Best place to use Seafoam?

Through the break booster hose, or through the PCV hose?

I used it through the BB last week. Will it hurt the motor to do it again this week, but through the PCV?

Doesn't hurt anything. I don't know how it is on the 4.0 V6 (OHV) like yours, but on the 5.0 V8 (like mine) you get less coverage of all 8 cylinders using the BB method.
