Can't find vacuum check valve on my 1987 740

I've been looking for any and all vacuum leaks possible. Right now I'm
looking into why I get hot air pumped into the car and little to no air
coming out of the vents, even with the fan on high.

I'm going to check under the dash, but wanted to make sure I checked
under the hood first. I;ve looked and looked and on my B230F engine I
don't see any black and white vacuum check valve near the firewall, or
near the manifold, either.

Can someone give me any specifics on exactly where I need to look on
the engine?

Thanks!

Finally found it after starting from the accelerator, tracing through
the firewall and it was under conduit.

It was fine.
