Boost, no boost, boost, no boost?!?!?!
 

Finished puttin the engine back together, hooked everything back up correctly or so I thought, and when I drive I get no boost, get off the gas, then back on and magically boost but only 5 or 6 lbs????? what am i doin?:??

im no expert but it sounds like its the Vacume Chamber. its not getting complete pressure so it wont actuate the boost. May need a new one, they are plastic so easy enough to crack.

Leak coming off the vacuum chamber. The check valve is the most common reason. I'd start by replacing all the check valves - you can get enough viton diaphragm ones to do the car for $25.
