pressure guage was bouncing everywhere.

showed up on dipstick. i then added about
a quart and still barely anything on the
dipstick. What is the problem

Sounds like an oil leak.

Make sure the oil filter is tight an doesn't have 2 gaskets between the filter and the mounting boss. Sometimes the gasket sticks to the mounting boss and then when a new filter is installed a second gasket is installed on top of the original. The engine oil pressure will blow the bottom gasket out causing a big oil leak.
