Common Culprits behind a Leaking Toyota Pickup Crankshaft Seal
The Toyota Pickup crankshaft seal can break and cause an oil leak that will affect your vehicle's driving performance. While replacing the seal with a new one is the best solution, you need to know, though, the common culprits behind this problem. To help you know how to prevent your seals from leaking, take note of these:
Broken rubber seal
If the crankshaft seal on your Pickup is made of rubber, then chances are it will crack or break much easier and faster than the one made of combined materials. Rubber seals are more prone to damage when exposed to excessive heat. And admit it, your engine and other components heat up every time you drive your truck for a long time. Once the seal cracks, the engine oil begins to leak, leaving you with no other options but to buy a replacement seal. Getting another rubber seal is acceptable, but you may want to fit a more durable crankshaft seal to avoid this problem.
You may have to re-install the crankshaft seal in the event that it starts to leak again even if you have just previously replaced it due to an oil leak. But this time, take your time in fitting it to make sure that it's properly installed. After all, a poorly installed crankshaft seal can be the reason for the leak. So before you suspect the other components for causing the leak, you must check the seal first.
If the crankshaft seal on your Pickup is already old, it's just logical that it will wear out anytime soon. And when it does, you can expect it to have cracks that will allow oil to seep out and eventually leak. In this case, it's best you replace it should it get damaged.
Having high mileage can be the reason behind the failure of a crankshaft seal that results to an oil leak. If your vehicle has traveled long distances, this means that the seal has been exposed to heat, stress, and friction that can be too much for the seal to handle. That's why it's important that you have your truck's crankshaft seal checked if it already has high mileage.
