So is this deformation at the top of the cylinder general knowledge ?
I didnt know until ,y engineer pointed it out to me
How and why would lomger rods help this ? It doesnt make sence to me. The ability of a stud to stretch instead of being hard which will pull the block makes sense. To achieve a better stretch = longer studs, Ferrari has 12 inch studs
