Contour Enthusiasts Group Archives Forums General Troubleshooting knock at 3000 or higher rpms

i too have a knock.
i have a '97 v6 duratech w/ 85k. atx.

knock occurs in 1st gear @ 3200, 2nd gear about the same, and in drive it doesn't knock until over 4 grand. idle and non-heavy driving have zero knocks.

any insight would be great.

thanks,

tim.
