Where did you buy the vacuum valve? Mine is broken also. ThanksThank you for your inputs. I reinstalled the turbocharger yesterday and changed the vacuum valve. Test drove it and it seemed ok. Cleaned the engine with degreaser and rinsed it with water. When I test drove it again today, it feels like it's in limp mode again. I guess I need to check the lines and if there's anything that came off or may have been affected by the water when I rinsed it this morning.
