Think maybe he means the exhaust valve stem is loose in its guide. That would make more sense as far as the oil consumption goes. But still not for the head and piston replacement.
update for those who care...Suzuki warranty approved the parts...
new pistons and head etc....it was valve guide issue...I got some clarification....the svc mgr knows little, the techs are the reasonable answer guys
