I'm going to tackle replacing the AOS on my 2002 base 986.

Some tutorials mention replacing the Crankcase Breather Hose ( part # 99610714506 ) as part of the job. Does anyone know if this is required or not? It's not clear to me why the original one can't be reused, saving $90 on the job cost.

Thanks for any tips!
