I have a CSVT E0, 63,000 miles. Im the second owner and it receives regular maintenance and 6 quarts or more of mobil 1 for every oil change. I try to keep it easy on right hand turns so now that I am hearing a knocking, rattling sound around 3-5k when I go wot in first gear I am kinda confused. I don't hear the sound in second or third or at idle. If I rev it while in neutral it produces the same sound. Is this the infamous rod knock of the contour?

This condition has not gotten any worse over the last month, but definitely not better. I'm asking this question to see how much time I might have left before the inevitable 3.0 swap is necessary. Thanks for any input, it is very helpful. Long live CEG.

P.S.- I know I should stop driving it if it is making any noises, but frankly I don't care too much if the engine dies, I'm already saving for the 3.0.
