A screeching noise from the front of the motor could be a worn polyrib belt, a bad idler pulley, a bad water pump, a bad power steering pump, bad timing chain tensioners... what did I miss??? First things first. Decide if you want to diagnose it yourself or take it to a reputable shop in your area. Typical labor rates in SoCal are around $120/hr. It should not take very long for a skilled Porsche tech to diagnose the problem and give you a repair estimate.
