No Ported Vacuum
Hi All,
I am not getting any ported vacuum going to my EGR valve. I checked the vac
at the connection that is on the top of the Carter BBD - the one on the
engine side of the carb and there is no vacuum at any RPM. Anyone have any
ideas why?
Thanks in advance,
Steve

Re: No Ported Vacuum
Because the vacuum at that port depends on load? Have you triple-checked to
make sure that it is the correct port?

Re: No Ported Vacuum
Then I would guess someone put the carb's base gaskets on wrong. There
are channels in them that direct the vacuum flow.
Do you have manifold vacuum at any ports?

Re: No Ported Vacuum
One other thing, the hole could just be plugged. Maybe try spraying
some carb cleaner into the nipple to see if it comes out on the inside.
