Are these cylinders OK?
The cylinder surface is fine, but there is slight pitting as shown.

Paul,
The cylinder top sealing surface is NOT OK! If I am not mistaken ... no gasket or sealing ring is used on 98 mm cylinders.

Thanks Warren. I didn't think so, but I thought I would ask.

Paul,
Those cylinder top sealing surfaces can be machined flat again ... but extra shims will probably be needed to get back to the minimum cylinder height requirement.
