new. If you are driving a new vehicle, it is common to see oil glitter. Slightly cracks and fine particles become suspended in the oil on your new engine. But if you use your vehicle for many years and see the glitter in the oil, that means there is a problem.

The Oil Filter Is Faulty

An oil filter is responsible for seeing these metal particles in oils. But it can’t catch all metal debris, especially when it’s extremely dirty or blocked. That’s why you see metal shavings floating in engine oil. So, it’s best to check the oil filter regularly and, if necessary, replace it.

Oil Pump Malfunction

The primary duty of the oil pump is to circulate the oil to the engine’s various parts. But it may malfunction over time, and oil might only reach some elements. Due to insufficient lubrication, metal parts will rub against each other, so you get glitter in the oil.

Low Oil Pressure

If thrust bearing or rod wear out, the engine can’t tolerate them. Tolerance is essential for smooth engine operation. But when they are violated, you can find oil pressure problems. Worn bearings may not maintain proper oil pressure.

So, you will notice a drop in force on the oil pressure gauge. Engine oil’s non-magnetic metal particles indicate that you have worn engine bearings. But if they are magnetic, it could be due to backing material in bearings or the engine’s other parts.

Metal In Oil Filter After Rebuild:

If you can’t find metal on filters or ignore it, it can make your engine a big problem. But when you see any metal on an oil filter, you must attempt a logical strategy.

Don’t panic if your engine is for temporary use. On new or rebuilt motors, a few metals from manufacturing on oil filters aren’t very unusual. On dry sump engines, remember to clean the oil tank. You need to clean or replace oil coolers and oil lines properly.

In some rare cases, the filter itself may be made of metal. Closely check the end of the inner relief valve ball. Additionally, if the ball is distorted, this could be the culprit. Replace screen assembly.

Metal Shaving on Oil Dipstick:

Small shavings in your oil are regular if you have kept your oil the same since you bought the car. If you’ve changed the oil since purchasing the vehicle, it’s not good. Mainly, if you see a swirl in engine oil, it causes metal shaving. You should spend some money to change your oil and oil filter.

Engines are large assemblies of metals and parts made within tolerances, so they produce some shavings during engine breaks. As the tube is pulled out, it becomes just magnetized and scrapes the tube side, causing the metal to stop.

Remember to flush your oil coolers once your problem is solved. The only way to fix this is to replace the cam and rockers. Also, don’t forget to do this work at the same time.

Solution Of Glitter In Oil After Rebuild:

To fix the problem of glitter in oil after rebuild, you can try to drive it a few hundred miles. Then, pour a quart of oil into a clean container and test again. If it’s clear, the glitter may be from normal wear and tear. But if you can see there is still glitter, you have a bigger problem. Here are more of the techniques:

Compression or Leak-down Test

Adequately, with compression or leak-down, you can know about the health of the car’s engine. To make power, the car’s motor takes compression. This checking process lets you know if the cylinder lost compression and for what reason.

Oil Analysis

Generally, when you change your oil and send the oil sample every time, the oil analysis company can understand the problem. For instance, if they discover extra copper particles in the oil, it could be due to lousy rod bearings.

FAQ (Frequently Asked Questions):

Q. How much metal is in the first oil change?

It’s hard to tell without looking, but cutting the oil filter and inspecting the components is good. To do this, you need a special oil filter cutter. When checking the material, see pepper flakes or large particles. This will indicate a problem.

Small pieces of the size called “dust” in minimal volumes are usually seen in wear. Change the oil and filter, and run the engine for 250 to 500 miles. Then, pull the filter and recheck the component. If it’s clear, you are safe.

Q. Why is my oil silver?

Aluminum steel is one of two types of clutch plates: fiber and steel. If you run aluminum “steels,” the oil will always be silver. A magnetic drain plug cannot pull aluminum from the oil. Water or coolant will make it white, not silver.

Q. What does it mean when you change your oil, and it looks like there’s glitter in the old oil?

When you change your oil and see glitter, it means your oil contains metal flakes. But of course, it depends on how big the metallic flakes are and when you changed your oil last. Engine wear always occurs over time and is caused by wear of metal components. If it is clear, the glitter may be from normal wear.

Final Word:

On the other hand, since oil is the lifeblood of any engine, constantly inspecting your oil is very important. It’s because if you ignore checking your oil frequently, it can ruin your engine. So when you see glitter in oil after rebuild, please don’t ignore it. You should find out the reason, and you need to fix the problem as soon as possible. We hope after reading this article, you can fix the problem quickly.
