So I got my block off plates for my ACV and EGR. I want to put a bov where the bottom vac hose connects in between the turbo and intercooler. I know you can block it off but I'm just making sure I can block off that line without problems.

FYI I have a 88 turboII, Thank you!

You can't block it off without problems. Disabling or removing the BAC will cause idle to suffer. The BAC stabilizes idle under electrical & mechanical load.
