What would happen if u didnt install the waste gate valve seat?? I figure it would'nt build up boost seeing its creeping out the little crack going around the valve where the vavle seat would go to seal it right?? I ask this cuz i bought a XSPower Waste gate off some one and i noticed it was missing something and from looking at pictures of other waste gate it turned out it was missing that vavle seat. So now i need one but just wanted to know what would happen if that vave seat wasnt installed.
