My engine ticks when it is cold and I am trying to figure out why. I had the cam covers off today to see if it was anything obvious. When I pulled the lash adjusters I could not compress any of them by hand at all. To reinstall them I had to compress them with a c-clamp. Once I c-clamped them they would move very freely but only to the point where I compressed them with the clamp. Is this normal? My followers and cams looked great.
