Can we use 2-piece apex seals with used rotor housings?  All the
used rotor housings that I have seen (admittedly, only off of 4
engines) have a groove around the outside edge where the small
triangular piece of the 3-piece seals has caused the chrome of
the rotor housing to flake off.  I understand that this is pretty
common.  Will this groove allow too much blowby if used with a
2-piece seal?
