Below is a full guide that should assist you to correct a leaky oil pan with the help of JB Weld. Here we go;

Step 1: Emptying the Pan

Start by draining the oil from the pan, ensuring it doesn’t seep. Just try your level best to drain it.

Step 2: Thorough cleanliness

Your safety should come first and therefore putting on gloves can be the best action. You are allowed to use paper towels and brake cleaner plus any available anti-oil cleaning material. What you need to be sure is to leave the oil pan free from any spot.

You should never cease until you spot the crack you plan to work on. Sometimes there might be several cracks, but if it’s your lucky day, you can easily spot tiny c-shaped cracks. Additionally, you should evaluate and determine whether the pan allows patching or not.

In situations where the crack is small, then you can go on and give it a try. You need to understand that even a simple crack has the capability of emptying your crankcase.

Step 3: Sanding

The next step will be to sand the given area until it not only becomes rough and nice. Doing so is necessary to accommodate adhesives. Some experts will refer to this as a microsurface.

Now that the surface is rough and clean, try evaluating the seepage. It doesn’t matter how long you wait, what matters is to see consistent oil seep from that crack.

Sometimes going straight to the silicone won’t help, this means that you should first cover the area with something then followed by the silicone. Patching the crack can leave the substance useless and oil soaked. Therefore, if the seepage is worse, advance to the next step which will force you to change the gloves.

Step 4: Get an oil containment bowl

Get an oil containment bowl

Experts recommend using a small washer from your alternator pulley of the Beetle. The component comes with a small shape with a diameter of 1 inch diameter, containing an open bottom. You should then use the JB weld and penny to seat the bottom. Give it some times to set before testing.

Additionally, you should place the paper shop towels in the cracks to act as an oil-slowing device. The next thing will be to JB weld the whole bowl on the crack.

Remember, anything like a bowl-like washer can work great, as long as it features a bondable rim plus a small dish area. Try to observe whether the oil drips in the bowl to soak the tiny paper towels. The oil should not escape from the bowl bottom.

Step 5: Coating the JB welded cover with grey silicone.

This step involves applying a thin layer of silicone that won’t interfere with the functionality of the bowl. Under the same step, you are required to substitute the gloves because oil contamination can ruin the entire state-of-the-art. More so, you should wait for the silicone to completely cure before doing anything.

Step 6: Applying the second coat

Before applying another coat, you should first check the workability progress. Up to this juncture, there should be not a single drop of oil seepage. Apply the next thin silicone coat and then don’t forget to change the gloves; get the clean ones.

Step 7: Curing

There’s nothing you can do to achieve this step rather than leaving it overnight. In situations where a single night isn’t enough, don’t lose patience. You should only test the artwork when it’s fully cured.

Step 8: Final inspection

Before you start filling up your engine with oil, make sure there’s no kind of oil leakage. In case there’s no oil drops, the process was successful; if not, you are pretty boned.

Arriving at this point requires some attention and keenness. You would rather own an ugly oil pan, but with no drips.

Well, after considering the above step, the best result is what you should expect.

Step 9: Refilling the engine with oil

The last thing you are supposed to do is to fill the engine with oil. Before getting a new oil pan, give a trial to JB weld and you will never regret it. It can be suitable for those fellows operating under financial constraints.

Before arriving at a protective plate idea, consider a temporal solution. However, oil pans are not fun parts, meaning that they can still be fragile.
