My 51 stovebolt has been converted to a 235 w/ a T-5 tranny. About 10,000 trouble free miles since being converted

Recently makes noise only when the clutch is depressed. Inspected the situation & found my release bearing up against my clutch all the time with no free play. I figured it wore itself out so I had the bearing replaced. Pilot bearing was inspected & found to be ok.

All back together...50 miles later the noise returns....intermitent.

I'm stumped...don't know what to check next?

Any help will be appreciated.

Thanks
