has anyone seen this before ? a friend noticed this when he shined light on the inside of the rotor and said it will cause the engine to smoke. jdm engine no damage to the engine everything looked good except for this rotor. sorry for the crap pics.

 

The rotors are made of nodular Iron. Have the local welder TIG weld the holes shut.



Done it many times. No problems at all. Won't hurt the balance enough to notice.

Picture is an aluminum end plate and removable wear surface used for rotary aircraft engines. No you cannot have one. Cuts the weight of the engine about in half.
