What is causing my front camshaft oil seals to leak?

I wish you gave a lot more information, but your question suggests that you have replaced the front seal at least once with unsatisfactory results, I have seen some failures due to a groove that was worn into the crankshaft where the seal rides or residue on the crankshaft that makes proper sealing impossible. I usually sand the crankshaft with a fine emory cloth to clean the crank. Check the fit on the crankshaft before you install to be sure it is the right size and will fit both the crank and the cover. I always put some fresh clean motor oil on the seal so it is lubricated on initial start-up and isn't run dry that could damage the new seal. Use a seal installer or fashion something that enables you to install the new seal without damage and be sure it is installed squarely. Sometimes on the outside around the seal I put some silicone sealer to ensure a good seal. And lastly I use sealer on the balancer to crank and the threads on the crank shaft retaining bolt. also be sure the PCV system is working. This should do it. Good luck.What is causing my front camshaft oil seals to leak?
It could be a number of things but mostly just use. I don't know how old the car is %26amp; how many miles on engine,etc. Usually the leak is due to age because the seals are a sealed item and not subject to the elements. Again, not knowing Year-Engine-Mileage, etc, It's hard to say what is the cause. Even though these ';Answers'; forums make diagnosis hard enough, if not impossible.What is causing my front camshaft oil seals to leak?
A bad seal. Three times is a charm. Sorry what ever you are doing you need to change and correct it. Talk to a home town Auto store Mechanic and sometimes they can give good directions to your very problem.


Good Luck.


Just a shot in the dark-- But so you have a torque wrench??


are surfaces cracked?? or scratched?? and that is perma teks its ok but is it what the process calls for??



Did you pre lube them before installation?


I do.


Is the seating surface intact or is it worn?


It the seating surface is out of specifications they will not seal right no matter what you do. I don't know if there is a speedy sleeve for this area.
Worn with age/usage on existing oil seals


Improper replacement installation workmanship



Sounds like the front of the crankshaft is worn replacing the seal will not do much good.
are you using the right weight oil
