Guys,

Can anyone in this group determine the rotor al= loy?  It is ductile cast iron.  I have two rotors that are '90 = high compression rotors that have been damaged by broken apex seals. &nbs= p;Ed says that they are very scarce and expensive.  I would like to = know if anyone has ever welded up the apex groove and then machined the g= roove to 2mm and used the rotors again.  What would be the downside = of buffing out grooves on the face of a rotor?  This is for an auto = application NOT aircraft application.  Bottom line question: Can rot= ors be repaired?  Piston replacement is cheap....not so with rotors.=   Your input, please.
