Waste-gate ?

Cant remember where i read it, but someone mentioned to connect the vaccuum line from the actuator to strait manifold vaccuum if it wasnt operating. Since i did that, my turbo actually would bleed off boost above 10psi, however that only lasted about 5 or 10 good pulls now it seems like it wont release excess boost again... Im going to assume that my waste gate actuator is defective and that the seal is leaking internally.

Sounds like it or a hole in the vacuum line. Try actuating it with REGULATED pressure from a compressor. If it fails to open then it's shot.

vaccuum line is definately good, i put a brand new one on there... figured it was shot, since i blew the last HG by overboosting lol. tried to mickey-mouse it and the manifold pressure im sure was just to great for the old girl. thanks
