#driveyourlife

rear seal leakFixing a rear seal leak can be as easy or as hard as you would like to make it.  A rear seal leak, or sometimes called a rear main seal leak, is often looked at one of those “car killer” maintenance items.  For many vehicles, the cost of this repair can exceed the value of the vehicle which can make your next step a trip to the junkyard.

Fixing a rear seal leak is such an expensive maintenance item because it always requires removing the vehicle’s transmission and sometimes the engine as well.  Anytime you have to do a maintenance item that requires the removing the transmission or motor from the vehicle you’re often looking at $800 to $2000 just in labor costs depending on the type of vehicle you have and the motor that’s in it.  Since the labor costs are so high on jobs like this, it’s often cost effective to go ahead and do other maintenance items that require motor or transmission removal to try and save paying for that labor twice.  These types of services can simple things like the input shaft seal on your transmission to whole rebuilds of the transmission or motor.

Replacing the rear main seal requires the transmission to be removed because the seal is located behind your engine’s flywheel.  To remove the flywheel, you need to remove the transmission as well.  Also, depending on how your vehicle’s engine is designed, replacing the rear main seal may require removing the engine’s oil pan or other components which will require the motor to be removed.

Replacing the rear main seal in your vehicle is definitely the hard way of fixing a rear seal leak.  To understand what other options are available to fix a rear seal leak, you have to understand why the rear seal might start to leak in the first place.

A rear seal leak is often formed simply due to regular use of your vehicle.  The rear seal is around your crankshaft at the back of your motor.  After miles of driving, the spinning crankshaft can start to stretch or wear the inside of the seal to the point where the seal cannot keep oil from seeping in between it and the crankshaft.  This oil leak can cause a lot of problems like slinging oil into your transmission bell housing and lower your crankcase oil level which can lead to accelerated engine wear.

The easy way to seal the rear main seal leak in your vehicle is to simply restore the rear seal that is currently installed in your vehicle to its original size and shape restoring it’s sealing power.  This will save you the time of removing your transmission and engine which translates to massive cost savings.  To restore your rear main seal, simply add BlueDevil Rear Main Sealer to your engine oil.  BlueDevil Rear Main Sealer is an advanced restoration agent that will restore your rear main seal if it has become shrunken, dried or worn quickly and easily sealing your rear seal leak!
