Help! an engine bearing on it's way out? :(
This clip: http://www.youtube.com/watch?v=sVMUKilwk98
shows my engine in idle, listen closely you can hear what sounds like a unhealthy bearing noise thats separate from the normal loud injector ticking, coming from the timing chain side of the engine.
Notice at the end of the clip when i move the camera towards to middle of the engine, the noise quietens. In person, its quite allot more audible.
Anyone have a similar sound on their car? Or have any opinions on what it might be? I hope it isnt anything thats going to cost a heap to fix

j/k - it almost sounds like a diesel on my computer. Could very well be. Throw some Lucas oil treatment in and see if it makes a difference. Does the sound get progressively worse with higher rpm's/? Does the sound get "faster"?

Hmm not that i've really noticed, when revving it at idle, the increased rpm sort of drowns out the bearing noise. Ill give it a try though and see what i can hear. About it sounding like a diesel, i always though that was a bit of a loose timing chain, i might need to replace the tensioner.
Thanks for the help so far!

try to take another video from underneath the car with the plastic under-tray removed. also, put your ear to the handle of a screwdriver and probe around the oil pan and block. you should be able to isolate it. to me it does indeed sound like a bearing, but the audio is a bit muffled.
