If a new intake gasket was installed in a 98 Buick Lesabre 3800 v6 and if you pull the oil dipstick with the car running there is a suction into the crankcase that can be heard and felt by placing a finger over the hole is it a vaccum hose?

This is not unusual. The Positive Crankcase Ventilation (PCV) system uses engine vacuum to create a negative pressure situation within the engine for emmissions purposes. All internal combustion engines have leakage past the piston rings, regardless of age. The PCV draws the unburned hydrocarbons that have leaked past the rings into the intake to be burned in the combusion chambers. This also has the added benefit of helping keep the engine oil cleaner by reducing the amount of contamination in the crankcase.

The term "installed" is especially relevant to equipment or machinery, by placing or fixing. It also means to place someone in a new position of authority.

Transmission fluid is added to a 2003 GMC Envoy by removing the dipstick and placing a funnel inside the tube. Fluid is then added and the level checked periodically using the dipstick.

The transmission fluid on a 2005 Dodge Neon is changed by placing a drain pan under the vehicle, removing the drain plug, and allowing the transmission to empty. The drain plug is installed, fluid added through the filler tube, and the level tested via the dipstick.

this can be done by simple removing the dipstick and placing it into the number one plug hole after removing the plug turn the crank and allow dipstick to gently slide to tdc whilst ensuring crank marks are alligned with engine front plate marks.
