The machine shop installed the camshaft and bearings. Note: This occurred with two different camshafts and two different sets of bearings.

I agree spring pressure is relatively low. Comp Cams 924 springs.

I used a borescope to take the pictures, from what I can see with the borescope the cam lobes look ok. I dont see any flat, wiped or damaged lobes at this time.

Would the proper repair be to install new camshaft bearings and have each one clearanced for the camshaft being used or is it possible that this block/cam tunnel is too far out of round?

Thanks!
