PCV Valve 74 dart w/318

[OwdKasd]

Is there a good reference for the routing of the PCV valve/hose? My PCV is going into the Valve cover but the grommet is too large so there is a leak at that point. The Hose goes right to the Carb. Any help with the correct connections etc... would be a big help.

Thanks,
Gerry

just get a new grommet from the parts store and from the valve right to the carb port... thats it

Thanks 805! I'm guessing there there's a baffle inside the Valve cover under the grommet??? Is the Carb port the same type of vacuum as used for the brake booster?? Is the loose fit/vacuum leaking likely to be causing running problems and poor Idle.

Thanks again!!!

The brake booster gets constant vacuum directly from the intake manifold.

10-4. Thanks.

yea you will have a 3/8 port on the carb for the PCV and a 3/8 port on the intake some where

Awesome! The car's running pretty well for having such a hot cam but I'm just trying to make it better. I didn't think the "Loose" fit of the pcv valve was cool.
How much vacuum should be running to the Brake booster at Idle? Thanks.

It depends on the cam your using, we would like to see at least 13hg for power brakes. One thing you can do is tune with a vacuum gauge to get the highest possible vacuum at idle, in gear.

Thanks. I need to get my hands on a vacuum gauge.

you can always get a coffee can and weld one end closed, then weld on bards and then you have a vac resivour...
