Skid Plates: Oil Pan's Guardian, Explained

Skid plates are a great way to protect your oil pan from damage when off-roading. While it may be rare to puncture your oil pan, it can happen, and even minor damage can lead to rust over time. Skid plates can also protect your oil pan from rocks that might chip away paint. There are many options for skid plates, including ones that cover the entire underside of the oil pan and ones that only cover part of it. Some people choose to make their own skid plates, while others purchase them from companies like Rubicon Express, Skid Row, or Metalcloak. When choosing a skid plate, it's important to consider the pros and cons of different styles and to ensure that it is installed correctly to provide adequate protection.

Skid plates can protect against rust by preventing paint chips

Skid plates are a great way to protect your vehicle's oil pan from damage when off-roading. They can also help prevent rust by shielding the oil pan from rocks and other debris that could chip the paint and expose the metal to moisture and the elements.

While it may be a rare occurrence to puncture your oil pan, it is certainly possible, and the consequences could be dire. A skid plate provides a layer of protection, potentially saving you from a costly repair and the loss of engine oil.

The installation of a skid plate can be a relatively simple modification, and it can be fitted to almost any 4x4 with an exposed oil pan. The skid plate is attached directly to the oil pan, typically using bolts or welding. However, welding thin steel can be challenging, and there is a risk of burning a hole in it. As an alternative, some people have suggested using silicone to glue the skid plate in place. This method provides strong adhesion and can also allow for some flexibility to absorb the shock of impacts.

In addition to protecting against paint chips, skid plates can also help prevent rust by keeping the undercarriage of your vehicle drier. While there are concerns that skid plates may trap sand and mud, promoting rust, the benefits of protection from paint chips, moisture, and other debris far outweigh this risk for those who off-road frequently or even moderately.

To further enhance the protection of your vehicle, you can also consider painting your skid plate. While regular spray paint or automotive paint can be used, they may not hold up well to impacts with rocks. More durable options include bed liner paint or liquid Rustoleum, which can provide a thicker coating that is better able to withstand chips and scratches.

They can be made from steel

Skid plates are used to protect the underside of a vehicle from damage when it comes into contact with the ground. They can be used on off-road vehicles, motorcycles, and lowered vehicles. They can be made from steel, aluminium, plastic, or fibreglass. Steel skid plates offer several advantages over other materials.

Firstly, steel is a highly durable material. It is stronger and less malleable than aluminium, meaning it can withstand more repeated impacts. Steel skid plates can handle more abuse and are less likely to crack or break than aluminium ones. This makes steel a good choice for those who engage in aggressive or hard wheeling. Additionally, steel creates less friction with rocks than aluminium, allowing the vehicle to slide over obstacles more easily.

Steel skid plates also offer increased resistance against any impact or debris found on the road. They can protect the engine, gearbox, and oil pan from damage, as well as prevent rust and corrosion. Steel skid plates can also increase the lifespan of the vehicle compared to skid plates made from other materials, such as plastic or fibreglass.

Another advantage of steel skid plates is their cost-effectiveness. They tend to be less expensive than aluminium skid plates, making them a more attractive option for those on a budget. Steel skid plates are also easier to work with than aluminium, as aluminium is tougher to form and weld due to its malleability.

However, steel skid plates do have some drawbacks. They are typically heavier than aluminium skid plates, which can impact the vehicle's mileage and overall performance. The added weight of steel skid plates can also affect the centre of gravity of the vehicle. Additionally, steel is more susceptible to corrosion and rust, especially when exposed to road salt.

Ultimately, the choice between steel and aluminium skid plates depends on the specific needs and preferences of the user. Steel skid plates offer increased protection and durability but may impact the vehicle's weight and performance. They are a good choice for those who prioritise protection and engage in aggressive off-roading, while aluminium skid plates may be preferred by casual overlanders who want to reduce the weight of their vehicle.

They can be attached using silicone

Skid plates are a great way to protect your oil pan from damage when off-roading. While it may be a rare event to puncture your oil pan, it can happen, and even minor damage like paint chips can lead to rust over time.

One inventive off-roader came up with a way to attach a skid plate to their oil pan using silicone. They started by measuring the width and length of the oil pan, then cut a rectangle of 14-gauge steel to size. They then bent the steel to conform to the shape of the pan as closely as possible, creating a relief bend around the drain plug to ensure they could still access it with a socket.

The next step was to apply a generous amount of GE 50-year Silicone to the areas where the skid plate would make contact with the oil pan. They then pressed the skid plate into the silicone, ensuring that the entire surface was covered. Any excess silicone was used to cover the sides of the skid plate, adding extra protection to the exposed sides of the oil pan.

The skid plate was then left to dry, and the oil pan was re-installed with new seals and stainless steel hardware. The silicone created a very strong bond, and the skid plate was able to withstand 10 years of off-road abuse without any issues. This method of attaching a skid plate is not only effective but also inexpensive, costing only about $20.

They can be difficult to install

Skid plates are essential for protecting the oil pan, engine, and other vital components of a vehicle from damage when off-roading. While skid plates can be a valuable form of protection, they can also be difficult to install, especially for those without mechanical expertise.

Belly pans, which offer complete underbody protection, are often challenging to install. They are typically large metal sheets that need to be custom-designed to fit the unique shape of each vehicle model. This bespoke design process adds to the complexity and cost of installation.

Even for experienced mechanics, installing a skid plate can be a tedious and time-consuming task. It requires careful preparation, including cleaning and treating the oil pan for rust, as well as ensuring all bolt holes are level. The process of attaching the skid plate securely and ensuring a good seal can be intricate, especially when working with metal skid plates that require welding or other permanent forms of attachment.

In some cases, creative solutions may be required to install a skid plate effectively. For instance, one individual chose to attach a skid plate to their oil pan using silicone sealant due to the challenges of welding thin steel. This innovative approach required significant preparation and precision to ensure a strong and durable bond.

Additionally, the installation process can be further complicated by the need to remove and reinstall the oil pan. This step adds complexity and requires careful handling to avoid damaging the pan or introducing contaminants.

Overall, while skid plates offer valuable protection for off-road vehicles, the installation process can be intricate and time-consuming, especially for those without mechanical expertise or experience with similar projects.

They can be expensive

Skid plates can be expensive, and their cost depends on several factors. Firstly, different sections of a vehicle's undercarriage require specific plates, and these vary in price. For example, the cost of a protective plate for a gas tank will differ from that of a transmission or oil pan covering. The type of material used also influences the overall cost. Steel plates are typically the most expensive, followed by aluminium, while heavy-duty plastic is the most affordable option.

Additionally, the make and model of your vehicle can impact the price of skid plates. Plates for high-end vehicles tend to have a higher starting price compared to those for common sedans. Sometimes, the manufacturer's brand recognition also affects the cost. Custom-made underbody covers or skid plates tailored to specific requirements can also increase the expense. These are usually crafted by an auto body detailer and take into account the unique specifications of a particular car model.

In some cases, the installation process itself can contribute to the overall expense. While skid plates can be purchased individually for specific areas of a vehicle, this approach can be tedious and costly. Pre-arranged sets that cover multiple critical areas or the entire underbody of a vehicle may offer a more economical option.

It's worth noting that while skid plates can be a significant investment, they also provide long-term protection for your vehicle. By safeguarding crucial components, they can save you from costly equipment repairs or replacements in the future. Therefore, when considering the expense of skid plates, it's important to weigh the potential financial savings and peace of mind they can offer.
