Symptoms of leaking Vac. block gskt?

[2QWIK4U]

Just wondering what some of the symptoms would be if the vac. block gasket was leaking.

Well, while under vacuum you would have a vacuum leak, probably causing abnormally high idle BLM's. While under boost you'd probably see some signs of oil being blown out around the gasket.

Oh, and you can get a replacement gasket from GM for pennies, so if you think it's leaking, do the logical thing...
