Did the same thing and installed a brake pad backwards. Didn't make it out of the driveway before I realized something was way wrong thank goodness.

Anyone that has worked on cars for any length of time has done something equally as dumb.

Brain farts are why I now use an engine run stand to work out the kinks before installing an engine now.

Nothing more frustrating than spending days detailing parts and engine bays only to have them sprayed down with whatever fluid chooses to find its way out.
