Anyone have info on when to replace the composite camshaft gear on the FJ62? This was changed from the steel gear to have a quieter engine & reduced weight. Friends FJ62 has 200k+ miles on the engine. Still runs well. Looking for someone that has data and maybe pics of the gear after xxx miles. Is there an easy way to check the gear without pulling the engine? Will a steel gear fit and bolt up if the composite gear is worn? Any information is appreciated.
