What to Do When an Oil Dipstick Broke off in Tube

An oil dipstick is a tool used to measure the amount of oil in the engine of a vehicle. It can be made from metal, plastic or rubber and is inserted into an oil tube that runs from the engine and connects to the oil pan beneath it. Unfortunately, sometimes these dipsticks can break off in their tubes, leading to further damage that needs repair. In this article, we’ll discuss what to do if your oil dipstick breaks off in its tube and how to fix it properly.

Causes of Oil Dipstick Broke off in Tube

There are several potential causes for an oil dipstick broke off in tube. Here are some common reasons:

What to Do When an Oil Dipstick Broke off in Tube Age and wear: Over time, the dipstick can become weakened or brittle due to continuous exposure to high temperatures, oil, and engine vibrations. This can eventually lead to the dipstick breaking off inside the tube.

Mishandling or improper use: Rough handling or excessive force when inserting or removing the dipstick can cause it to snap off. It’s important to handle the dipstick with care and follow proper procedures when checking the oil level.

Engine overheating: If the engine overheats, the excessive heat can affect the dipstick’s integrity, making it more prone to breaking. Overheating can be caused by factors such as a malfunctioning cooling system, low coolant levels, or a faulty thermostat.

Oil sludge buildup: Inadequate maintenance and neglecting regular oil changes can result in the accumulation of oil sludge, which is a thick, gel-like substance. This sludge can clog the dipstick tube, causing resistance or blockage and potentially leading to a broken dipstick.

Corrosion or rust: Exposure to moisture and contaminants, especially in vehicles driven in harsh environments or those exposed to saltwater, can cause corrosion or rust on the dipstick. This corrosion weakens the metal, increasing the risk of breakage.

Defective or low-quality dipstick: In some cases, a dipstick may have manufacturing defects or be made from substandard materials. These factors can contribute to the dipstick’s vulnerability and increase the likelihood of it breaking.

It’s important to address a broken dipstick promptly, as leaving a broken piece inside the dipstick tube can cause further complications, such as oil leaks or difficulty checking the oil level accurately. If you encounter a broken dipstick, it is recommended to consult a qualified mechanic for proper diagnosis and repair.

Steps to Take if an Oil Dipstick Breaks off in the Tube

If you find yourself in a situation where the oil dipstick breaks off inside the tube, there are a few steps you can take to address the issue. Firstly, try not to panic or force anything, as that could potentially cause further damage. Carefully inspect the broken dipstick to determine how much of it remains inside the tube. If large fragments are sticking out, you may be able to gently pull them out using pliers or needle-nose grips. However, it’s crucial to be cautious and avoid pushing the broken piece further into the tube. If there are smaller particles or debris left inside, you can try using a small flathead screwdriver to help remove them. Applying a penetrating oil and allowing it to soak for a short period may also aid in loosening any stuck fragments. If you encounter difficulties or are uncertain about how to proceed, it’s recommended to seek assistance from a professional mechanic who can safely remove the broken dipstick and assess if any further actions or repairs are necessary.

How to Replace an Oil Dipstick After It’s Broken Off in the Tube

Once the broken dipstick has been removed, it’s important to replace it with a new one. The exact process of replacing a dipstick will vary depending on the make and model of your vehicle but typically involves draining some oil from the engine and then inserting the new dipstick into its tube. Make sure you purchase a dipstick that is compatible with your vehicle and use caution when inserting it into its sleeve. Once installed, check for any signs of leaks or damage and ensure that there is no debris left inside.


In conclusion, it’s important to take appropriate steps if your oil dipstick breaks off in its tube. First, carefully assess the situation and use caution when attempting to remove any remaining fragments of the broken dipstick. If you are uncertain or require technical assistance, consult a qualified mechanic for further advice. Finally, it is necessary to install a replacement dipstick that is compatible with your vehicle. Following these steps will help ensure that the repair process is handled properly and safely.
