i like all the info here and have been thru as much as i can but haven't been able to find exactly what im looking for. im currently looking at a used spintex 210 system. the owner says before he took it off for a different setup he had "a vacume leak whitch was found by his mechanic with a smoke test" he also said the "bypass valve" is what they think was causing a leak and others have changed the o-ring to solve the issue. he said it was still making boost just not as much in the low end. does this seem common or have any of you experienced what hes talking about? i cant look at the unit myself cause we are states apart. i also haven't received pictures of this bypass valve yet but supposed to be sending soon.
