Toyota Pickup Crankshaft Seal

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.

Poor installation

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.

Old age

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.

High mileage

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.

  • Tips to Remember in Taking Care of Your Toyota Pickup Crankshaft Seal 27 February 2013

    If you think you don't need to pay much attention to your Toyota Pickup crankshaft seal, think again. Yes, this is just a small part, but it can greatly affect your truck's driving performance once damaged. So if you want to have a reliable and longer-lasting crankshaft seal, take note of these simple maintenance tips:


    Look for cracks.


    Your crankshaft seal will eventually crack and fail. It's just a matter of when. So if you feel like your truck has already traveled long distances, you may want to start checking the seal for any sign of wear as high mileage may translate to a broken crankshaft seal.


    Get the right seal for your car.


    There are different kinds of crankshaft seal, so you need to get the most appropriate seal for your Pickup. Since you're driving a truck, you may want to get the stronger seal instead of the rubber seal, which can easily succumb to excessive heat. Also, make sure that the crankshaft seal you're getting will directly fir your vehicle. Don't just buy one from any auto supply store without verifying the fit.


    Clean the seal and its housing.


    If you're replacing your crankshaft seal, you should always remember to clean the new seal and the seal housing. Doing these steps should extend the life of your new seal as no residue can affect its function. But first, make sure that you clean the seal housing using a cleaning pad and some brake cleaner. And before installing your crankshaft seal, you need to apply some motor oil on the inner part of the seal to remove any particle.


    Coat it with RTV silicone.


    You can apply some RTV silicone on the outer circumference of the crankshaft seal right after you clean it. This will ensure that the seal will be protected from any possible crack that may cause leaks. But make sure that you do this step quickly but precisely as the silicone will harden really fast once exposed to air moisture. Also, don't forget to wipe off any excess silicone on the outer parts of the seal.
