What if I forgot to put the oil filter gasket on?

How screwed am I if I didn't put one in?
What is the worst that could happen?
Any expert opinions would be appreciated.

Also, I put 9 1/2 quarts in and it still says I am 2 or 3 bars from full on my Boxes cpu. What is that all about?

You will have an oil leak................ Why not pull the housing back off and look to see if there is a gasket, and even if there is, replace it. You will lose very little, if any oil in the process and can top off your oil level, which is apparently low either due to the leak or because you underfilled it...............
