It is unsafe to jack up the car by placing the jack under the engine
Jacking up a car to change the oil or do other work is a common practice, but it is important to take safety precautions to avoid damage to the car or injury to yourself. While it may be possible to jack up the engine on the oil pan, it is generally not recommended as it can be unsafe and may damage the oil pan. Here are several reasons why it is unsafe to jack up a car by placing the jack under the engine:
Firstly, the oil pan may not be able to withstand the weight of the engine. Engine pans are typically thin and may dent or break under the load. This can result in oil leaks and costly repairs. To avoid this, it is advisable to use a jack stand or place a block of wood between the jack and the oil pan to distribute the weight more evenly and reduce the risk of damage.
Secondly, jacking up the engine by the oil pan can affect the stability of the car. When a car is jacked up from the middle, the weight distribution changes, and the car may become unstable, especially if it is lifted too high. This instability can lead to the car slipping off the jack or falling, which can be extremely dangerous and cause serious injuries.
Additionally, placing the jack under the engine may not provide enough clearance to work under the car. In some cases, you may need to access areas that are blocked by the engine when it is jacked up in this manner. This can make it difficult to perform the necessary maintenance or repairs.
Furthermore, jacking up the engine by the oil pan can put unnecessary strain on the engine and its components. The force exerted by the jack can transfer to the engine block, transmission, and other parts, potentially causing damage or misalignment. It is important to use the designated jacking points on the car's body to ensure a safe lift.
Lastly, it is important to follow the manufacturer's recommendations for jacking up a car. Most vehicles have specific jacking points, usually reinforced metal ribs, designed to safely lift the vehicle. Deviating from these instructions can compromise safety and increase the risk of accidents or damage to the vehicle. Always refer to the user manual or maintenance guides to identify the correct jacking points and procedures for your specific car model.

Placing a block of wood between the jack and oil pan can prevent damage
Jacking up your car using the oil pan is not recommended. However, if you're simply lifting the engine to relieve the weight off the engine mounts, it can be done safely. One of the most important precautions is to place a block of wood, a hockey puck, or a similar object between the jack and the oil pan to distribute the weight and prevent damage to the pan.
The block of wood should be long and thick enough to span the entire width of the pan, ensuring that the weight is borne by the vertical sides of the pan and not just the middle. This will prevent the jack from denting or crushing the oil pan. The wood will compress a bit when lowering the car down onto it, and the jack stand will dig into the wood, which is normal. It is also important to note that the grain of the wood should be aligned perpendicularly to any small pressure points to prevent the wood from splitting.
Before attempting to jack up the engine, it is recommended to loosen the necessary bolts, such as the motor mount bolts and transmission bolts, to allow for easier lifting of the engine. It is also a good idea to disconnect the air intake hose and loosen the front transmission-to-mount bolts to minimize the weight and stress on the pan. Additionally, make sure there are no tight cables or components that could snap under tension when you lift the engine.
When jacking up a car, always use jack stands for added safety. It is also recommended to work with a helper to ensure a safe lifting process.

Jacking up the engine slowly and gently is important
Jacking up the engine slowly and gently is of utmost importance to ensure safety and prevent damage to the vehicle. A sudden jerk or excessive force can damage the oil pan, denting or crushing it, and may even damage the oil return or pickup. The oil pan is generally not designed to bear the weight of the engine or the entire vehicle, so it is crucial to distribute the weight and avoid concentrating pressure on a small area.
To achieve this, it is recommended to use a block of wood, plywood, a 2x4, or a similarly sized object between the jack and the oil pan. This will spread the load and protect the oil pan by ensuring that the weight is borne by the vertical sides of the pan rather than the middle. Additionally, using carpet scraps, cardboard, or rags can further spread the weight and protect the pan.
Before attempting to jack up the engine, it is advisable to loosen the necessary bolts, such as the motor mount bolts and, in some cases, the transmission bolts. This will make it easier to lift the engine and reduce the risk of damage to other components. It is also important to remove any tight cables or components that could snap under tension when lifting the engine.
When jacking up the engine, it is crucial to do it slowly and gently, lifting the engine only slightly. The goal is to raise the engine just enough to take the weight off the motor mounts and allow for their removal, rather than lifting the entire vehicle. A gradual lift will help prevent any sudden drops or instability, ensuring a secure and controlled environment for maintenance or repair work.

Jackstands should be placed underneath for safety
Jack stands are an essential tool to ensure safety when working underneath a car, truck, or trailer. They are also necessary when loading and unloading trucks to ensure the safety of workers. When jacking up an engine on an oil pan, it is imperative to place jack stands underneath for safety. Here are some crucial considerations and guidelines for their proper use:
Placement on a Flat Surface
Always use jack stands on a flat surface. Even a slight slope can cause the vehicle to roll or shift, potentially leading to serious consequences. Ensure the ground is level and stable before positioning the jack stands.
Proper Weight Rating
It is critical to use jack stands that are properly rated for the weight of the vehicle. Determine the weight of your vehicle from the owner's manual or online resources. Divide that weight by two to get the minimum load rating required for a pair of jack stands to support either the front or rear of the vehicle. However, for added safety, it is recommended to use a higher load rating than the minimum. Remember that weight is just one factor, and other considerations, such as the distribution of weight, also come into play.
Use with a Floor Jack
When using jack stands, it is common to employ them in conjunction with a floor jack. Ensure that the floor jack is also properly rated for the weight of the vehicle and sourced from a reputable company. When jacking up the vehicle, cover as much of the jack point's center as possible while leaving enough room for the jack stand.
Safety Measures
To enhance safety, opt for ratcheting jack stands with redundant safety features, such as manually insertable safety pins that provide additional load-bearing capacity. Additionally, follow general safety protocols, such as setting brakes, using wheel blocks, and immobilizing the vehicle to prevent any unintended movement.
Placement with Engine Jacking
When jacking up an engine on an oil pan, it is crucial to place the jack stands directly underneath the engine and oil pan assembly. This provides support and stability, preventing the engine from shifting or falling during the jacking process. Ensure the jack stands are securely locked in place and can withstand the weight of the engine without slippage.
In summary, when jacking up an engine on an oil pan, the placement of jack stands underneath is of utmost importance for safety. By following the guidelines outlined above, you can help ensure a secure and stable environment for working underneath the vehicle. Remember to prioritize safety and always use the appropriate equipment for your specific vehicle.

Some suggest jacking the car from the front crossmember instead
Jacking up a car from the front crossmember is a safe method, according to several forum users. One person recommends using a small jack on one of the jack spots behind the front tyres. Once the front is raised, a flat piece of wood can be slid under the crossmember to protect the car's finish. The shop manual also advises using a jack on the crossmember to raise the front. However, it is important to exercise caution and refer to the car's manual to identify the correct jack points.
Some people express concern about jacking up the car from the front crossmember. One forum user cautions that the front crossmember is primarily a battery support panel and recommends lifting only in the designated colour-coded areas or in the middle of the rear crossmember. They suggest using low-profile wheel ramps or a trolley jack to lift the car safely.
It is worth noting that modern unibody vehicles often lack traditional jacking points, making the crossmember a viable option for lifting the car. However, it is recommended to use jack stands under the control arms as an additional safety measure.
When jacking up a car, it is always important to prioritise safety. One person suggests placing a jack stand underneath the car for added security. Additionally, when working underneath a raised car, it is crucial to ensure that the vehicle is securely supported to prevent accidents.
While jacking up the front of the car from the crossmember is possible, it is important to refer to the specific make and model's manual for the recommended jacking points. Using wheel cribs, backup jack stands, or a Quick Jack lifting system can also be considered for a safer and more stable lifting process.
