I dont think that your gasket needs to be replaced after 4 months, I think that the leaks have got more to do with how much coffee youre putting in the basket. You certainly can overdose, or even choke Miss Silvia.
If you have to wrench the portafilter handle into the machine, youve go too much coffee in there.
Another thing that may be causing the leaks is that the gasket isnt completely free of coffee grounds. The coffee grounds that are left on the gasket go hard after a while and diminish the seal between the portafilter and the gasket.
Hope this helps.
