I had quite a unusual experience happen about 30 minutes ago.
I pull out of my neighborhood onto the main road and get on it, well in the process at around 5500 RPMs, I hear a loud POP and a bunch of what sounds like metal and plastic hitting the pavement and bouncing and hitting my undercarriage. With all this happening I didn't even notice that my car had completely shut off, so at this point i'm coasting and come to a spot in the middle of a turning lane. Well I get my car safely off the road out of traffic and I proceed to try to figure out WTF had happened. I thought I may have blew a bearing or a rod through the block completely annialating my bottom end.
So i'm walking down the street looking for what came out and I proceed to pick up a piece of plastic in the road which was the top plastic cover to my PTU .

Get the car home and throw in my old one and it started right up fine
