Question v-10 vaccum problem

Hey does anybody know what would cause my 2000 v-10 F-350 to create vaccum in the crank case ? I have changed the pcv.
Thanks

A vacuum in the crank case is not a bad thing. There should be some. Unless it's excessive.

What exactly is happening that makes you think there is a problem?

The only way I can think of excessive vacuum occurring is if the fresh air PCV hose was plugged.

There should be some type of breather hose/filter to allow clean air into the crank case. Check that for collapse or plugging.
