HELP!!! Engine Clicking Sound..., help.... Options

[zigy]

*** I am getting this crazy ass "clicking sound" comming from my engine (sounds like when you put penny in a plastic box and shake it fast).

CAR: 1994 Toyota Celica 1.8L DOHC (Automatic)

-basic bolt-ons (no boost)

OK, lets start from beginning...
- 3 weeks ago I bumped the I-355 highway median (Illinois), and just made a small dent on the front left side of my car. I'm just stating this so that you are informed, I don't think that there was any internal engine damage done but I just wanna state every single detail.
- 1 week ago the "clicking sound" was sometimes heard at high RPMs (5000 RPMs and up). But this was only when I pressed hard on the gas.
- 1 day ago the "clicking sound" was heard every-single-time I was in high RPMs and it was getting louder and louder.
- LAST NIGHT the "clicking sound" was really loud and clicking fast, and eventually my car shut off. I had to try 3-4 times to start it and finaly it turned on after 20 min wait.

STEPS TAKEN:
-I got some more expensive Shell 93 Octane
-I changed oil filter and got some Castrol Syntetic oil
-I have checked the spark-plugs and wires themselves

-I have also opened the valve cover making sure that the gasket was not damaged (since I've seen some dark liquid on bottom block)




*** I have no idea whats wrong with my car, the "clicking sound" is getting louder and faster, if anyone has any tips/hints let me know!!!

thanx
