Here is mine:http://smg.photobucket.com/alb...9.flv (ignore the heat shield thumping near the end, and the partial use of the F word)

I found this on youtube:http://youtube.com/watch?v=wNH9zDBCHSo

Sounds similar, no?

Funny thing is, it just started doing that constantly. I didnt drive it, but I'd just cranked it up after I finished doing a compression test, and got 160-162 on ALL 4 because Im about to try and sell it. Go figure.

that other guy deff has bad rod bearings. you can hear it get bad when he revs it up.do this, pull each plug one by one. if the sound quits on one cyl, then its a rod knock on that cyl.

Dont waist time pulling plug wires you have a bad bearing and need to tear it apart to see what else you damaged. You keep running it and revving it up and your gonna damage the crankshaft even more.Your diffenetly going to have to resize your rods and have your crank turned and polished and replace the bearings, once you spin a bearing and get rod knock the connecting rod is making contact with the crank and that tears it up. This is why you hear the clanking noise.

why not just swap it? you could get a cheap *** swap for like 200, for either kae or de. or whatever else you would want but it wouldnt be that cheap.
