MattG60

hi ive got a problem with my corrado g60. the rubber seal on the oil filter keeps popping out dumping all my oil on the floor. ive been told it is a block in the breather pipes, hich causes an increase in pressure and it is finding a way out through the filter. but I cant see why it would come out of the filter, when the weakest point would surely be the dipstick??!! all help is much appreciated
