I just finished overhauling the engine, changed 20 of my cylinders with a piston kit. Gaskets weren't changed, no seal on the the crankcase halves. Antifreeze is showing up on the mag and pto plugs. Do i need to change my head gaskets? Seal the crankcase halves?
 

If you had the crankcase apart you need to seal it with yamabond 4 or there is a permatex product that works the same. I cant remember what it was called. If the gaskets are old I usually replace them. You can get away with using the permatex copper gasket spray on the old gaskets. If it were me I would seal the crankcase and put new base and head gaskets on.
