You didn't damage the unit by installing dual 40's. Also, if the vacuum unit is leaking, your car will run like complete crap--especially with sidedrafts, because the vacuum port affects only one cylinder. It sounds like the vacuum unit control valve is stuck.

I haven't been driving my '02 for a while (just replaced the head gasket) and now I have a hard feeling at the brake pedal. It feels as if the power assist isn't working. If I start the car, the brake pedal does not get easier to push. The vacuum hose is hooked up to the manifold, and if I disconnect it from the assist I can feel that it is sucking like nobody's business.

Is there anything I should check before I replace the vacuum assist unit? I recently put dual 40's on and am wondering if that caused more vacuum and could have damaged the unit.
