Search is down for me for some reason, don't know why it's not working... anyway...

anyone know how to diagnose/ fix this ailment?
This happened tonight and I didn't get a chance to check my oil level, though I'm fairly sure it's fine.

I also had to have a bolt tapped out today- an A/C pulley fell off the block a few weeks ago- could they have potentially injured my block or hit the sensor?
