Has anybody out there had trouble with cigarette seals leaking shortly after a motor rebuild??? I build at least 1 or 2 motors a month and I NEVER had cig seals leak but the last few motors are starting to leak at the cig seals???? The seals seem to get very soft and Im also having the same issues with the rear half moon seals too. They seem to swell up to twice their size. I have not changed the motor oil that I have been using. And I also add a half bottle of Red Line break in additive on start up. Is this just me????? Anyone?
