Would this cause no boost to build up at all?

Even if the seals were completely gone I'd still believe you could make boost. I don't know any info on the car but main issue for no boost is a wastegate not closing, severe pre-turbo exhaust leaks, blown turbo.

Those seals are much more likely to cause an idle surge than they are a serious drop in boost.

Ok, well I have no boost and that's the first leak I found. I still need to check my exhaust manifold.

Do you have an aftermarket boost gauge? Does the car pull vacuum but never even nudge past zero psi? My brother and I will both be in Fairport this weekend if you want a hand.

You can actually have a 5 inch long gash in your intake manifold and still make boost.
