Default Is it possible to have a boost leak and not throw a code or get a CEL?

I am asking because for the first time my turbos are a bit louder (when cold) then they have been in the past...or I just pay more attention now.

Also, I have checked via search and didn't find it, but does anyone know if there are any tech docs on how to drop the engine and trans? I don't plan to do it...but I would like to read up on it and see how its done.

Thanks as always.
