How to Remove Dipstick Tube from Engine Block (6 Steps)

Have you ever struggled to pull out a stuck dipstick tube from your engine block? I did too. It felt like it would break, twist, or snap. But after many tries and some learning, I finally found a simple way to remove it safely without damage. In this article, I will share the full process of how to remove dipstick tube from engine block in a clear, easy, and step-by-step way, even if you have never done it before. You will be able to do it with simple tools, patience, and the right method.

Find the Dipstick Tube Location in the Engine Bay

Before you can remove the dipstick tube, you need to find where it is in your engine. The dipstick tube is a long metal or plastic pipe that holds the dipstick, which is used to check engine oil. It usually sticks out from the engine block, and it’s often bright yellow, orange, or has a round handle at the top. This helps you pull the dipstick out easily to check your oil level.

Now, open the hood of your car. Look around the engine bay. The dipstick tube is normally located on the side of the engine. If your engine is a V-type (like a V6 or V8), it may be on either the left or right side. If your engine is a straight type (like an inline-4), it’s usually in the front or back of the engine. Look for the tube connected into the lower part of the engine block.

Some tubes are straight, others are bent. Some have brackets that hold them in place. It may also go behind wires, hoses, or parts like the intake manifold. Don’t rush. Take your time to look around the engine.

If you’re not sure it’s the dipstick tube, follow the dipstick itself. When you pull it out, you’ll see the long metal stick is sitting inside the tube. That’s the one you need to remove.

Once you find it, check how it’s connected to the engine. Some dipstick tubes are held with a bolt to the engine or a bracket. Some are just pushed into a hole and sealed with an O-ring. It’s important to know this before pulling.

  • Open the hood and let the engine cool.
  • Look for the dipstick handle near the engine.
  • Follow the dipstick to locate the tube.
  • Notice how it connects to the engine block.
  • Check if there’s a bolt or just an O-ring seal.

Remove Any Brackets or Bolts Holding the Tube

Once you find the tube and how it’s mounted, the next thing to do is remove anything holding it. This is very important because if you pull too hard while it’s still bolted down, you might bend or break the tube.

First, check near the top or middle of the tube. Most dipstick tubes have a metal or plastic bracket that is bolted to the engine or intake. Use a flashlight to see better. This bracket keeps the tube from moving while driving.

Use the correct socket or wrench, usually 10mm or 13mm, to loosen the bolt. Turn it slowly. If it’s rusty, spray a little bit of penetrating oil like WD-40 and wait a few minutes. Be gentle when you loosen it. Once it’s free, keep the bolt in a safe place. You will need it later when you install the tube back.

Some tubes have more than one bracket. You must remove all of them. Some might be hard to reach. Take your time. Use a long extension bar if needed.

After removing the brackets, gently try to wiggle the tube. If it moves slightly, that’s good. That means it’s getting loose. But don’t pull it out yet. Make sure all bolts or clips are off.

  • Look for bolts or brackets on the dipstick tube.
  • Use the right size wrench to loosen and remove them.
  • Spray oil if bolts are rusty.
  • Keep bolts in a safe place.
  • Gently test if the tube is loose.

Loosen the Tube by Twisting Gently

Now that the brackets or bolts are off, you need to gently loosen the dipstick tube from the engine block. The dipstick tube may still be stuck inside due to dirt, heat, or the rubber O-ring seal. You should not pull it out straight without first loosening it. That can damage the tube or the engine hole.

To start, grab the tube with your hand. Hold it close to where it enters the engine. Try twisting it left and right gently. Do not twist hard. Just small movements to help break the seal inside the engine. If the tube doesn’t move, you can use a rubber strap wrench or wrap a cloth around it for a better grip.

Sometimes, the tube won’t move at all. If that happens, don’t force it. Instead, try tapping it lightly with a rubber mallet near the base. Do not hit it hard or use a metal hammer. That can crush or bend the tube.

If it still doesn’t move, spray a little penetrating oil around the base of the tube where it enters the engine. Wait 10–15 minutes and try again. Keep twisting slowly and gently. Patience is the key.

Once the tube starts moving a little, it will soon come out easily. Do not yank it.

  • Hold the tube near the engine block.
  • Twist gently left and right.
  • Use a strap wrench or cloth for grip.
  • Tap lightly with a rubber mallet if needed.
  • Spray oil if stuck and wait before trying again.

Pull the Tube Out Without Breaking It

Once the dipstick tube is loose and moving, it’s time to carefully pull it out from the engine block. This is a very important part. If you pull too fast or at the wrong angle, you can break the tube or damage the hole it sits in.

Hold the tube firmly with both hands. One hand should be close to the engine, the other further up. Now, slowly twist and pull at the same time. Do not jerk it. Pull in a straight line as much as possible. If the tube is bent, follow its natural curve while pulling.

Some tubes have a rubber O-ring at the end. This ring can make it tight when coming out. If you feel strong resistance, stop and twist more. A little movement left and right will help slide the O-ring out.

If your engine has rust or old oil buildup, the tube may come out with some force. Be ready. Don’t fall backward or let it fly out of your hand.

Check the tube once it’s out. Make sure it’s not bent, cracked, or broken. Also, check if the O-ring is still there. Sometimes, the O-ring stays inside the engine. If it does, remove it with a pick tool or long nose pliers.

  • Hold tube with both hands.
  • Twist and pull slowly in a straight line.
  • Do not force or jerk the tube.
  • Be careful of O-ring resistance.
  • Check the tube and O-ring after removal.

Clean the Tube and Engine Hole Before Reinstalling

Now that the dipstick tube is out, you should clean both the tube and the engine hole. This helps prevent future leaks and makes reinstalling much easier. Dirt, rust, or old oil can stop the tube from sealing properly when you put it back.

Start with the dipstick tube itself. Wipe it clean with a shop rag or paper towel. Check for rust or damage. If it’s dirty or greasy, spray some degreaser or brake cleaner on it. Then wipe again. If there’s rust, use fine sandpaper to clean the metal.

Now, look at the hole in the engine block where the tube came out. Use a flashlight to check for any dirt or pieces of the old O-ring. Carefully clean the hole using a cloth or soft brush. Do not push dirt inside the engine.

You can also spray a small amount of cleaner into the hole, but never too much. Avoid using anything sharp or metal to dig inside the hole. You don’t want to scratch it.

Once everything is clean, let it dry fully. If the O-ring on the tube is old or damaged, replace it with a new one. This small rubber ring helps seal the oil and keep dirt out.

  • Wipe the dipstick tube clean.
  • Check for rust or damage.
  • Clean the engine hole gently.
  • Use soft tools and cleaners only.
  • Replace the O-ring if needed.

Reinstall the Dipstick Tube Securely

After cleaning, it’s time to put the dipstick tube back into the engine block. Make sure everything is dry and clean. This step is just as important as removing it. If not done right, it can cause oil leaks or a loose fit.

Start by applying a little bit of oil on the O-ring at the bottom of the tube. This helps it slide into the hole easier. Now, align the tube with the hole. Slowly push it in with a little twisting motion. Don’t hammer it in. Just use steady hand pressure.

Push until the tube is fully seated in the hole. You will feel it stop once it is in all the way. Now, align the bracket with its bolt hole on the engine or intake.

Reinstall the bolt you removed earlier. Use the correct socket and tighten it just enough. Don’t overtighten or you could crack the bracket or tube.

Check that the tube is tight and doesn’t move. Put the dipstick back inside to make sure it fits properly.

  • Lightly oil the O-ring.
  • Push the tube in with gentle twisting.
  • Make sure it sits all the way in.
  • Reattach and tighten the bolt or bracket.
  • Check for tight fit and reinstall dipstick.

Frequently Asked Questions (FAQs)

Is it hard to remove a dipstick tube?

Removing a dipstick tube is not very hard, but it can be tricky if you have never done it before. If the tube is old or stuck with rust, it may not come out easily. But with the right tools and gentle twisting, you can remove it safely. It’s all about being careful and not forcing anything. Anyone can do it with patience.

Can I pull the dipstick tube out without removing bolts?

No, you should not pull the dipstick tube without first checking for bolts or brackets. Most tubes are held in place with a bolt or clip that keeps them steady during engine movement. If you pull it while it’s still bolted, you can damage the tube or engine. Always remove all brackets first to keep everything safe and smooth.

Do I need to replace the dipstick tube O-ring?

Yes, if the O-ring is cracked, worn out, or missing, you should replace it. The O-ring is a small rubber ring that seals the dipstick tube in the engine block. If it’s damaged, oil can leak, or dirt can get inside your engine. It’s cheap and easy to replace, and it’s always better to do it while the tube is out.

Is it okay to tap the dipstick tube with a hammer?

You should never use a regular metal hammer on a dipstick tube. The tube is thin and can bend or break easily. If it’s stuck, you can tap it gently with a rubber mallet, but always be very gentle. The best way is to twist and pull slowly with your hands. Hitting the tube can cause more problems.

Can I drive without a dipstick tube?

No, you should not drive your car without the dipstick tube. It helps keep the oil sealed inside and prevents dirt from getting into the engine. Without the tube, oil can splash out and cause damage or mess. Always make sure the tube is in place before starting the engine or going anywhere.

Do I need special tools to remove a dipstick tube?

Most of the time, you don’t need special tools. A basic wrench or socket set is enough to remove bolts. You might also need a rubber mallet, cloth, or strap wrench if the tube is stuck. But you don’t need any expensive tools. Most of these things are found in a regular toolbox.

Is it normal for the dipstick tube to be hard to remove?

Yes, sometimes it’s normal, especially if the tube has been in place for a long time. Heat, dirt, and old oil can make the tube stick. But if you follow the proper steps, like twisting gently and using oil, it will come out. Just be patient and don’t force it out quickly.

Can I reuse the same dipstick tube after removing it?

Yes, you can reuse the same dipstick tube if it’s not damaged. Check it carefully for cracks, bends, or a broken O-ring. If it’s in good shape and clean, it can go back into the engine. Just make sure it fits tight and seals well. If it feels loose or damaged, you should replace it.
