[QUOTE="FordTechOne, post: 1905524, member: 35543"] What is the maintenance history of the vehicle? Were all applicable recalls completed? That’s internet speculation from people who don’t understand engines; oil pressure reaches the heads within seconds. If there were a lack of oil pressure to the heads the engine would be damaged. Phasers do not need oil pressure on a cold start. You can try checking the wastegate linkages through the fender wells while duplicating the concern to see if their movement matches the noise. Can you only hear the noise with the hood open and blipping the throttle? Or is it audible in the cabin during normal driving? [/QUOTE]
