Depends on which seal and which model vehicle, but it involves replacing the bad seal. Rear main seals usually aren't that difficult - though again, depending on the model, it may involve dropping the transmission. Front seals or crankshaft seals involve pulling the harmonic balancer (if you have one), pulling the timing cover (if you have one) pulling the old seal from around the crankshaft and tapping the new one into place.
That would depend on what oil seal you are referring to. There are many oil seals.
replace the seal
There is only one way. Find the leak and repair whatever is causing the leak. Bad gasket, seal, or broken part, whatever.
There are several types of oil leak sealant for a 1992 Honda Accord. A few of the sealants that can be used are Bar Leak's seal repair, Lucas Oil, and Blue Devil oil leak sealant.
An oil leak on a 1995 Toyota 4Runner can often be repaired by replacing the damaged gasket or seal. Tightening the oil pan bolts can also fix some leaks.
A 2001 Ford escape differential leak is usually caused by a bad seal. Replace the differential seal. The new seal should stop the oil leak.
The cost to repair an oil leak on a 99 Ford Escort will usually cost between $250 and $500 depending on the cause. A worn seal or gasket is much cheaper than a bent pan or a ruptured block.
The oil leak is probably comming from the top of the oil pan there is a rubber gasket that goes between the oil pan and the water pumb which would make it look like its comming from the harmonic balancer, try replacing the oil pan gasket this should fix the problem. New answer: There is a small round oil seal / Harmonic balancer seal that fits in the timing cover and the balancer slides through the center of it. That is probley were your oil leak is. Most of the time the balancer itself gets a groove wore in it over time from that rubber seal running on it. You can repair the balancer by buying a Harmonic balancer repair sleeve/ speedy seal. Also replace the front timing cover seal.
It depends on where the leak is and what is causing the leak.
You probably need to drop the oil pan down, remove the front cover and replace the cover gasket and main seal.
There is a seal to seal the pan to the block. This seal goes out mostly do to lack of oil changes. Change oil then add a stop seal leak additive that closes off the leak with no harm to the engine. It works!
You need to replace the oil seal.
If there is leaking around the base of the distributor, and you will need to replace the seal. The distributor oil seal is a paper gasket or rubber O-ring, and the distributor is removed to replace either one if the seal is leaking. It is easy to change, just remove distributor and change the seal.
try castrol oil stabilizer - it will stabilize the oil and reduce the leak.
rear main seal
Accel oil seal. 4 oil seal must be replace
That depends on where the oil leak is, is it in the motor self or is one of the seals leaking?
It all depends on where the oil leak is located. First find the source, then know your mechanical abilities, repair your self or find a person that has done this repair before to tackle it for you. There is nothing you can add to the crankcase that will stop an oil leak.
You will have to determine the source first then we can help you stop it. More info please.
this can be an expensive repair. it depends on where the oil is leaking from. sounds like it may be the front seal on the engine. check that the oil pan blots are not loose. as small as this leak appears, the easy fix is to purchase a bottle of LUCAS brand engine oil additive,and add proper amount to engine. if the seal is the problem, this additive will rejuvinate the oil seals and most often will stop the leak. HAD THAT PROBLEM AND FOUND OUT IT WAS A BAD OIL PRESSURE SENSOR. ALSO CHECK AND SEE IF YOUR OIL FILTER IS SCREWED ON TIGHT.
be more specific.. wheres the leak..?? you might have to replace a seal.. or a pipe then recharge the system
The rear main oil seal would be the bigger repair job on most engines.
In my experience it will leak.
it spills. another way oil commonly leaks is when a seal wears out or fails.
