If I recall Lynn's recommendation was to put the end of a new apex seal in the slot sticking up and if the end moves more than 3/16 of an inch - then the slots are too wide (AND that 3/16's is end of life - so it should be way less if I want 1000hrs out of it). The other way he suggested is to (quoting) "stand a new seal on end in the clean groove and use a feeler gage to measure side clearance per the manual. Measure in 5 places across the groove, and try the gage on both sides of the new seal, for bellied or less than straight grooves." Joe Hull Redmond/Seattle WA, Cozy-Mazda Rotary 71hrs
