Next time you replace it use some silver silicone on the outer edge and cut half in inch off of the spring inside the seal.

some ppl told me to doble it what do you think of that ?

blown seals are usually blow-by related. Double the seal is an old trick that rarely works. Does the PCV system work? if you have it to atmosphere I'd do it the way the factory intended. If that is fine, then you may have much more significant issues like the rings being shot (though you should see smoke), or you may have crank walk (just a guess here that movement may be wearing the seal prematurely). Have a friend step on and off the clutch and see if the pulley moves...
