Causes Of An Over Tightened Oil Plug

Causes Of An Over Tightened Oil Plug

Definition 

An oil plug is a stopper that prevents the liquid in the oil pan from leaking or draining.

The grease lubricating various components of the car is contained in the oil pan. The draining process of an oil pan is important as the oil in your vehicle needs to be changed periodically.

When the plug is overly tightened, it poses a certain risk to the vehicle, which is not as serious as the risk of driving without an oil cap, but still requires attention.

Causes 

Sludge

After each time of changing the oil, there is a certain amount of the lubricating liquid that exceeds staying around the plug.

The high temperature from the engine of the vehicle then makes that excess oxidize.

During this process, the engine grease’s molecules break down and stick to the dirt mixture released from the combustion. Particularly, the mixture includes fuel, water, carbon, and metallic particles.

This combination builds up a sticky sludge, which explains why you can’t loosen oil drain plug.  

Over-Tightening

The second reason is more simple; the plug is extremely tightened after opening.

This cause is undoubtedly common as the amateur drivers or newbies in the mechanic shop do not have enough mechanical skills and knowledge while doing regular maintenance.

Over-tightening leads to a bad effect on the crew pitch. As a result, you are required to swap the oil pan in whole.

Check the surrounding areas, do necessary maintenance and apply a new plug at its relevant position.

Rust

If the stopper is not regularly removed or you leave it untouched for a long period, there will be rust building up.

This phenomenon mostly happens to vehicles without proper maintenance or getting old after long use.

Effects

When the oil stopper is overtightened, it will damage itself first. Then, it even ruins the rubber gasket as well as slices your threads.

Although the plug is used to seal the greasy liquid used for your engine lubrication and function, your oil change gets more complicated when it is tightened immensely.

How To Reinstall And Avoid An Over Tightened Oil Plug

Instructions To Reinstall

After knowing how to remove stuck oil drain plug, are you confident that you can reinstall the stopper properly? Follow the guidance below to avoid making mistakes.

Step 1. Choosing the best tools. If you want to DIY reinstall, you should purchase bolt extractor equipment to make the process less challenging.

These tools will remove the sludge, rust, rounded, and effortlessly tighten the stoppers in a couple of minutes.

Go to a mechanic market; bolt extractors are available in a wide range of sizes.

Choose the most fitted ones based on the requirements of your automotive bolt. For long service, investing in a bolt grip extractor made from high carbon steel is better.

Step 2. Locate the position. Numerous amateurs find it confusing to determine the location of the plug. Generally, it is a big nut lying in the area where all the grease rests.

Particularly, it is at the oil pan’s lowest point underneath the engine. As a result, the draining amount is at its maximum during oil exchange.

You can either crawl the car’s bottom or lift it using a hydraulic jack to find the bolt.

Step 3. Reinstall. Use a piece of wet cloth to clean the teeth of the lubrication pan and replace it with a new gasket.

Use a socket wrench to tighten the gasket for repositioning. Do not make it hard or over-tighten.

Tips For Success

  • Use a high-quality engine lubricate to reduce the possibility of sludge on the bolt.
  • Ensure that when you insert the stopper into the drain nut together with a new washer made from metal, the component goes straight instead of an angle.

Tighten it by hand with the female threads on the aluminum grease pan. If the plug goes in an angle, the threads on it will damage the threads on the hole.

  • Go for a torque wrench, socket, or box spanner to tighten. Set the tool to the suggested torque that will be found in the brand’s manual.
  • Do not offer too much power or pressure during the tightening process even when you have known how to loosen oil bolt properly. Open-ended spanners are also not a good choice for loosening or tightening the grease stopper.
  • Remember to follow the recommended intervals for oil changing. Or else irregular changing will lead to common issues like sludge buildup or dirt sticking.

How Can I Remove A Stripped Oil Drain Plug?

Although having a stripped oil seal is annoying, don’t worry, as this process just requires a simple technique. You can even apply various methods to deal with this issue.

Firstly, prepare a screwdriver with a flathead and a hammer. Take into practice the Sheer Force theory by tapping on the head of the plug with the screwdriver.

Put on extra pressure with the hammer. This is the popular method used by professionals.

Meanwhile, heating is also another helpful solution based on thermal expansion. The high temperature will expand the metal properties, including the lubricate bolt.

If you have enough experience and skills, use the heat guns to reduce the effect on the surrounding components and return the plug’s original shape quickly when it cools down.
