Drain the engine oil

To clean your oil pan pickup tube without removing the oil pan, you will first need to drain the engine oil. Place a drain pan underneath the engine and remove the drain plug, allowing the oil to flow out. Once the oil has drained, you can proceed to the next steps of cleaning the oil pan pickup tube.

It is important to note that simply draining the engine oil may not be sufficient to address a clogged oil pan pickup tube. The clog could be due to various factors such as sludge, debris, or carbon buildup. Therefore, additional steps may be necessary to effectively clean the tube and restore proper oil flow.

One approach to cleaning the oil pan pickup tube without removing the pan is to use a chemical solvent or cleaning agent. After draining the engine oil, replace the drain plug and pour a gallon of a suitable solvent, such as Berryman B-12 Chemtool, kerosene, or a similar product, into the engine oil fill. Do not crank the engine after adding the solvent. Allow the solvent to sit in the oil pan for at least two days, as this will help to dissolve any sludge or buildup in the pickup tube.

After the solvent has had sufficient time to work, drain it from the oil pan and inspect the discharge. If it appears dark and sludgy, the cleaning process may need to be repeated. Feel between your fingers for carbon grit, as this can also contribute to clogging the pickup tube screen. Repeat the solvent treatment until the discharge is free of sludge and grit.

Overall, draining the engine oil is the first step in cleaning the oil pan pickup tube without removing the pan. It provides access to the tube and allows for the application of cleaning agents. However, further steps, such as the use of solvents and inspection, are crucial to ensuring the effectiveness of the cleaning process.

Pour in a gallon of Berryman B-12 Chemtool

Pouring a gallon of Berryman B-12 Chemtool into your oil pan is an effective way to clean it without removing the pan. This method can help dissolve any gum, varnish, or fuel residue that may have built up in your oil pan and is a good option if removing the pan is not feasible.

To use this method, first drain the oil from your engine. Then, pour a gallon of Berryman B-12 Chemtool into the oil fill. You can then choose to either let the solution sit overnight or crank the engine in short bursts before draining the solution and refilling with fresh oil.

It is important to note that some people recommend against using chemicals to clean the oil pan, as it may affect seal leakage. Additionally, if you are unsure of the cause of the clog, it may be best to simply replace the oil pan and gasket. However, if you are unable to remove the pan, using Berryman B-12 Chemtool can be an effective alternative.

Berryman B-12 Chemtool is a fuel system cleaner that is designed to quickly disperse moisture and dissolve gum, varnish, and fuel residues from fuel systems. It is available in both consumer and commercial sizes and is safe for catalytic converters and oxygen sensors. It is also important to note that this product is extremely flammable and should be handled with care.

Let it sit for two days

To clean the oil pan pickup tube without removing the pan, you can try the following method: drain the oil, pour a gallon of kerosene in the oil fill, and let it sit for two days. This process will help to dissolve any built-up sludge or debris in the tube. After two days, drain the kerosene, flush the tube with cheap oil, and then refill it with new oil.

Letting the kerosene sit in the oil pan for two days is crucial to the effectiveness of this cleaning method. This soaking time allows the kerosene to thoroughly penetrate and break down any sludge, gunk, or debris that has accumulated in the oil pan pickup tube. By giving the kerosene time to work, you increase the chances of successfully removing the built-up contaminants and restoring the tube's functionality.

The two-day waiting period also provides an opportunity to inspect other components of your vehicle. With the oil drained and the kerosene sitting in the pan, you can take a closer look at the engine, oil filter, and other nearby parts. This downtime can be productively used to assess the overall condition of your vehicle and identify any potential issues that may require attention.

Additionally, during these two days, you can prepare the necessary tools and materials for the next steps of the cleaning process. It is important to have everything ready before proceeding. This includes having a suitable container to catch the drained kerosene, fresh oil for flushing, and a new oil filter if needed. By letting the kerosene sit for two days, you create a window to gather all the required supplies and plan the subsequent steps efficiently.

In conclusion, letting the kerosene sit in the oil pan pickup tube for two days is a critical step in this cleaning method. It ensures that the kerosene has sufficient time to dissolve sludge and contaminants, reducing the risk of damaging the engine. This waiting period also allows for a thorough inspection of the engine and preparation for the next steps, making the overall cleaning process more effective and organised.

Drain and repeat if necessary

Draining the engine oil is the first step in cleaning the oil pan pickup tube. This is done by removing the oil filter and drain plug, and collecting the oil in a drain pan. Once the oil is drained, the process of cleaning can begin.

The next step is to pour a solvent or cleaning fluid into the engine oil fill. Different sources recommend different products for this step, including Berryman B-12 Chemtool, kerosene, carburetor cleaner, or a generic engine flush product. The amount of product to be used can vary, with some sources suggesting one gallon, and others suggesting only a few quarts.

After the solvent is added, it is important to let it sit for a period of time. Most sources recommend leaving it for at least two days, or possibly longer if desired. This allows the solvent to work on breaking down any sludge or buildup in the oil pan and pickup tube.

Once the solvent has been given enough time to work, it is then drained from the oil pan. At this point, it is important to inspect the solvent as it is drained to determine if the cleaning process has been successful. If the solvent appears as a dark sludge, or if carbon grit can be felt when rubbing the discharge between two fingers, then the process will need to be repeated. In this case, the solvent is drained and replaced, and the engine is allowed to sit for another two days before draining and inspecting again. This process can be repeated as many times as necessary until the solvent appears clean and free of sludge or grit.

It is important to note that some of the products used in this process are highly flammable, so extreme caution should be exercised throughout.

Crank the engine

Cranking the engine is one of the steps in cleaning the oil pan pickup tube without removing the pan. This method involves draining the oil, pouring a gallon of kerosene in the oil fill, disabling the ignition, and cranking the engine in 2-3 second bursts. Let it sit overnight, then drain, flush, and refill.

Cranking the engine is a straightforward process, but it does require some strength and the right tools. Here are the steps to follow:

• Remove the spark plugs: Take out all the spark plugs before attempting to turn the engine. This will make it significantly easier to turn the crankshaft and reduce the amount of strength required.
• Put the car in neutral: Ensure that the car is in neutral gear before attempting to turn the crankshaft.
• Use a socket wrench: Attach a socket wrench to the main pulley, harmonic balancer, or crankshaft pulley. This will allow you to turn the engine with greater ease.
• Direction of rotation: The correct direction to turn the engine is clockwise when facing the front of the engine. While it won't cause any damage, avoid turning the engine counterclockwise, as it may affect the camshaft lobes.
• Apply moderate force: Depending on the condition of the engine, you may need to apply some force to turn the crankshaft. However, be careful not to use excessive force, as it may lead to damage.
• Monitor cylinder position: If you need to perform a cylinder leak-down test, ensure that each cylinder is in Top Dead Center (TDC) during the test. You can achieve this by following specific procedures, such as feeling for air pressure with your thumb or using a wooden dowel.

Remember, cranking the engine is just one step in the process of cleaning the oil pan pickup tube. It is important to follow all the steps correctly and take the necessary precautions to avoid any potential damage to your vehicle.
