driving home from VA (to NJ) on saturday started noticing a loud clack from the engine when I got into the Baltimore area. Pulled over and figured out when I pulled the wire off of cyl 4 the noise stopped. I figured from the sound I had a bad lower end bearing. I decide to just drive it home and deal with it then, if I made it without completely blowing the engine and getting stuck. I made it home but the engine was making some pretty loud and scary noises....
