vac line from turbo to boost port, vaccuum port left open

when i took it apart i didn't notice any leaks, but when air is blown into the boost port, i can feel air coming out of the vaccuum port, is this normal or should i look more carefully for a leak on the top of the diaphram?

The only air you should feel comming out of the vacuum post would be the air from the diaphram moving. how much air ar you blowing into th boost port? the wastegate cant handle 120psi that a compressor is capable of. you might have a leaking diaphram.

thanks it was when i had the spring out i was just blowin in it to see if it opened but i didn't think of the fact that it could be the air in there already being forced out
