Apex Location            Base            Top
 
Seal1                        1.99mm        2.16 - 2.26mm
Seal2                        1.98mm        2.22 - 2.25mm
Seal3                        1.98mm        2.18 - 2.20mm
 
Clearly the slot is larger at the top - is this due to design or is this due to wear?  Lynn??? Anybody?
 
 
Hi Ed,
 
I still have the brand new rotor that was dropped by the ceramic coaters, and I just measured the two un-smashed apex seal slots.  I also measured the slots on the dead rotor that was involved in my oil out adventure.  All the slots measure 1.89mm, with no sign of being larger at the top of the slot than the bottom.  
 
Cheers,
Rusty (my kingdom for a decent contractor)
